No-bake energy bars: weighed recipes and what they actually contain

A no-bake energy bar holds together because of three things: a dry base that absorbs, a sticky binder that glues, and enough fat to stop the whole thing crumbling. Roughly 45 % dry base, 35 % binder and 20 % fat by weight, pressed hard, chilled for two hours. Everything else is flavour.

What these bars do not do is worth saying straight away. They are not lower in sugar than shop-bought ones: the three recipes below come out between 22 and 24 g of sugars per 100 g, against 20.4 g for the average retail cereal bar measured in the French Ciqual composition table. They do not preserve nutrients that cooking would destroy, because the rolled oats you tip into the bowl have already been steamed and dried in a factory. And they are not a source of protein in the legal sense, as we will see.

What they do give you is different: you know the exact ingredient list, you choose the ratio of dried fruit to nuts, and twelve 37 g bars cost you three or four francs of raw material rather than two francs apiece.

The three-fraction rule, so you can stop following recipes

Every raw bar recipe is a variation on the same structure. Once you have it, you improvise with whatever is in the cupboard.

The dry base absorbs moisture from the binder and gives body. Rolled oats, puffed quinoa, puffed rice, toasted buckwheat, desiccated coconut. Oats dominate because they are cheap, neutral and rolled: the crushed surface of the grain drinks fast. Thick flakes give a bar that slices more cleanly; fine flakes give a smoother paste that is stickier to cut.

The binder is a low-moisture, sugar-rich dried fruit worked into a paste. Dates are the reference because they are the stickiest: 64.7 g of carbohydrate per 100 g, all of it as sugars, and only 7.3 g of fibre (Ciqual). Dried figs are a step less sweet at 49.2 g of sugars, but carry more fibre at 9.72 g and far more calcium, 167 mg against 44.9 mg. Prunes give a softer, darker bar. Raisins, at 70.3 g of sugars, make a poor binder on their own: they never turn into a paste, they stay as lumps.

The fat comes from a nut butter or from the nuts themselves. It coats the dry particles and stops the bar shattering under the tooth. Almond butter, peanut butter, tahini. Without it the bar is dry and breaks.

Two adjustments then cover everything. Too crumbly: add binder, one date at a time. Too sticky: add dry base, one tablespoon at a time. Do not fix it with water, except in tiny amounts, for reasons of shelf life covered further down.

No-bake does not mean raw

This is the most common confusion, and it has practical consequences.

Retail rolled oats are not raw. Oat groats go through a heat treatment called kilning before rolling, precisely because their lipases would degrade the grain’s fats within weeks of storage. A study published in Foods in 2024 measured that rise: in dehulled, unkilned kernels stored at room temperature or at 37 °C for up to 64 days, lipase activity increased over time despite falling moisture content. The authors established that saturated steam at 90 °C for 30 minutes followed by drying at 100 °C for 30 minutes inactivates all lipases. Your oats have therefore already met heat, and that is exactly why they do not go rancid in your cupboard.

Some ingredients that turn up in bar recipes have never been heated, though. Raw wheat flour and raw chickpea flour are among them. A Swedish study published in Access Microbiology in 2023 analysed 200 bags of retail wheat flour covering 87 products and 25 brands: 12 % were positive for shiga toxin genes and 11 % for intimin, and eight Shiga toxin-producing Escherichia coli isolates were recovered. Organic, wholegrain and small-scale production made no significant difference. Flour is a raw agricultural product that has passed through no kill step.

The consequence is simple: do not add raw flour, of any grain or pulse, to something that will never be cooked. Oats do not carry this problem. If you want more protein, use an ingredient designed to be eaten as it is, such as a protein powder intended for direct consumption, more seeds, or more nut butter.

Three weighed recipes, and what is really in them

The compositions below are calculated ingredient by ingredient from the 2020 Ciqual table published by ANSES, summing each weighed ingredient and dividing by the number of bars. They do not replace a laboratory analysis, but they give the right order of magnitude, which a recipe without numbers never does.

Oat, date and almond

For 12 bars of roughly 37 g:

  • 200 g rolled oats
  • 150 g pitted dates, 8 to 10 depending on variety
  • 50 g chopped almonds
  • 32 g almond butter, 2 level tablespoons
  • 12 g chia seeds
  • a pinch of fine salt

Blend the dates alone until you have a paste that rolls into a ball in your hand. Then add everything else and pulse: five seconds, scrape the sides, repeat. Continuous blending heats the almond butter and turns the mixture oily. Press into a 20 × 15 cm tin lined with baking paper, using the flat base of a glass, until the surface is smooth and compacted. Pressure matters as much as the recipe: a poorly pressed bar crumbles when you cut it. Two hours in the fridge, then cut with a straight-edged knife wiped between each cut.

Per bar: roughly 140 kcal, 4.3 g protein, 18.5 g carbohydrate of which 8.5 g sugars, 4.9 g fat of which 0.5 g saturates, 3.8 g fibre, 44 mg calcium, 52 mg magnesium.

Cocoa and peanut

For 10 bars of roughly 36 g:

  • 150 g rolled oats
  • 120 g pitted dates
  • 70 g peanut butter with no added sugar or oil
  • 15 g unsweetened cocoa powder
  • 10 g ground linseed
  • a pinch of fine salt

Same method. The peanut butter provides both the fatty binder and much of the flavour; check the ingredient list, since many brands include sugar and palm oil. Unsweetened cocoa is a dense ingredient at 22.4 g protein, 29.5 g fibre and 500 mg magnesium per 100 g according to Ciqual, but the recipe uses only 15 g of it, which puts that contribution in perspective.

Per bar: roughly 141 kcal, 4.7 g protein, 17.8 g carbohydrate of which 8.7 g sugars, 5.2 g fat of which 1.0 g saturates, 3.5 g fibre, 51 mg magnesium.

Coconut, cashew and date

For 10 bars of roughly 40 g:

  • 150 g rolled oats
  • 120 g pitted dates
  • 60 g unsalted roasted cashews, chopped
  • 50 g desiccated coconut
  • 15 g sunflower seeds
  • a pinch of fine salt

This version is the richest of the three, and above all the most loaded with saturated fat: 9.2 g per 100 g of bar, against 1.4 g for the oat-date-almond version. Desiccated coconut contains 57.7 g per 100 g (Ciqual), and the NHS explicitly lists coconut oil and coconut cream among plant sources of saturated fat, alongside palm oil. UK guidelines set a maximum of 30 g of saturated fat a day for men and 20 g for women. Two bars of this recipe deliver 7.4 g, a third of the female figure. That is not a reason to drop it, it is a reason not to make it the everyday version.

Per bar: roughly 167 kcal, 4.3 g protein, 18.3 g carbohydrate of which 8.7 g sugars, 8.0 g fat of which 3.7 g saturates, 3.7 g fibre.

Free sugars: the point that changes how you read the label

A date bar feels unsweetened because it contains no added sugar. The official classification says otherwise.

The NHS defines free sugars as all sugars added to a food, plus those naturally present in honey, syrups, nectars and unsweetened fruit juices, purées and smoothies. Here is the decisive part: the sugar in a whole fruit is not a free sugar, but as soon as the fruit is juiced or puréed, its sugars are released from the cell structure and count as free sugars. A whole date you chew is not in the same category as blended date paste.

UK guidelines cap free sugars at 30 g a day for adults, 24 g from 7 to 10 years, 19 g from 4 to 6, 14 g from 2 to 3 and 10 g at one year old. Two bars of the first recipe supply around 17 g of sugars, most of it from the date paste. That is over half the adult cap, and more than the entire daily cap for a four-year-old.

None of this condemns the recipe. It simply says that a date bar is a sweet food, to be treated as one across the day, rather than a neutral food because it is homemade. The NHS adds a point that applies directly here: dried fruit is kinder to teeth eaten as part of a meal than as a between-meals snack, because it sticks to tooth surfaces.

What Swiss law lets you claim, and what it refuses

If you sell your bars at a market, or simply want to know what the nutrition argument is worth, Annex 13 of the Swiss ordinance on food information (OIDAl, RS 817.022.16) sets the thresholds.

A “source of fibre” claim requires at least 3 g of fibre per 100 g, or at least 1.5 g per 100 kcal. “High in fibre” requires 6 g per 100 g, or 3 g per 100 kcal. All three recipes clear the first bar comfortably, at between 9.4 and 10.3 g of fibre per 100 g, and they also clear the second: they exceed 6 g per 100 g. One bar delivers 3.5 to 3.8 g of fibre, against the 30 g a day recommended for UK adults, where average intake sits at around 20 g.

Protein is another matter. The ordinance does not count grams, it counts share of energy: “source of protein” requires that at least 12 % of the energy value comes from protein, “high in protein” requires 20 %. The three recipes land between 10.4 and 13.2 %. Only two of them scrape past 12 %, and none comes near 20 %. A bar of cereals and dried fruit, however well composed, remains a carbohydrate food. If protein is the goal, a handful of almonds and a yoghurt does the job better and faster.

The “no added sugars” claim in point 19 is, by contrast, technically accurate for these recipes, provided you leave out syrup and honey. The ordinance then requires the words “contains naturally occurring sugars” alongside it. That obligation tells you everything: the legislator anticipated that the phrase would be misread.

Shelf life is governed by water, not by cold

A raw bar keeps because it is dry, not because it is chilled. In its 2012 opinion on composite products, EFSA identified the four factors that govern microbial survival and growth in a food: water activity, pH, temperature and storage duration. The opinion makes a point that bears directly on bars: in a composite product, moisture migrates between ingredients, and you have to reason on the most permissive combination, which is often at the interfaces.

Translated into kitchen practice, that gives three rules.

Do not add water to rescue a dry mixture. Every spoonful raises the water activity of the whole batch and shortens its life. If the paste will not hold, add binder, not liquid.

Be wary of banana and apple purée. A mashed-banana bar is not in the same category as a date bar: fresh banana is around 75 % water. Those versions keep for a few days in the fridge, not two weeks in a tin.

Wrap individually for the freezer, with baking paper between layers, or the bars weld into a block. UK Food Standards Agency guidance puts the fridge between 0 and 5 °C and the freezer at around -18 °C, and reminds you to cool food before putting it in rather than placing it in warm.

In practice, a well pressed, properly dry date bar keeps a week to ten days in an airtight box in the fridge, and two months in the freezer. A bar built on fresh fruit keeps three or four days chilled. The warning sign is not the date but the look: if a surface that was matt turns damp or tacky, moisture has migrated and the bar is going off.

Five safety points that almost never get mentioned

No honey before one year old, ever. The NHS is explicit: honey can contain bacteria that produce toxins in an infant’s gut and cause infant botulism, a very serious illness. No honey before twelve months, cooked or not, not even as a trace in a bar. Use date paste for anything aimed at very young children, bearing in mind that below one year no free sugars are recommended at all.

No whole nuts before five, either. The NHS advises against whole nuts for under-fives because of the choking risk. Finely chopped or as a butter they are fine from the start of weaning at around six months, provided the butter is spread on a food rather than given off a spoon.

Linseed contains cyanogenic glycosides. EFSA established in 2019 an acute reference dose of 20 micrograms of cyanide per kilo of body weight, applicable regardless of the dietary source. For a 65 kg adult that is 1.3 mg of cyanide. The quantities in the recipes above, 10 g of ground linseed spread over ten bars, stay a long way below that. The point matters to people eating several spoonfuls of ground linseed a day on top of the bars, not to someone putting one spoonful in a batch.

Chia swells, and it swells wherever it happens to be. Chia seeds absorb several times their mass in water. In a bar they are hydrated by the binder and the process finishes in the fridge. The problem arises when dry seeds are swallowed with little liquid. Always let the mixture rest for at least two hours before cutting: that is also how long the chia takes to finish absorbing, and it is what gives the bar its final structure.

Dried fruit and cocoa are regulated for good reasons. Regulation (EU) 2023/915 sets maximum aflatoxin levels for dried figs, at 6.0 micrograms per kilo for aflatoxin B1 and 10.0 for the sum, and for almonds and hazelnuts destined for sorting. Ochratoxin A is capped at 8.0 micrograms per kilo for dried vine fruits and dried figs, and at 3.0 for cocoa powder, which is also limited to 0.60 mg of cadmium per kilo when sold to the final consumer. These limits apply to placing on the market, so to what you buy, not to your kitchen. They simply justify buying dried fruit through a channel that tests, and discarding without hesitation any dried fruit showing visible mould or a musty smell, rather than cutting away the affected part.

A word on allergens, if you give them away

Homemade bars are a common gift, and that is where the issue arises. A bar typically contains nuts, peanuts, sesame and gluten-containing cereals, four of the main allergen families in Annex 6 of the Swiss ordinance. Oats deserve a specific mention: they count among gluten-containing cereals under that ordinance, and cross-contamination with wheat during growing and milling is common, which makes ordinary rolled oats unsuitable for a strict gluten-free diet unless the packaging says otherwise.

If you hand your bars around, just say what is in them. Nobody expects a label, everybody appreciates a sentence.

In sport: what a bar covers, and what it does not

This is the use these recipes serve best, provided you count.

The 2016 American College of Sports Medicine recommendations, revisited in a review published in the Journal of Nutrition in 2026, put useful carbohydrate intake at up to 90 g an hour for efforts lasting more than 2.5 to 3 hours, from glucose-fructose blends. That review notes that recent research supports raising the ceiling to 120 g an hour in trained participants, while the 120 to 200 g an hour observed in the field among some professionals is not substantiated by the available data.

A bar from these recipes supplies between 17.8 and 18.5 g of carbohydrate. Sustaining 60 g an hour on a long ride would therefore mean chewing three bars an hour, which is realistic for neither the jaw nor the stomach. A dense raw bar is food for hiking, for a moderate bike ride, for a stop in the mountains. It is not a high-cadence fuelling product, and shop gels exist precisely because this format is hard to swallow at intensity.

On glycaemic index, the data exist but they are less clear-cut than the usual story. A trial in 19 healthy subjects published in the Annals of Saudi Medicine in 2016 measured the glycaemic index of 17 date varieties: mean 55.2, range 42.8 to 74.6, with no statistically significant difference between varieties, but glycaemic loads ranging from 8.5 to 24 which did differ significantly. In other words, dates are a medium-GI food, and quantity does the work, not variety.

The calorie count for nuts is wrong, and that is in your favour

One counter-intuitive detail is worth knowing when you calculate what a bar is worth.

The energy values printed on packaging are calculated with Atwater factors: four kilocalories per gram of carbohydrate and protein, nine per gram of fat. Those factors are an average established more than a century ago, and they assume the food is fully digested. A trial published in the American Journal of Clinical Nutrition in 2012, in 18 healthy adults given 0, 42 or 84 g of almonds a day with complete urine and faecal collection, measured the metabolisable energy of almonds at 4.6 kcal per gram, against 6.0 to 6.1 kcal per gram by Atwater factors. An overestimate of 32 %.

The reason is mechanical: the almond cell wall resists chewing and digestion, and some of the fat never leaves the cell. The per-bar values given above, calculated with standard factors, therefore probably overstate the energy actually absorbed, all the more so because the bar contains chopped whole almonds rather than butter. That result concerns almonds; it does not transfer automatically to other nuts or to nut butters, where the cell structure is already destroyed.

Six mistakes that come up every time

Blending the dates with everything else from the start. Date paste only forms if the dates are blended alone; mixed with oats they stay in pieces and the bar will not bind.

Not pressing hard enough. This is the number one cause of crumbling bars. Press with the flat base of a glass, leaning your arm into it, until the surface is smooth.

Cutting too early. Under two hours of chilling, the fat has not set and the chia has not finished absorbing. The bar deforms under the knife.

Fixing a dry mixture with water. It shortens shelf life without improving structure. Add a date.

Adding raw chickpea or wheat flour for protein. It is the only genuinely risky move in the whole preparation, for a negligible protein gain at the dose used.

Stacking bars without separation. They weld into a block within 24 hours, fridge or freezer.

Adapting to different situations

Nut-free. Swap almonds and cashews for sunflower and pumpkin seeds, and almond butter for tahini. Structure is equivalent, the flavour earthier. Note that sesame is itself a major allergen, so this does not solve the problem for everyone.

Strictly gluten-free. You need oats explicitly labelled gluten-free, or a switch to puffed quinoa and toasted buckwheat as the base. Ordinary rolled oats will not do.

For a child. Cut the binder share and raise the dry base, to bring the sugar content down. Nuts finely ground or as a butter only below five years. No honey before one. Half a bar is a sensible portion for a four-year-old, given the 19 g daily free-sugar cap at that age.

For hiking in hot weather. Skip the cocoa-peanut version, whose peanut butter softens fast, and favour a drier base with more oats. Wrap individually: a bar that has melted and re-set in a rucksack keeps its shape but turns tacky.

If you watch saturated fat. The coconut-cashew version carries three times more than the almond one. Swapping desiccated coconut for extra oats settles it without changing the method.

Limits of the available data

The compositions given are calculated from table values for generic ingredients. Sugar content in a date varies with variety and ripeness, that of a nut butter with the brand. A 10 to 15 % spread on the per-bar figures is normal.

The glycaemic index data on dates concern dates eaten alone, at a dose of 50 g of available carbohydrate, in healthy subjects. A date blended into a fatty, fibrous matrix does not behave the same way, and no published data describe the glycaemic response to these particular bars.

The free sugar, fibre and saturated fat figures cited here are British. Switzerland publishes no equivalent numerical cap for free sugars; the Swiss thresholds quoted concern labelling, not recommended intakes.

Finally, the cost gap between homemade and shop-bought is not quantified here, because Swiss retail prices for dried fruit and nut butters vary too much between retailers and pack sizes for a single figure to mean anything.

Common questions

Do I really need a food processor? Not for date paste: warm, soft dates mash with a fork, and a sharp knife does the rest. A processor saves time and gives a more even texture, nothing more.

My dates are dry and hard, what now? Soak them ten minutes in hot water, then drain thoroughly and pat dry. Do not tip the soaking water into the mixture.

Can I replace dates with maple syrup? Yes for flavour, no for structure. Maple syrup, at 62.6 g of sugars per 100 g according to Ciqual, brings sugar and water but no fibre and no solids: the bar stays soft. It also moves the preparation into the added-sugar category, which rules out the “no added sugars” wording.

How long does a bar survive in a rucksack? A day without trouble below 25 °C. Above that the fat softens and the bar deforms, without becoming unsafe, since its low water content protects it.

Are these bars a breakfast? They fill a gap, but 140 kcal and 4 g of protein do not make a meal. Pair one with a yoghurt or a fortified plant drink rather than eating it alone.

Can I freeze them after cutting? Yes, individually wrapped, for around two months. The texture after thawing is very close to the original, unlike fresh-fruit bars which weep water.

Is a homemade bar better than a shop one? It is denser in nuts, higher in fibre and free of additives. It is not lower in sugar. The real gain is control of the ingredient list, not an across-the-board nutritional advantage.

To go further, the long-keeping raw bars for hiking cover drying and packing, and dehydrating plant-based meals extends the same water-activity logic. On ingredients, see the differences between flax, chia and hemp, the guide to pumpkin, sunflower and sesame seeds and the breakdown of natural sugar alternatives and GI. On nutrition, the complete plant protein guide places a bar accurately within daily intake, and vegetarian diets for endurance sport details carbohydrate needs. For cooking around them, the whole grain cooking guide, the raw date and cocoa desserts and the allergen-free cooking guide are the useful companions.
