Homemade Protein Bars: Three No-Bake Recipes

Quick answer

Mix 1 and a half cups of rolled oats, half a cup of peanut butter and a third of a cup of honey, press the dough into a pan and cut 12 bars. By USDA values each bar holds about 130 kcal and 4 g of protein before the protein powder, which adds whatever its label states.^1,2,3

Key facts

The peanut butter and honey bars hold about 130 kcal and 4 g of protein each, before the powder. The date and almond butter bars hold about 155 kcal and 4 g. The seed butter and maple bars hold about 125 kcal and 3 g.^{1,2,3,4,5,6,7}
Honey counts as an added sugar on a Nutrition Facts label. The honey in the first recipe comes to about 8 g a bar, roughly 15% of the 50 g Daily Value for added sugars.^3,8,9
FDA names nine major food allergens, including peanuts, tree nuts, sesame, milk and soybeans, and labels must name the source of each one.¹⁰
FDA says never to eat or taste raw flour, so none of these no-bake bars uses it.¹¹
MedlinePlus advises not letting babies eat honey, so leave it out of anything a baby might taste.¹²

Homemade protein bars recipe with protein powder

This is the base recipe. The oats, peanut butter and honey in the whole pan come to about 1,575 kcal, which is about 130 kcal and 4 g of protein per bar when cut into 12, before the powder is counted. The powder's own label gives the rest.^1,2,3

1 and a half cups (121 g) rolled oats¹
Half a cup (129 g) peanut butter²
A third of a cup (113 g) honey³
2 scoops protein powder, vanilla or unflavored, with the scoop size and protein per scoop read from the label
2 to 4 tablespoons milk, only if the dough is too dry, and a pinch of salt

Warm the peanut butter and honey in a small pan or the microwave until pourable, and stir.
Stir in the powder and the oats until you have a thick, sticky dough. Add milk a spoonful at a time only if it will not come together.
Press the dough firmly into a lined 8 inch pan with the back of a spoon.
Chill for an hour, lift out with the paper and cut into 12 bars.

Protein bars homemade without protein powder

Dates act as the binder here, and almond butter and oats carry the protein. Twelve pitted Medjool dates (288 g), 1 cup (81 g) of rolled oats and half a cup (125 g) of almond butter make 12 bars of about 155 kcal and 4 g of protein each by USDA values. That is less protein than the powder recipe shows, so we call these oat and nut bars rather than protein bars.^1,4,5

Soak the dates in hot water for 10 minutes if they are firm, then drain and pit them.
Blend the dates and almond butter in a food processor until they form a paste.
Add the oats and pulse until the dough sticks together when pinched.
Press into a lined pan, chill and cut into 12.

Protein bars homemade without peanut butter

Any nut or seed butter works in the same amounts. For a recipe with no peanuts or tree nuts, use 1 and a half cups (121 g) of rolled oats, half a cup (128 g) of sunflower seed butter and a third of a cup (105 g) of maple syrup. That makes 12 bars of about 125 kcal and 3 g of protein each by USDA values.^1,6,7

Binders and sweeteners compared, by USDA values^{2,3,4,5,6,7,13}
Ingredient	Amount	Calories	Protein
Peanut butter	2 tablespoons (32 g)	190 kcal	7.1 g
Almond butter	2 tablespoons (32 g)	195 kcal	6.7 g
Sunflower seed butter	2 tablespoons (32 g)	195 kcal	5.5 g
Tahini	2 tablespoons (30 g)	180 kcal	5.1 g
Honey	1 tablespoon (21 g)	65 kcal	0.1 g
Maple syrup	1 tablespoon (20 g)	50 kcal	0 g
Medjool date, pitted	1 date (24 g)	65 kcal	0.4 g

Tahini is made from sesame, which FDA has listed as the ninth major food allergen since January 1, 2023. Sunflower seeds are not among the nine, but cross-contact statements on a label still matter, so read it.¹⁰

Protein bars homemade low calorie: where the calories come from

Nearly all the energy in these bars comes from the nut butter and the sweetener, as the table shows. The simplest change is a smaller bar. Cutting the first recipe into 16 pieces instead of 12 brings each one to about 100 kcal and 3 g of protein, before the powder.^1,2,3

Using less binder makes a crumbly bar, so we would change the size first. Whatever you pick, the numbers above are for the dough only.

Homemade protein bars healthy? What the numbers say

We do not rate recipes as healthy or not, because that depends on the person and the rest of the day. We can give the figures that people ask about. In the first recipe the honey comes to about 8 g of sugar a bar, and FDA says honey counts as an added sugar on a label. Against the 50 g Daily Value for added sugars that is about 15%, and FDA's general guide calls 5% or less low and 20% or more high.^3,8,9

The maple recipe has about 5 g of sugar from the syrup per bar. The date recipe has no added sweetener, since the sugar comes from whole fruit, but it holds about 16 g of sugar per bar in all.^4,7

How should you store homemade protein bars?

We found no official shelf life for homemade bars. Without raw egg, raw flour or fresh dairy they are a different case from egg dishes, but milk added to the dough makes the batch perishable. FDA says to refrigerate perishable food within 2 hours, to keep the refrigerator at 40°F or below and the freezer at 0°F or below.¹⁴

One way to handle them is to wrap each bar, keep a few in the refrigerator and freeze the rest. Do not add flour to a no-bake bar, because FDA says never to eat raw flour and that milling does not kill bacteria on it.¹¹

Homemade protein bars for kids, allergies and who should check first

Peanuts, tree nuts, sesame, milk and soybeans are among the nine major food allergens FDA lists, and whey comes from milk. FDA says labels must name the source of each major allergen, with whey (milk) as one of its examples. Read every label, the powder's included.¹⁰

Honey should not be given to babies. MedlinePlus advises not letting babies eat it, so leave it out of anything a baby might taste or share.¹²

If anyone eating the bars has a food allergy, ask their doctor before trying a new nut or seed butter. Ask your child's doctor before giving protein powder to anyone under 18. Ask your own doctor before using it if you have kidney disease or have been told to limit protein, or if you are pregnant or nursing.¹⁵

Questions people ask

How do I make homemade protein bars with protein powder?

Can I make homemade protein bars without protein powder?

Yes. The date and almond butter bars hold about 4 g of protein each by USDA values, so they are oat and nut bars, with less protein than a powder recipe.^1,4,5

What can I use for homemade protein bars without peanut butter?

Almond butter, sunflower seed butter or tahini work in the same amounts. Tahini is sesame, one of the nine major allergens FDA lists, and sunflower seeds are not.¹⁰

Are homemade protein bars healthy?

We do not rate recipes. The honey in the first recipe is about 8 g of added sugar a bar, roughly 15% of the 50 g Daily Value, and honey counts as an added sugar on a label.^3,8,9

How can I make homemade protein bars lower in calories?

Cut the same pan into smaller bars. Sixteen bars from the first recipe come to about 100 kcal each before the powder, since the nut butter and honey carry most of the calories.^1,2,3

Are there homemade protein bars for kids?

Bars can leave the powder out, as the date and almond butter recipe does. Ask your child's doctor before using protein powder for anyone under 18, keep honey away from babies, and check every label for allergens. The seed butter and maple recipe has no peanuts or tree nuts.^10,12,15
