Best homemade protein bars recipe
This protein bar recipe combines two of our other high protein snacks: protein balls and oatmeal energy balls. I love packing them in my bag for a quick and healthy snack between meals, and you’ll often find them in my car, too!
- Made with just 4 ingredients, they take minutes to prepare. We try to make a batch at least once a week, so we always have some on hand. However, they taste so good, they rarely last that long.
- They use wholesome ingredients, like coconut flour, and are sweetened with just a touch of maple syrup.
- Each bar packs in over 21 grams of protein.
- They are great to enjoy between meals as they always keep hunger at bay!
Homemade protein bars are simple creatures: they use pantry staple ingredients with the addition of protein powder. Here is what you’ll need:
- Protein Powder. Any protein powder works, including whey protein, casein protein, and brown rice protein.
Ingredient tip
For flavored protein bars, why not try a flavored protein powder? Chocolate, peanut butter, and cinnamon roll are all fabulous flavors.
- Coconut Flour. This helps hold the protein bars together while ensuring they have a soft and doughy texture.
- Peanut Butter. Smooth and drippy peanut butter, with no added sugar. You can also use almond butter.
- Maple Syrup. Sweetens the bars without adding refined sugar.
- Chocolate Chips. To cover the protein bars with! To keep these as plain peanut butter protein bars, you can omit the chocolate.
How to make homemade protein bars
Step 1- Mix the ingredients
Add all the ingredients in a mixing bowl and mix until combined. Fold through the chocolate chips.
Step 2- Let the bars set
Transfer the mix into a lined pan and press down until smooth on top. Refrigerate for an hour.
Step 3- Slice
Using a slightly wet knife, slice into protein bars, then serve.

Dietary swaps and substitutions
This protein bar recipe is very forgiving and it’s easy to make them compliant to a plethora of diets out there with a few simple swaps.
- Cut the sugar. Replace the maple syrup with a sugar free maple syrup.
- Replace the coconut flour. Either oat or almond flour can be used instead. You may need to add a little extra flour to compensate for the extra moisture.
- Make them peanut-free. Almond butter or cashew butter are both great nut butters to use. You could make chocolate protein bars by using healthy Nutella.
- Make them nut-free. Tahini or sunflower seed butter have an almost identical texture to nut butter.
- Vegan and/or gluten free. Make vegan protein bars instead.
Storage instructions
To store: Homemade protein bars are best stored in the refrigerator, covered. They will keep well for up to two weeks.

2 questions
1. Can I use egg-white protein powder?
1. If I’d like to reduce the amount of fat per serving, how much PB can I cut?(Or what could I use instead of PB?)
Thanks!
Yes, egg white powder should work! Several readers have tried PB2 (Peanut flour) successfully.
I used PB2 and it worked fine! I make mine into balls and freeze!😍
I’m thinking of making this and wonder if it work if I used PB2 instead of peanut butter.
You can try and see.
I made them and shared at work and everyone loved them.
