I grew up eating Pure protein bars and Quest protein bars, but not anymore. Sick and tired of forking out tons of money for a store-bought protein bar, I opted to make my own and feel SO much better about it… and my wallet is thanking me too!

This protein bar recipe combines two of my favorite no bake snacks: protein balls and oatmeal energy balls. I love packing them in my bag for a quick and healthy snack between meals.

Why I love this recipe

  • Made with just 4 simple 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!

Ingredients needed

  • Protein Powder. Any protein powder works, including whey protein powder, casein protein powder, and pea protein powder. 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. Sweeten the bars without adding refined sugar. I’ve also made these with honey and agave nectar which works well.
  • 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

I’ve included step-by-step photos below to make this recipe easy to follow at home. For the full printable recipe instructions and ingredient quantities, scroll to the recipe card at the bottom of this post.

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.

Recipe 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 flour 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 fridge in an airtight container. They will keep well for up to two weeks.

To freeze: Place the bars in a ziplock bag and store them in the freezer for up to 6 months.

Frequently Asked Questions

Do protein bars make you gain weight?

Homemade protein bars are great for weight management or a weight loss diet as they use wholesome and healthy ingredients and have around 150 calories.

Is it healthy to have a protein bar every day?

Solely eating multiple protein bars can have negative side effects, especially if you have an intolerance to protein powder ingredients. 

However, enjoying 1-2 protein bars per day as a snack can keep you satisfied and fuller for longer.

Is eating a protein bar the same as drinking a protein shake?

Most protein shake recipes have few carbs or fat in it, which won’t keep you as satisfied as a protein bar. Shakes are great after a workout, especially if you intend to eat a solid meal soon after.

Homemade Protein Bars (4 Ingredients!)

4.99 from 982 votes
These homemade protein bars need just four ingredients to make and are healthier and better tasting than anything store bought! Watch how I make this in my kitchen in the video below!
Servings: 12 servings
Prep: 5 minutes
Cook: 1 minute
Total: 6 minutes




  • Line a deep pan with parchment paper and set aside. For thicker bars, use an 8 x 8-inch pan. For thinner bars, use any size bigger. 
  • In a large mixing bowl, add your dry ingredients and mix well. 
  • In a small mixing bowl, melt your peanut butter with sticky sweetener until combined. Add to dry ingredients and mix until fully combined. 
  • Transfer protein bar batter into the lined baking dish and press firmly in place. Refrigerate or freeze until firm. Once firm, cut into bars and cover in optional chocolate and enjoy! 


* I prefer using casein, brown rice, or paleo protein powder. I never recommend whey as the texture is incredibly sticky and doesn’t form well. 
If the batter is too thick/crumbly, add water/milk until a firm batter remains. 
TO STORE: Store at room temperature in an airtight container. Protein bars store well in the refrigerator, too! Let them sit at room temperature for several minutes before enjoying. 
TO FREEZE: Freeze in a sealable container for up to 6 months.

    Hi, can you please update the metric. I have no idea how much “2 scoops” of protein powder would weigh, because ours comes in a bag, without a scoop.

    Hi Arman, thanks for sharing your recipe!
    But I’m a bit confused by seemingly contradicting instructions on whether or not it’s possible to use whey protein for these bars.
    Under the header Ingredients Needed you write “Any protein powder works, including whey protein powder…”, but in the first note right under the recipe you say “I prefer using casein, brown rice, or paleo protein powder. I never recommend whey as the texture is incredibly sticky and doesn’t form well.”

    Hope you can clear this up for me!

    Thanks and have a nice day!

    1. Hi! I’m so sorry, I’ll fix it. I would avoid whey, it just is too thin and sometimes will yield wet protein bars 🙂

    I love all of the granola bar recipes. However, none mention sugar content. Is there a way to figure that out??

    These are amazing! I made a batch last weekend in an 8 x 8 dish. I froze half–I love going two weeks without having to worry about lunch! Since chocolate gives me migraines, I skipped the chips, but the only other sub was honey in place of maple syrup. Well, I added dried coconut, yum! I heated the honey in the microwave and was able to use less that way because it blends it so easily. My only problem is lack of self control–I need to bring 5 pieces on Monday, not half the dish because I can’t stop nibbling! I plan to share this with a friend because she buys Kind bars and boy, are those expensive. Anyway, this woman is a fan of Big Man’s World!
