How To Make Keto Protein Bars

Making these bars is quite easy, it’s done in two simple steps: the peanut butter layer and then the chocolate layer.


  • Almond ButterAlmond butter is a low-carb nut butter that contains many essential amino acids. If you can’t stand almond butter, replace it with peanut butter or sunflower seed butter.
  • Protein Powder – Pick any of your favorite keto protein powders. You can use whey protein powder, collagen powder, or vegan protein powder such as pea powder or peanut powder. Just make sure it’s low enough in carbs.
  • Coconut FlourCoconut flour is a low-carb flour that is rich in fiber and contains some protein. It’s a great keto-friendly flour that can be used to make many coconut flour recipes.
  • Maple Syrup – Sugar-free maple syrup is the best option for these bars, but you can use any similar keto syrup.
  • Coconut Oil Coconut Oil contributes to hardening the peanut butter layer so it doesn’t become too soft at room temperature. It’s a great keto-friendly ingredient to add fat to your daily macros on your keto diet. You can use MCT Oil instead of regular coconut oil.

Making The Protein Bars

These keto-friendly protein bars require less than 10 minutes of preparation and about 20 minutes of freezing time.

Start the recipe by combining the base ingredients in a mixing bowl: almond butter, sugar-free maple syrup, and coconut oil.

Microwave the almond butter mixture for about 30 seconds in the microwave until it’s melted before giving it a stir with a silicone spatula.

Add the coconut flour, vanilla extract, and protein powder to the keto protein bar mixture and use the spatula to combine it fully.

Adjust the texture of the batter with either more melted coconut oil to make it a tad runnier or with more coconut flour to make it slightly dryer.

Transfer all the almond butter batter to a 9-inch x 5-inch loaf pan lined with lightly oiled parchment paper.

Flatten the top of the bars with a spatula and transfer the pan to the fridge or freezer.

Meanwhile, melt sugar-free chocolate chips with coconut oil in a mixing bowl.

You can either do so in a microwave or in a bain Marie.

When the chocolate mixture is melted, take the almond flour bars out of the fridge and pour the chocolate on the top.

Place the bars back into the fridge or freezer and let them set for 10 to 20 minutes.

Allergy Swaps

You can replace some of the keto peanut butter bars with some of the following options if you have any allergies.

  • Almond Butter: You can replace the almond butter with peanut butter or sunflower seed butter. They work just the same.
  • Coconut Flour: Swap the coconut flour for 4 times more almond flour and 2 tablespoons of protein powder.
  • Protein Powder: Protein powder is needed in this recipe, but you can pick any protein powder you like, such as grass-fed Whey Protein Powder, Collagen Powder, Pea Powder, or Peanut Powder.


These Keto Protein Bars can be eaten fresh from the fridge or frozen.

They can be stored for up to 4 days in an airtight box in the fridge or for up to 3 months in the freezer.

Thaw them in the fridge for a few hours or eat them frozen!

Frequently Asked Questions

Can I Use Powdered Erythritol?

No, the batter won’t hold together, you must use a keto syrup made for baking which means a sugar-free syrup mainly made of fiber, not water.

Look at the ingredient listed on the bottle, the first ingredient should not be water or it means the syrup is made for pancakes.

These sugar-free syrups keep no-bake keto recipes too soft.

Sugar alcohols such as erythritol or xylitol, but also other sweeteners like allulose can’t be used in this recipe.

Can I Replace Coconut Flour With Something Else?

Yes, you can replace 1 tablespoon of coconut flour with 1/4 cup of almond flour or 2 tablespoons of extra protein powder.

Note that any of these changes will also impact the bars’ texture. It can dry out the bar or make the bar more fragile.

Can You Taste The Protein Powder?

Not really, the protein powder taste is masked by the almond butter.

Are Dang Bars Healthy Options?

Dang Bars are relatively good keto-friendly bars, but they have 5 grams of net carbs per serving which is more than these bars!

Why Is Eating Protein Important On A Keto Diet?

Eating proteins is essential, in particular on a keto diet. Proteins contribute to the feeling of fullness and tend to prevent cravings.

Having keto snacks like these bars helps maintain your ketosis without feeling hungry.

Can I Just Eat Keto Protein Bars?

No, these bars are not meal replacements. Any bar sold as meal replacement bars can lead to severe deficiencies if consumed too regularly instead of a well-balanced meal.
