Want to eat a cookie that’s healthy, but that doesn’t taste healthy? You’ve come to the right place! I’m excited to introduce you to –> Peanut Butter Protein Cookies! 

Are protein cookies healthy?

The big question the internet is asking…are protein cookies actually healthy? Truth is, a lot of protein cookies that you can buy in the store are not necessarily healthy.

Why? Well, they are loaded with ingredients you can’t pronounce and sometimes even made with cane sugar!

What to look for

Make sure you look for a protein cookie recipe that…

  • Has few ingredients
  • Is refined-sugar free
  • Higher than 6g protein/serving

Note: This protein cookie recipe is smaller than most store-bought protein cookies. For a better comparison, you can use the nutritional information of 2 cookies.

3 forms of protein!

Not only do you get protein from the protein powder, but also from 2 other ingredients in this recipe.

Peanut Butter: not only is peanut butter considered a fat, but it all packs in the protein! Per 2 tablespoons, there is 8g protein. 

Protein Powder: We tested this recipe with both vegan protein powder as well as whey-based protein powder. It works great for both! In most protein powders, you’re looking at around 20+g protein/1/2 cup.

Best Protein Powders

Check out our top protein powder recommendations for baking, smoothies, and everything in between.

Eggs: Eggs are an essential part of this recipe as they help bind each cookie together. There’s also a substantial amount of protein added from them too. 1 large egg has 6g protein.

More on Protein Powder

Lucky for you, we have an entire post on Fit Foodie Finds called A Guide to the Best Protein Powder where we reviewed our favorite protein powders!

The protein powder you choose for this recipe is extremely important because it definitely adds flavor and sweetness to these cookies. Our 2 favorites are:

You can always use unflavored protein powder to really get the peanut/buttery taste OR swap it in for a chocolate protein powder.

Coconut Sugar

The 4th ingredient in this recipe is coconut sugar! We love baking with coconut sugar because it’s all-natural and not as sweet as a lot of other sugars on the market.

We have NOT tested this recipe with any other sugars such as cane, stevia, or brown sugar. If anything, we recommend swapping it 1:1 with brown sugar. Let us know if you have any modifications in the comments.

Storage

We recommend storing these cookies in the freezer for the best and longest results.

How to freeze: Place cooled cookies on a large baking sheet. Then, place in the freezer for 30 minutes. Remove and transfer into a freezer-safe gallon-size bag. Will last up to 3 months.

Ingredients 

  • 1 cup all-natural drippy peanut butter*
  • 2/3 cup coconut sugar
  • 2 large eggs
  • 1/2 cup vanilla protein powder, any kind*
  • optional: 1/3 cup chocolate chips
  • optional: coarse sea salt for topping

Instructions 

  • First, preheat oven to 350ºF and line a baking sheet with parchment paper.
  • Next, place all ingredients into a medium-sized bowl and mix. The consistency should be like cookie dough.
  • Spoon out around 1.5 to 2 tablespoons of dough into your palms and roll into a ball. Flatten between your palms to create a cookie-like shape and place on a baking sheet. Optional to add a few chocolate chips to the top of each cookie.
  • Bake at 350ºF for 8-10 minutes or until the edges begin to turn golden brown.
  • Let cool for 10-15 minutes so that the cookies can firm up.

Tips & Notes

  • Peanut butter: make sure to use an all-natural drippy peanut butter. Our favorite brands are Kirkland, Trader Joe’s, and 365.
  • Protein powder: all protein powders have their own unique taste so much sure you use one you like. Option to use a flavorless protein powder to really get the peanut buttery flavor.
  • This recipe was slightly updated on February 12, 2020. The old recipe only called for 1 large egg, but after retesting multiple times, we’ve found that 2 eggs works best! 
  • Nutrition information was calculated using Garden of Life Vanilla Protein Powder and does not include chocolate chips.

Yes, we usually have the all natural kind, but only in organic food stores. There are some supermarkets that have American brands. ๐Ÿ™‚ Peanut Butter is not a big thing in Germany….I can’t understand why ๐Ÿ˜‰
