What You Will Need

  • Almond Flour - 1 cup of finely ground almond flour. I used the Organic Fine Almond Flour by Prozis. Code KATIE10 for 10% off!
  • Vanilla Protein Powder - 45 grams, for some vanilla flavor and protein! My personal favorite is the natural vanilla whey isolate by the brand Prozis. You can actually use the code “KATIE10″ for 10% off at Prozis!
  • Salt - 1/4 teaspoon, for flavor. You may not need additional salt if your peanut butter is salty already.
  • Baking Soda - 1/2 teaspoon, to make the cake rise
  • Egg- 1 large egg.
  • Bananas - You will need 2 medium rips mashed bananas.
  • Peanut Butter - 2/3 cup of creamy peanut butter. I used the Caramel Peanut Butter by Prozis. Y'all...this is the best peanut butter ever. You can use my discount code KATIE10 for 10% off on this as well!
  • Maple Syrup - 1/4 cup of sugar free maple syrup. My favorite is by the brand Lakanto, because it does not contain sucralose and is sweetened with monk fruit! You can find it on Amazon here.
  • Vanilla Extract - 1/2 teaspoon, for flavor.

How To Make It

  1. Preheat your oven to 350°F. Line an 8x8 inch glass baking dish with parchment paper.
  2. In a large bowl, mash the bananas. Add in the egg, syrup, peanut butter, and vanilla extract. Mix until creamy and there are very little to no lumps.
  3. Add in the almond flour, salt, protein powder, and baking soda.
  4. Pour the batter into the prepared baking dish. Bake for 25 minutes or until set but still slightly gooey in the center (Leave it a little gooey because it will set in a lot, I promise. Let cool completely before slicing. Enjoy!

How To Store

Do You Eat These Warm or Cold?

These are honestly amazing both ways. Personally, I like to warm them up a little in the microwave.
