This Gluten Free Chocolate Cake with Peanut Butter Frosting is made with clean ingredients, and is a healthier alternative to traditional boxed cake mix. A treat swap on the 21 Day Fix, dairy free, paleo, refined sugar free and grain free, too! 



For the cake (double if you are making a layer cake):

  • coconut oil or coconut oil spray
  • 2 cups blanched almond flour (I LOVE Bob’s Red Mill Super-Fine Almond Flour)
  • ¼ cup unsweetened cocoa powder
  • ½ tsp baking soda
  • ½ tsp Himalayan pink salt
  • 2 eggs
  • 2/3 cup maple syrup
  • 1/3 cup hot water
  • 1 tsp vanilla

For the Peanut Butter Frosting (double if you are making a layer cake):

  • 1/4 cup of pure maple syrup
  • 1/2 cup of coconut oil (room temp or slightly chilled)
  • 1/4 cup of PB2 or 2T of peanut butter


  1. Preheat oven to 350.
  2. Grease a round or square cake pan with coconut oil.
  3. Mix almond flour, baking soda and salt in a medium-sized bowl. In another bowl, mix hot water and cocoa powder until combined and allow to cook for a moment. Then add in maple syrup, eggs, and vanilla.
  4. Pour the wet ingredients into the dry ingredients. Mix well and pour batter into prepared pan.
  5. Bake 18-20 minutes, or until toothpick inserted comes out clean.
  6. Cool completely before frosting
  7. To make the frosting, place ingredients in a chilled glass bowl and beat using a hand mixer until it is smooth and spreadable, adding extra PB2 powder or peanut butter to taste/to desired texture. After frosting your cake, chill for best results. We love this cake cold! **If the frosting is left out at room temp, it will separate after awhile…just an FYI!
