  • Calories: 322kcal



  • 2 1/2 cups almond flour
  • 1/2 cup whey protein powder or egg white protein powder
  • 1 tbsp baking powder
  • 1/4 tsp salt
  • 1/2 cup butter softened
  • 3/4 cup granulated Swerve Sweetener
  • 3 large eggs room temperature
  • 1 tbsp vanilla extract
  • 1/2 cup unflavored nut milk

Frosting and Garnish

  • 1 1/4 recipe Swiss Meringue Buttercream
  • Sugar free sprinkles



  • Preheat the oven to 350F and grease two 8 inch round metal baking pans well. Line the bottoms with parchment paper and grease the parchment.
  • In a medium bowl, whisk together the almond flour, protein powder, baking powder, and salt.
  • In a large bowl, beat the butter with the sweetener until lightened and fluffy, about 2 minutes. Beat in the eggs one at a time until well incorporated, then beat in the vanilla extract.
  • Add the flour mixture in two additions, alternating with the nut milk. Divide the batter among the prepared baking pans and spread to the edges.
  • Bake 20 to 25 minutes, until golden brown around the edges and the tops are just firm to the tough.
  • Remove and let cool in the pans 30 minutes, then run a sharp knife around the edges and flip out onto wire racks to cool completely.

Frosting and Garnish:

  • Prepare the frosting according to the directions. Reserve about 1/2 to 2/3 cup of the frosting for piping decoratively.
  • Place one layer of cake on a cake stand or plate. Spread the top with one-third of the remaining frosting. Place the second layer on top and spread the top with another third of the frosting. Spread the sides with the final third.
  • Use the reserved frosting to pipe rosettes or stars around the edge of the top of the cake. Sprinkle the top with 1 tbsp sugar free sprinkles.
  • To add sprinkles to the side of the cake: Set the cake plate on a clean counter. Pour sprinkles into your hand and gently press around the bottom 1 to 2 inches, letting any that don’t stick fall onto the counter. Turn the cake as you press more into the bottom.
