Keto Vanilla Birthday Cake

Step by Step Instructions

1. 1

   Preheat oven to 350°F. Line two 8-inch round cake pans with parchment and lightly grease the sides with butter. Set aside.

2. 2

   In a large bowl, whisk together almond flour, oat fiber, whey protein powder, baking powder, and salt. Set aside.

   For this step

   • 2 cups almond flour
   • 2 tablespoons oat fiber
   • 1/4 cup protein powder
   • 1 tablespoon baking powder
   • 1/2 teaspoon salt
3. 3

   In another large bowl, whisk the egg whites until slightly frothy, about 2 minutes.

   For this step

   • 6 egg whites, room temperature
4. 4

   To the egg whites, add melted butter, yogurt, sugar-free sweetener, vanilla, and milk of choice.

   For this step

   • 1/2 cup unsalted butter, melted
   • 1/3 cup plain Greek yogurt or sour cream
   • 1 cup sugar-free sweetener
   • 1 tablespoon vanilla extract
   • 1/4 cup milk of choice
5. 5

   While mixing with an electric mixer, pour the ingredients into the dry ingredients and stir until just combined.

6. 6

   Divide evenly between pans and smooth the tops. Bake at 350°F for 20-25 minutes, or until tops are set and a toothpick comes out clean. Let cool in pans 10 min, then transfer to wire racks.

7. 7

   In a large, clean bowl, beat the softened butter with an electric mixer until pale and fluffy (about 4-5 minutes). Add sweetener and beat until combined. Mix in vanilla, then gradually add heavy cream until desired consistency is reached. Frost cooled cake layers.

   For this step

   • 2 cups unsalted butter, softened
   • 1 1/2 cups powdered sugar-free sweetener
   • 1 1/2 tablespoons vanilla extract
   • 1/4 cup heavy cream
