Instructions

FOR THE CAKE:

  1. Preheat the oven to 350 degrees F.

    Lightly coat three 6-inch round cake pans or two 8-inch cake pans with nonstick baking spray and line the bottom with parchment paper rounds. Set-aside.

  2. In a medium mixing bowl, whisk the almond flour, coconut flour, baking powder, baking soda and salt together. Set aside.

    In another separate large bowl, whisk together the eggs, monk fruit sweetener, coconut oil and vanilla extract. Pour in the curdled milk and mix until combined.

  5. Evenly divide the batter between the baking pans and smooth out the tops with a spatula. Bake for 19-24 minutes, or until a toothpick comes out clean.

    Allow cakes to cool in the cake pans for at least 30 minutes, then carefully remove from cake pans. Transfer to wire racks to cool completely to room temp before frosting.

FOR THE FROSTING:

  1. Using a hand mixer or in the bowl of an electric stand mixer, add the softened butter and beat on high for 3 minutes until light and fluffy. Turn the mixer to low and slowly add the powdered sweetener, vanilla extract, and almond milk and beat for 2-3 minutes until creamy and smooth. Cover and chill in the fridge until ready to frost.
