The recipe yields one single layer of cake. However, it can easily be doubled or tripled and stacked for a two or three layer cake to feed a crowd!

The cake is made with butter, eggs, sugar-free sweetener, vanilla extract, almond flour, ground flaxseeds, cocoa powder, baking powder and salt. After about 10 minutes in a 350-degree oven, it’s ready for frosting!

Whip together heavy whipping cream, cocoa powder, erythritol and vanilla extract on high in a stand mixer for about three minutes until a thick and fluffy frosting is created. Spread the frosting over the cooled cake and top with chopped sugar-free chocolate or sprinkles for a beautiful presentation. One slice of this Double Chocolate Birthday Cake contains 233 calories.
