This delicious keto birthday cake recipe is low-carb and jam-packed with all the healthy fats you want.



  • 4 ounces stevia-sweetened dark chocolate, chopped
  • 1/2 cup coconut cream
  • 2 large eggs
  • 30 drops liquid stevia
  • 2 tablespoons cacao powder
  • 1/2 cup almond flour
  • 2 teaspoon baking soda
  • 1/4 teaspoon fine salt
  • 1/2 pound of Kerry Gold butter (1 block), softened
  • 3 scoops Perfect Keto Vanilla Collagen MCT or MCT powder
  • Chocolate chips or cacao nibs


  1. Preheat oven to 350℉.
  2. In a large microwave-safe bowl, melt the chopped chocolate for 30-40 seconds until soft.
  3. Whisk until smooth, then mix in coconut cream and whisk until completely smooth.
  4. If it thickens too much, microwave it for 10 more seconds. Then continue to whisk until glassy and smooth. Once it has cooled, mix the eggs and stevia in until fully combined then set aside.
  5. Mix all of the dry ingredients in a separate bowl then fold them into the wet mix.
  6. Transfer the batter to a cake pan lined with parchment paper. Bake for 25-30 minutes.
  7. Let the cake cool before unpanning. Cut the loaf in the middle evenly as you’re going to stack them.
  8. Whip the butter and vanilla MCT powder until smooth. Add 2 tablespoons to one square, smooth it out and then stack the two cake layers. 
  9. Apply one thin coat of buttercream — this is the crumb coat. Then set it in the freezer for the butter to harden, about 20 minutes.
  10.  Remove from the freezer and finish applying the buttercream with a spatula. Garnish with chocolate chips.
