Place the eggs into a large bowl and beat them. Add the granulated Monk fruit sweetener, vanilla extract, apple cider vinegar and baking powder. Whisk again to combine.

Add softened butter to the mixture and mix to combine (an electric mixer works best here). Melt the sugar-free dark chocolate in the microwave for 45-60 seconds, then add it to the bowl. Mix for a few minutes until you have a smooth batter.

Add the almond flour and coconut flour to the bowl and stir to combine. Use a spatula for this step as the batter will become thicker.

Grease an 8-inch round cake pan and transfer the batter into it. Bake for 35-40 minutes or until a toothpick inserted in the center comes out clean. Allow to cool completely before frosting.

For the chocolate mousse, add the heavy cream to a medium bowl (chilling the bowl beforehand helps) and whip it with an electric mixer until soft peaks form. Add the powdered Monk fruit sweetener and cocoa powder and gently fold in with a spatula to combine. Avoid using the electric mixer at this stage to prevent over-whipping.

Once the cake has completely cooled, spread the chocolate mousse on the top and sides of the cake. Store leftovers in the refrigerator for up to 4 days.
