Warm your oven to 325°F (165°C).

Crack the eggs into a big bowl and whisk them well. Toss in the granulated Monk fruit sweetener, vanilla extract, apple cider vinegar and baking powder. Give it another good whisk to mix everything.

Drop in the softened butter and blend it all together (this works better with an electric mixer). Heat the sugar-free dark chocolate in the microwave for about a minute, pour it in, and mix everything for a couple minutes until smooth.

Now dump in your almond flour and coconut flour. Switch to a spatula for mixing since the batter will get pretty thick.

Oil up an 8-inch round cake pan and pour your batter in. Pop it in the oven for 35-40 minutes. You'll know it's done when you stick a toothpick in the middle and it comes out clean. Let it cool all the way before you top it.

For your chocolate mousse, pour the heavy cream into a medium bowl (it helps if the bowl is cold). Beat it with an electric mixer until you see soft peaks. Then gently mix in the powdered Monk fruit sweetener and cocoa powder with a spatula. Don't use the electric mixer here or you'll ruin it.

After your cake has totally cooled down, slather the chocolate mousse all over the top and sides. You can keep what's left in the fridge for up to 4 days.
