Preheat oven to 375 degrees F.
Line a 9 inch spring form pan with parchment paper.
Whisk the dry ingredients together; coconut flour, baking powder and 1/2 cup sweetener together in a large bowl. Set aside.
Place the egg whites into a stand mixer or mixing bowl and use an electric mixer, with the remaining sweetener and blend until stiff peaks form.
In another bowl whisk the egg yolks, butter, vanilla extract and vanilla stevia.
Fold the coconut flour mixture into the egg yolk mixture.
Gently fold in the stiffened egg whites in small batches into the coconut flour until a smooth batter forms.
Pour batter into pan and bake for 25-30 minutes until golden brown. Set aside to cool for about 20 minutes, do not remove from the pan.
Take a skewer stick and poke holes in cake about half way, but not all the way to the bottom of the pan so the cream doesn't leak out.
In another medium bowl whisk together the coconut milk, Half & Half, heavy cream and optional brandy.
Pour this milk mixture over the cake into all the holes. Allow to stand for 30 minutes.
For best results, cover with plastic wrap and refrigerate for at least one hour then remove the sides of the spring form pan before frosting.
Frost before serving and enjoy with fresh berries of desired!
Store leftovers covered in the fridge or an airtight container for up to 7 days.
