Preheat the oven to 180C/350F. Grease two 9-inch cake pan and lay a circular layer of parchment paper to the bottom, for easy removal.
In a large mixing bowl, add your eggs and softened butter, and whisk until combined and smooth. Add the vanilla extract and mix until combined.
Slowly add in the almond flour, cocoa powder, baking powder, salt, and allulose until just combined.
Transfer the cake batter into the two cake pans. Bake the cake for 27-30 minutes, or until a skewer comes out 'just' clean.
Remove from the oven and let cool in the pan completely. Once cool, place one cake on a flat surface and spread half the frosting over it. Place the second cake on top and add the remaining frosting.
