In the mixer, beat eggs with the melted butter at medium speed.
When this mixture is homogeneous, add cocoa powder, sweetener, vanilla extract (if needed) baking powder and almond flour. Finally, add the pumpkin puree. Mix well.
Pour this mixture into a greased baking pan. Bake for 40 minutes at 300F. When inserting a toothpick it should come out clean.
Unmold and cut the cake into triangles to form Christmas trees.
Decorating: Mix 3 tablespoons of softened cream cheese, with two tablespoons of sweetener and a few drops of food coloring (optional). Decorate the way you like it using a piping bag. Enjoy!
