Preheat the oven to 200 ºC.
Chop the butter and chocolate into a bowl and melt gently in a microwave. Add the eggs, almond flour, SteviaSweet Granulated and orange peel. Mix until smooth.
Place baking paper on the bottom of a spring form pan (20 - 22 cm) and butter the sides. Pour the batter into the tin and bake for 25-30 minutes. Leave the cake to cool down.
Decorate the cake just before serving. Whip the cream with vanilla and spread on the cake. Sprinkle with cocoa powder.
