Preheat the oven to 180 Celsius / 356 Fahrenheit.
To make the cake, chop or mash you avocado and blend it in a food processor with the eggs, almond milk, coconut cream, cocoa powder and vanilla extract. Blend for a few minutes until absolutely smooth and there are no lumps left. If necessary, scrape down the sides with a spatula in between.
Now add the almond flour, baking powder and sweetener and blend until well-combined.
Line a 7 inch springform with parchment paper and grease the sides. Fill in the batter and bake for about 30-35 minutes until the top is firm.
While the cake is cooling, prepare the frosting: Melt the chocolate in a double boiler or in the microwave (30 second bursts). Blend the avocado, sweetener, cocoa powder and almond milk in a food processor until absolutely smooth. Last, add the melted chocolate and blend until well-combined.
Spread over the completely cooled cake and serve.
