Preheat oven to 180 Degrees Celsius.
Melt butter and sugar over moderate heat in a large pot until sugar is dissolved. Turn off the heat.
Add the ground almonds, cocoa powder and vanilla essence and mix well.
Add the eggs and chocolate and mix until well combined and smooth.
Pour into a greased and lined 20 cm loose- bottom cake tin.
Bake for 25 minutes. Turn oven off and leave for 30 minutes.
Remove from oven and cool completely.
Tip: Try baking the day before. Cool, then cover with cling wrap.
Once cooled, use a sharp knife to gently loosen the sides and remove from the tin.
To serve: Generously spread creme fraiche onto the torte and top with loads of fresh berries.
Optional: Sprinkle with icing sugar for funsies.
