Break the chocolate into pieces and chop finely. Pour 1 cup of cream into a bowl. Wash the cream cup, dry it and use it as a measuring cup. Whisk eggs and sugar with the whisk of the hand mixer for 8-10 minutes until white and creamy. Sift flour on top and fold in. Fold in cream from the bowl and chocolate. Pour the dough into a greased springform pan (26 cm Ø) sprinkled with breadcrumbs.
Bake in the preheated oven (electric cooker: 175 °C/ convection oven: 150 °C/ gas: level 2) for about 40 minutes. Leave to rest in the pan for 10 minutes, remove from the edge and allow to cool completely. Whip 2 cups of cream until stiff, adding cream firmer and bourbon vanilla sugar. Pour into a piping bag with a large perforated spout. Spray different sized tuffs onto the cake. Dust with cocoa. Decorate with mocha beans
