Chocolate sponge cake
Swiss Butter cream
Assemble Chocolate cake
Place a ¼ of the Swiss butter cream into a piping bag. Place the first sponge on a cake board, (this is to move cake easier from work top to a fridge). Pipe dam around sponge, to prevent the chocolate mousse from leaking. Place chocolate mousse in the centre.
Place second cake on top and chill in the fridge for 10 minutes.
Spread the remaining Swiss butter cream, thinly on the top and side of the cake and chill for 10 minutes. Repeat and chill for further 10 minutes
Place the cake on a wire rack over a baking tray. This is to collect excess chocolate glaze.
Pour the chocolate glaze over the cake, starting from the edge of the cake then to the centre.
