Step 5: Whip and Spread
Spread the milk with a baking brush on the cake layers. Now whip the cold chocolate cream (from fridge). Next you build the cake: Take aside the bottom cake layer, it will be the top one later. Put the first cake layer on a plate and close the cake ring around it. Take one third of the whipped chocolate cream and spread it on this layer. Sprinkle the cream with half of the chocolate pieces/sprinkles. Repeat with the second layer. And finally put the last layer (the bottom layer which was set aside) on top.
