For the cream
For the layers:
For the cream, blend all ingredients together in a bowl until combined, and set aside.
Add a little rum to a cup of coffee and dunk the biscotti in it; lay these then in a glass or small dish. Spread a layer of cream over the biscotti layer. Repeat this process until the glass (I like to use a small mason jar) is full.
Dust with cocoa powder and leave to marinate overnight in the fridge.
