- STEP 1
In the top of a double boiler, combine butter, sugar and cocoa powder. Stir occasionally until melted and smooth. Beat in the egg, stirring until thick, 2 to 3 minutes. Remove from heat and mix in the biscuit crumbs, coconut and almonds (if adding). Press into the bottom of an ungreased 8x8 inch pan
- STEP 2
For the middle layer, cream together butter, cream and custard powder until light and fluffy. Mix in the icing sugar until smooth. Spread over the bottom layer in the pan. Chill in fridge.
- STEP 3
While the second layer is chilling, melt the chocolate and butter together in the top of a double boiler. Spread over the chilled bars and place in fridge. Let the chocolate just set/harden and cut into squares, return to the fridge to set fully (if you allow the chocolate to completely set it will crack when you cut the slice up).
