For preparing the chocolate soaking syrup, heat the water, icing sugar and cocoa powder until boiling and slightly thick for 2-3 minutes. When thick add chopped chocolate, and whisk rigorously to remove lumps and melt the chocolate. Pour this warm syrup to soak a decadent cake or use as a dip.

If you are pouring on the cake, then follow this step - Poke tiny holes in the cake using a toothpick or skewer. Pour the warm syrup in still warm cake allowing it to be absorbed in whole cake. Allow it to set and absorb as much as possible before topping with cream layer or serving just as is.
