Chocolate frosting

8oz chocolate (I used milk)
8oz margarine
1 egg yolk
1 tsp vanilla
1 cup (plus lots more!) icing sugar
1 tbsp instant coffee

Melt chocolate and set aside.

Using an electric mixer beat butter until fluffy, add egg yolk and vanilla followed by icing sugar.

Melt coffee in 2 tsp hot water and add to the mix along with the chocolate.

Add as much icing sugar as needed to get correct texture, i think if you use butter above instead of margarin, less would be required.
