hold on i will run downstairs and find the recipe
Ingredients:
1 pound of icing sugar
1/2 cup of cocoa
1/4 tsp of salt
1/4 cup of milk
1 tsp of vanilla extract
1/2 cup of butter/margarine
1 cup of chopped nuts (optional)
Mix all dry ingredients together in an 8x8 inch microwave safe pan (important to use this size pan) *
Add the milk and vanilla extract.
Place the chunk of butter/margarine in centre (leave as whole do not chop up)
Microwave on high for two minutes until the bottom of the dish feels warm. Stir vigourously and blend in the chopped nuts (if using)
Put in a mould/whatever and chill for 1 hour
* it says to mix the ingredients in the dish you are going to microwave it in....however, i found this was very messy so i mixed it all in a bowl first then poured it into the pan and added the butter/marg.
Time my vary depending on your microwave. Mine is 700W/Category D and iirc i needed a little longer than 2 minutes. I judged it on how the butter had melted i.e. was it easy to mix in.
