I know I put this recipe on before, but I have changed it a little since then.
4 cups Powdered Sugar
1/4 to 1/2 cup cocoa powder
1 cube of butter cut in pieces (not margarine)
1/4 cup milk
1 tsp vanilla
1/2 to 1 cup peanut butter
peppermint pieces (optional)
Mix only the first 4 ingredients in a microwave safe bowl. DO NOT STIR. Microwave on HIGH for 2 minutes. Remove from microwave and mix until smooth. Using an electric mixer is the best way to do this without leaving lumps of sugar.
Add vanilla, peanut butter and nuts (if using them) and mix until well blended. The mixture should be thick and able to hold it's shape. If it is not pulling cleanly away from the sides of the bowl, add a little more powdered sugar and mix until it is thick enough.
Pour into a buttered dish. Put into the fridge to set and cool. Make sure to lick the beaters and the bowl; you won't want to waste any of this. Cut into pieces and enjoy.
Make this once or twice before you give it as a gift or anything, just to make sure you get the right consistancy. It will be a hardship, I know!
