Easy Fudge (Louise)

3 cups Icing sugar
1/2 cup cocoa
1/4 cup evaporated milk
1 cup hard margarine or butter cut into small chunks
2 tsp vanilla
nutts (optional) 3/4 cup

Put icing sugar and cocoa into and ungreased casserole dish.
Add evaporated milk and margarine, do not stir.
Cook uncovered on high in microwave for 3 minutes(depending how how your microwave is)just until butter is melted.
Add vanilla. Beat with electric mixture, put in an 8by8 pan or pie plate and stick it in the freezer till you want to eat it.
Last time I put it in a pie plate and just cut it up like pie, worked out well. This is a great last minute dessert for unexpected company!!
ENJOY!!!!
