Easy Chocolate Fudge

My kids were begging for a treat so last night I whipped up some fudge. This is not the type you need a candy thermometer for; no long cooking and stirring and beating times. It's super simple and makes a very rich chocolatey fudge. I can't remember where I first found the recipe but I'm going to share it. No pictures because--it didn't last long enough!

Ingredients:
1 500g. package confectioner's sugar
.5 cup cocoa powder
.25 cup milk
.5 cup butter/margarine
1 teaspoon vanilla
.5 cup chopped walnuts (optional)

Method:
Sift together sugar and cocoa in large bowl (the sifting is important to avoid lumpy fudge). Add milk and butter. Do not stir. Microwave on high until butter is melted (about 2 - 2.5 minutes). Stir until smooth. Stir in vanilla and nuts. Spread in well-greased 8"x8" pan. Refrigerate until set (about an hour).

It's best kept in the refrigerator and served chilled, so not very good for bake sales, etc. But delicious!
