Microwave on high for 2 1/2 minutes. Remove from microwave and stir until smooth. This is the basic fudge.
Tou may add
1 cup peanut butter
2/3 cup marshmallow creme
1/2 cup chopped nuts---I use english walnuts
I usually always add the marshmallow creme and nuts. Place in a buttered square pan to cool. This is a soft fudge so best to keep it refrigerated or in a cool area.

Sometimes I add a little more milk and use it as a frosting. This is a really good fudge.
