GRANDMA'S FABULOUS FUDGE Recipe

In a heavy saucepan, bring butter, sugar and milk to a slow boil, cooking for 5 to 6 minutes. Remove from heat and stir in marshmallow cream, chocolates, and vanilla extract. Using an electric mixer, beat for 5 minutes. (If you want to add nuts, stir them in now.) Pour into a buttered 9 x 13 inch pan. Cool and cut into squares. This fudge keeps well in the refrigerator.
