Size-Wise: A serving of this sweet treat is 2 squares. You'll find that a small portion goes a long way on chocolate flavor.

Classic Fantasy Fudge: Prepare recipe as directed, using 3/4 cup butter and substituting 1 package (12 oz.) semi-sweet chocolate chips for the chopped BAKER'S Semi-Sweet Baking Chocolate and a 13x9-inch pan for the 9-inch square pan.
