MICROWAVE METHOD: In 1 quart microwave dish combine chips with sweetened milk. Cook on 100% power (high) 3 minutes; stir until chips melt and mixture is smooth. Stir in remaining ingredients. Spread evenly into wax paper lined 9 inch square pan. Chill about 2 hours or until firm. Turn fudge onto cutting board; peel off paper and cut into squares.
If want, substitute 12 ounce package Nestle's Semi-Sweet chocolate chips for the Reeses Peanut Butter Chips to make chocolate fudge. Make according to directions above with the rest of the ingredients.
