1 cup butterscotch chips
1 can Pillsbury Chocolate Fudge Frosting Supreme
2 (about 2 ounce) Snickers candy bars, cut up

Line an 8-inch square pan with foil, extending foil over edges; lightly butter foil. Set aside.

In large microwave-safe bowl, combine chocolate chips and butterscotch chips; microwave on MEDIUM for 1 to 2 minutes or until chips are melted. Stir until smooth. Stir in frosting and  all but 2 tablespoons candy bar until mixed. Spread in foil-lined pan; sprinkle with reserved candy bar. Refrigerate 1 hour or until firm.

Remove fudge from pan by lifting foil; remove foil from fudge. Cut into squares.
