1 cup peanut butter chips
1 cup semisweet chocolate chips
3/4 cup evaporated milk
1/4 cup butter or margarine
2 1/4 cups granulated sugar
1 (7 ounce) jar Marshmallow Crème
1 teaspoon vanilla extract

Measure peanut butter chips into one mixing bowl and chocolate chips into second bowl; set aside. Butter an 8-inch square pan.

Combine evaporated milk, butter or margarine, sugar and Marshmallow Crème in a heavy 2 3/4-quart saucepan. Cook over medium heat until mixture begins to boil, stirring constantly; continue cooking and stirring 5 minutes.

Remove from heat; stir in vanilla extract. Immediately add about one-half of hot mixture to peanut butter chips, stirring until completely melted; pour into prepared pan. Add remaining hot mixture to chocolate chips, stirring until completely melted. Spread over top of peanut butter layer. Cool.
