Double Decker Fudge

I got this from a recipe exchange a long time ago and love it. It is so easy and turns out great every time! Enjoy.

1 Cup Reeses Peanut Butter Chips (I used peanut butter and it turned out great)
1 Cup Semi-sweet Chocolate Chips
2 1/4 cups white sugar
1 (7oz) Jar Marshmallow Creme (I used marshmellows melted down)
3/4 cup evaporated milk
1/4 cup butter
1 tsp vanilla

1. Line 8" pan with foil, extending foil over edges of pan. Measure peanut butter chips into one medium bowl and chocolate chips into second medium bowl.

2. Combine sugar, marshmallow creme, evaporated milk and butter in heavy 3 qt. saucepan. Cook over medium heat, stirring constantly until mixture boils. Boil and stir for 5 minutes. Remove from heat; stir in vanilla.

3. Immediately stir 1/2 hot mixture into peanut butter chips until chips are completely melted. Pour into prepared pan. Stir remaining 1/2 hot mixture into chocolate chips until chips are competely melted. Quickly spread over top of peanut butter layer.

4. Cool completely. Remove from pan; place on cutting board. Peel off and discard foil; cut into 1 inch squares. Store tightly covered.
