3 c. sugar
3/4 c. butter
2/3 c. (5 1/3 oz. can) evaporated milk
6 oz. pkg. semi-sweet chocolate pieces (milk chocolate chips are better)
7 oz. jar Kraft marshmallow creme
1 tsp. vanilla
1/2 c. peanut butter (crunchy or cream style)

Combine 1 1/2 cups sugar, 6 tablespoons butter and 1/3 cup milk in heavy 1 1/2 quart saucepan; bring to full rolling boil, stirring constantly. Continue boiling 4 minutes over medium heat, stirring constantly to prevent scorching. Remove from heat; stir in chocolate pieces until melted. Add 1 cup (1/2 jar) marshmallow creme and 1/2 teaspoon vanilla; beat until well blended.

Pour into greased 13"x9" pan. Repeat with remaining ingredients, substituting peanut butter for chocolate pieces. Spread over chocolate layer. Cool at room temperature; cut in squares.
