1/2 cup butter or 1/2 cup margarine
1 cup peanut butter
1 (300 g) bags butterscotch chips
1 (200 g) bags mini-white marshmallows
Melt together butter, peanut butter, and butterscotch chips on very low heat until mixed, stirring constantly. Cool for a bit (so as not to melt the marshmallows).
Stir in mini marshmallows.
Pour in a greased 11″ x 13″ pan.
Refrigerate and cut into small (1-1/2″) squares.
