My grandmother was the one to introduce me to this tasty desert. She makes it for most family gatherings and it never fails to be a crowd pleaser.
1/2 cup smooth peanut butter
1/4 cup margarine
1 cup butterscotch chips
8 oz (250g) bag multicolored miniature marshmallows
Butter or margarine a 9x9 square baking pan; both bottom and sides so squares don't stick to it.
Put margarine and peanut butter in a large saucepan, stir over medium heat until both are melted together.
Remove from heat and quickly stir in butterscotch chips until mixture is smooth.
Let saucepan cool until lukewarm (so your marshmallows don't melt when adding).
Stir in marshmallows and pour mixture into 9x9 pan.
When solid, cut into desired-sized squares.
Note: make certain no one is allergic to peanuts when bringing to an outing.
