Crispy Butterscotch Mallow Squares

While looking through my Moms recipe box I came across a small yellow piece of cardboard cut from a cereal box. I put it in my "to try" pile.  Looking for a quick square to make for my day with my daughter, grandson, niece and her children I decided to try this out. It was simple and didn't require too many dishes...and it was a hit! So here is the recipe.....enjoy.

1cup butterscotch chips
1/3 cup peanut butter
4 tbsp. butter
2 cups mini marshmallows
3 cups Rice Krispies
 In saucepan over low heat, combine chips, peanut butter and butter.
Stir constantly until melted and well blended, remove from heat.
Add marshmallows and cereal; stir until well coated. 
Press mixture firmly into a greased 9 inch square pan.
 Refrigerate until firm.
Cut into squares.
