O'Henry Bars

I made these bars a few weeks ago. The recipe is from my Sister-in-law Laura's family cookbook. These are seriously good.

O'Henry Bars
1/2 cup butter (1 stick)
1 cup light corn syrup
1 cup sugar
1 cup peanut butter
8-10 cups rice krispies
6 oz. chocolate chips
6 oz. butterscotch chips

Melt butter. Add corn syrup and sugar. Bring just to a boil and remove from heat. Stir in peanut butter. Add rice krispies and mix well. Press mixture into large baking sheet (11X17). Melt the chocolate and butterscotch chips in the microwave on high for 2 minutes. Stir. Continue microwaving for 30 second spurts until chips are melted. Spread chips on top of rice krispie mixture. Let chocolate set.
