Peanut Butter Rice Krispie Treats

1 cup Karo syrup
1 cup sugar
1 cup peanut butter
5-6 cups Rice Krispies cereal (or store brand works great!)
1 cup chocolate chips (I use about 1 1/2 cups)
(or use half bag of butterscotch chips and half bag of chocolate chips)

On stove top, heat the syrup and sugar until boiling. Remove from heat and stir in peanut butter until well blended. Add Rice Krispies and stir until evenly coated. Press into a greased 9x13 pan. Heat chocolate chips in microwave for one minute. Stir. Heat 30 seconds more if needed. Stir until chips are completely melted. Spread chocolate on top and let cool.
