When my boys were in Scouts, their leader, Dr. David Mason, often made these treats for them. They are simple and delicious.
1 c. sugar
1 c. white corn syrup
Mix and melt in microwave until it bubbles (approximately 90 seconds).
Add 1 c. peanut butter and stir until well mixed.
Add 6 c. rice krispies, mix well and press into a buttered 9 x 13" pan.
Melt 6 ounces chocolate chips and 6 ounces butterscotch chips together in microwave for about 90 seconds, stirring after each 30 seconds. Spread over top of rice krispie mixture and refrigerate until time to serve.
