I think this might be a Rice Krispey recipe, not sure. All I know is I've loved these ever since I was little.
1 Cup Sugar
1 Cup Light Corn Syrup
1 Cup Creamy Peanut Butter
6 Cups Rice Krispies
1 Cup Semi-Sweet Chocolate Chips
1 Cup Butterscotch Chocolate Chips
Combine sugar and corn syrup in a large sauce pan over medium heat. Once it starts to bubble, remove from heat and add peanut butter. Once it's well mixed, fold in Rice Krispies. Pour mixture into a 9 x 13 cake pan.
Melt butterscotch chips and semi-sweet chocolate chips in a microwave safe bowl for 30 seconds. Remove and stir. Repeat one to two more times. Once completely melted, pour over Rice Krispey mixture and spread evenly. Cut soon after or else they harden and it's really hard to cut after that.
Oh and as a little side note, make sure you lick the spoons. It's delicious and you don't have to worry about salmonella poisoning like with cookie dough so lick away!
