I can only make these a couple of times a year because I can seriously eat the whole pan, that's how delicious and addicting they are! They are sweet, chewy, butterscotchy, peanut buttery, chocolatey squares of heaven. I've heard these called Scotcheroos or O'Henry bars. This particular recipe came from my sister in law Emma (Thanks Em!)
1 c. peanut butter
1 c. sugar
1 c. light corn syrup
1 pkg. milk chocolate chips
1 pkg. butterscotch chips
6 c. rice krispies
Combine sugar and corn syrup in a sauce pan and bring to a boil. Remove from heat and add peanut butter. Stir until smooth. Add rice krispies. Lightly press into a buttered 9X13" pan.
Combine milk chocolate chips and butterscotch chips in a microwave safe bowl. Heat on high for 20 seconds at a time until melted, stir until completely smooth. (You can also do this with a double broiler)
Pour topping over bars and let sit for a couple of hours until topping has set up. Cut into bars and serve. Store covered on counter, do not refrigerate.
