There are many recipes out there for scotcharoos and I've tried quite a few - how heavenly chocolate, peanut butter, and butterscotch are together - but this is by far the best recipe I have come across. The rice krispie part is a lot softer/moister (yay) than others and I think the brown sugar gives them a more butterscotchy/carmely/peanut butter taste.
My Favorite Scotcharoo Bars
1 cup brown sugar
1 cup corn syrup
1 teaspoon vanilla
1 1/2 cup peanut butter
6 cups rice krispies
1 cup semi sweet chocolate chips
1 cup butterscotch chips
In a large saucepan or a pot bring the brown sugar, corn syrup, and vanilla to a boil. Remove from heat and stir in peanut butter till smooth. Stir in rice krispies. Press into a greased 9x13 pan, spray your hands with non-stick spray and press the mixture evenly into the pan.
In a microwave safe bowl combine the chocolate and butterscotch chips. Microwave in 30 seconds intervals, stirring after each time, till chips are melted and smooth. Spread this over the rice krispies mixture evenly. Refrigerate for 20 minutes before cutting. Cut into bars. Should make about 20 servings.
