Secret Ingredient Rice Krispies Squares

I have never made this recipe but it sounds good. I don't know how long the prep time is. If you make it let me know how it turns out. The secret ingredient is butterscotch chips. These melt in with the marshmallows and help create a more substantial square. Enjoy.
