Butterscotch Apple Toffee Bars, an easy fall dessert recipe with graham crackers, toffee, butterscotch, apple chips, and walnuts. These toffee bars aren’t exactly cookies and aren’t exactly candy. They’re kind of in between and the best of both worlds. You start with a layer of graham crackers. Then pour a simple sugar and butter toffee mixture on top. Add some crushed apple chips. Then melt butterscotch chips on top and add chopped walnuts.
