I added mini chocolate chips as I didn't have the right amount of butterscotch chips. It turned out delicious. My kids loved it too. I drizzled smuckers caramel sauce on top.
I made these for a charity bake sale and they all bought in a short time. People came back and bought seconds.
Didn't change a thing except I used Betty Crocker French Vanilla, store did not have Dunkin Hines. Super easy, very sweet.
