Recipe Variations
Double Chocolate Hello Dolly Bars. Don't care for butterscotch? Use two types of chocolate in these cookie bars and leave out the butterscotch! I love to make one layer of dark chocolate chips and another layer of semi-sweet chocolate chips, then proceed with the remaining ingredients according to the recipe. So perfect for the chocolate lover!
Toffee Hello Dolly Bars. Replace the butterscotch with an equal amount of toffee chips.
Butterfinger Hello Dolly Bars. Use an equal amount of butterfinger chips for the butterscotch.
Chocolate Chip Oat Hello Dolly Bars. Want something other than coconut? Replace the coconut with rolled oats.
Peanut Butter Chocolate Hello Dolly Bars. Love peanut butter? Replace the butterscotch with peanut butter chips and chopped cocktail peanuts for the nuts.
Nut-free Hello Dolly Bars. While I love to use pecans, walnuts, and even peanuts, you can also omit the nuts and add more chips if you like or need a nut-free cookie bar!
