Bake 25-30 minutes, or until edges are lightly golden. Let cool completely in pan on a wire rack.
Use the foil overhang to remove it from the pan. Cut Hello Dolly Bars to desired size. Eat & Enjoy!
Notes
Hello Dolly Bars should be stored in an airtight container and will keep 4+ days.¹ Chopped nuts are optional.² I used chopped walnuts, but chopped pecans would also be fabulous.
