Make these simple, crowd-pleasing Magic Cookie Bars, also called 7-Layer Bars or Hello Dollies, using sweetened condensed milk for a perfectly gooey texture.

Ingredients

Scale
  • 1 1/2 cups graham cracker crumbs
  • 1/2 cup unsalted butter, melted
  • 1 (14 ounce) can sweetened condensed milk
  • 1 cup semi-sweet chocolate chips
  • 1 cup butterscotch chips
  • 1 1/2 cups flaked coconut
  • 1 cup chopped pecans or walnuts

Instructions

  1. Preheat your oven to 350 degrees Fahrenheit. Line a 9×13 inch baking pan with parchment paper, leaving an overhang on the sides for easy removal.
  2. In a medium bowl, mix the graham cracker crumbs and melted butter until the crumbs are evenly moistened.
  3. Press the crumb mixture firmly and evenly into the bottom of the prepared baking pan to form the crust.
  4. Pour half of the can of sweetened condensed milk evenly over the crust.
  5. Sprinkle half of the chocolate chips, half of the butterscotch chips, half of the coconut, and half of the nuts over the milk layer.
  6. Drizzle the remaining sweetened condensed milk over the first layer of toppings.
  7. Top with the remaining chocolate chips, butterscotch chips, coconut, and nuts in even layers.
  8. Bake for 25 to 30 minutes, or until the edges are golden brown and the center is set.
  9. Remove the pan from the oven and let the bars cool completely in the pan on a wire rack. Cooling is important for clean slicing.
  10. Once cool, use the parchment paper overhang to lift the bars out of the pan. Cut into squares before serving.

Notes

  • For a richer flavor, toast the coconut lightly before adding it to the layers.
  • If you do not have butterscotch chips, you can substitute them with an equal amount of white chocolate chips.
  • Chill the bars for at least two hours before slicing for the neatest cuts.
