Make the ultimate chewy Magic Cookie Bars, also known as Seven Layer Bars. This simple recipe uses sweetened condensed milk to create rich, gooey layers of chocolate, coconut, and nuts over a graham cracker crust. It is a crowd-pleaser dessert perfect for parties or holidays.

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, sweetened
  • 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 for easy removal.
  2. Combine the graham cracker crumbs and melted butter in a medium bowl. Press this mixture firmly and evenly into the bottom of the prepared baking pan to form the crust.
  3. Bake the crust for 8 minutes. Remove the pan from the oven.
  4. Pour the entire can of sweetened condensed milk evenly over the warm crust. This milk is key for the gooey texture.
  5. Sprinkle the chocolate chips, butterscotch chips, flaked coconut, and chopped nuts evenly over the condensed milk layer. Do not press the toppings down.
  6. Return the pan to the oven and bake for 20 to 25 minutes, or until the edges are golden brown and the center is set. The top should look bubbly.
  7. Let the bars cool completely in the pan on a wire rack, at least 2 hours, before cutting. Cooling allows the layers to set for clean slices.
  8. Once cool, use the parchment paper overhang to lift the bars out of the pan. Cut into squares.

Notes

  • For a richer flavor, toast the flaked coconut lightly before adding it to the layers.
  • If you omit the nuts, consider adding an extra half cup of chocolate chips to maintain the layer volume.
  • For the chewiest bars, do not overbake; the center should still look slightly soft when you remove them from the oven.
