Magic Cookie Bars (aka Hello Dolly Bars)

A beloved, classic American dessert bar layered with gooey, crunchy, chocolatey goodness. Simple, versatile, and wildly addictive.

INTRODUCTION

Magic Cookie Bars have been around since at least the 1960s and are sometimes called Hello Dolly Bars, Seven-Layer Bars, or even Dream Bars. The origin? Popularized by Eagle Brand condensed milk ads and the Hello Dolly musical craze of the time, these bars became an instant hit in home kitchens across the U.S.

What makes them “magic”? The way all the ingredients come together without mixing—layered directly in the pan—and then bake into one irresistible, chewy-crispy bar. It’s pure sorcery.

INGREDIENTS

This is the classic version, but variations and lovers of this treat will share fun twists further below!

  • 1/2 cup (1 stick) unsalted butter, melted
  • 1 1/2 cups graham cracker crumbs (about 10-12 full crackers)
  • 1 cup semi-sweet chocolate chips
  • 1 cup butterscotch chips (or white chocolate chips for a twist)
  • 1 cup sweetened shredded coconut
  • 1 cup chopped pecans or walnuts (optional, but amazing)
  • 1 (14-ounce) can sweetened condensed milk

INSTRUCTIONS

  1. Preheat oven to 350°F (175°C).
    If using a glass dish, reduce heat to 325°F.
  2. Prepare your pan.
    Line a 9×13-inch baking dish with parchment paper or grease it lightly.
  3. Create the crust.
    In a bowl, mix the melted butter with the graham cracker crumbs. Press the mixture firmly into the bottom of your pan to form a crust.
  4. Layer the love.
    • Sprinkle chocolate chips evenly over the crust.
    • Add a layer of butterscotch chips.
    • Follow with shredded coconut.
    • Then sprinkle on the chopped nuts.
  5. Pour the magic.
    Drizzle the sweetened condensed milk evenly over the top. Don’t stir—just let it soak and bind everything together during baking.
  6. Bake for 25-30 minutes, or until edges are golden and bubbly.
  7. Cool completely before cutting into bars. This allows them to set and makes slicing clean and easy.

METHOD VARIATIONS & TIPS

  • Nut-free? Skip the nuts and add more coconut or crushed pretzels for a salty crunch.
  • Gluten-free? Use GF graham crackers.
  • Extra gooey? Add another 1/4 cup of condensed milk.
  • Want layers to stand out? Reverse the layering—pour condensed milk before the chips and coconut.

A BRIEF HISTORY

Originally printed by the Eagle Brand Condensed Milk company in the 1960s, the Magic Cookie Bar was part of a wave of quick, convenient, yet decadent dessert trends. The name “Hello Dolly Bars” came shortly after, around the time of the Broadway musical’s popularity.

From PTA meetings to holiday cookie trays, these bars have found their way into generations of hearts and homes. Nostalgia is baked into every bite.
