Why You’ll Love This Recipe

Hello Dolly Bars—also known as Magic Cookie Bars, Seven Layer Bars, or Coconut Dream Bars—are one of those vintage desserts that never goes out of style. They’re rich, chewy, and packed with layers of chocolate, butterscotch, coconut, and nuts, all held together with sweetened condensed milk. The buttery graham cracker crust on the bottom and that sticky, sweet topping that sets up into neat slices make them absolutely irresistible .

The name “Hello Dolly” is a tribute to the musical “Hello Dolly!” which was popular on Broadway in the mid-1960s, around the same time these bars became famous . Whether you call them magic bars or seven-layer bars, one thing’s for sure—they disappear fast!

Ingredients

For the Crust:

1½ cups graham cracker crumbs
½ cup (1 stick) unsalted butter, melted
2 tablespoons granulated sugar (optional, for extra sweetness)

For the Layers:

1 (14-ounce) can sweetened condensed milk
1 cup semisweet chocolate chips
1 cup butterscotch chips
1 cup sweetened shredded coconut
1 cup chopped pecans or walnuts

Directions

1. Preheat and prepare. Preheat your oven to 350°F (175°C). Line a 9×13-inch baking pan with parchment paper, leaving some overhang on two sides to create “handles” for easy removal . Lightly grease the parchment.

2. Make the crust. In a medium bowl, combine the graham cracker crumbs, melted butter, and sugar (if using). Stir until the crumbs are evenly moistened. Press the mixture firmly and evenly into the bottom of the prepared pan. Pressing it down well is key—it helps the crust hold together when you slice the bars .

3. Layer the fillings. Sprinkle the semisweet chocolate chips evenly over the crust, then sprinkle the butterscotch chips over that. Follow with the shredded coconut and chopped nuts .

4. Add the condensed milk. Slowly drizzle the sweetened condensed milk evenly over the entire top. Gently spread it a bit with a spatula so it covers as much of the surface as possible .

5. Bake. Bake for 25 to 30 minutes, until the edges are golden brown and bubbling and the coconut is lightly toasted . The center should look set but still a little soft—it firms up as it cools .

6. Cool and slice. Let the bars cool completely in the pan on a wire rack. This can take 2-4 hours . For cleaner cuts, refrigerate for 30-60 minutes before slicing . Use the parchment handles to lift the entire slab out of the pan, then cut into squares with a sharp knife, wiping the blade clean between cuts .

Variations

Swap the chips: Use white chocolate, peanut butter, or toffee chips instead of butterscotch
Different nuts: Try almonds, macadamia nuts, or hazelnuts
Nut-free: Simply omit the nuts or add extra coconut and chocolate chips
Gluten-free: Use gluten-free graham crackers or crushed gluten-free cookies for the crust
Chocolate twist: Mix cocoa powder into the sweetened condensed milk for a chocolate “glue”
Add marshmallows: For an extra layer of gooeyness, add mini marshmallows before baking

Expert Tips

Press the crust firmly. A well-packed crust prevents crumbling when slicing .
Use parchment paper. These bars can be sticky, and parchment makes lifting and cutting much easier .
Don’t rush the cooling. Cutting too soon will result in gooey, messy bars. Let them cool completely and chill for the cleanest slices .
Sweetened condensed milk is essential. Don’t substitute evaporated milk—it won’t set the same way .

Storage

Room Temperature: Store in an airtight container for up to 1 week .

Refrigerator: Store for up to 2 weeks. They’re delicious cold and slice neatly .

Freezer: Freeze for up to 3 months. Thaw at room temperature before serving .
