Hello Dolly bars begin with a graham cracker crust made with melted butter, topped with a combination of flaked coconut, chocolate chips, pecans, and condensed milk and baked at 350 degrees Fahrenheit for 20-30 minutes. Some recipes also add butterscotch chips.
To make Hello Dolly bars, begin by preheating the oven to 350 degrees Fahrenheit. Combine two cups graham cracker crumbs, 1/3 cup melted butter, and 3 tablespoons of sugar in a medium bowl. Press this mixture into the bottom of a lightly greased 13 x 9-inch pan and bake for 8 minutes.
Once the crust is hot, sprinkle one cup of pecans, one cup of semisweet chocolate chips, and 2/3 cup of shredded coconut over hot crust. Pour a 14-ounce can of sweetened condensed milk over top, but do not stir everything together. Bake the Hello Dolly bars for 20 to 25 minutes at 350 degrees. Once the bars are baked, allow them to cool on a wire rack or in the refrigerator for at least an hour before cutting into squares.
This recipe can easily be adapted to suit individual tastes. Some variations call for an equal amount chocolate and butterscotch chips, while others call for different proportions of ingredients.
