What are magic cookie bars?

Magic cookie bars are a type of cookie bar made with butter, graham crackers, chocolate chips, nuts, shredded coconut, and sweetened condensed milk. Each component is layered into a baking pan before they are baked and then cut into squares. All the layers “magically” come together due to the sweetened condensed milk poured on top before baking.

They are also known as Hello Dolly bars, as a reference to the Broadway musical “Hello, Dolly!” which was popular when these bars were created in the mid 1960s. Over the years butterscotch chips were added to some versions of the recipe and they became known as 7-layer bars as well, for each of the 7 ingredients.

Why this recipe is so great:

  • Easy to make – All you have to do is simply layer everything into a 9×13″ pan, pour the sweetened condensed milk on top, and bake. It’s as easy as that!
  • Tastes amazing – There are so many wonderful flavors and textures in these magic cookie bars which is what I think makes them so great. You’ve got a buttery graham cracker crust, chocolate chips, crunchy nuts, shredded coconut, and ooey gooey sweetened condensed milk binding everything together. Every bite is like a flavor explosion!
  • Keeps well and serves a crowd – These cookie bars keep for up to 5 days so they are a great make-ahead dessert. They also serve up to 24 or more depending on the size you cut them.

Variations & substitutions:

  • Graham crackers crumbs – Oreo cookie crumbs can be used for a more chocolaty cookie bar
  • Chocolate chips – Any kind of chocolate chips work (dark, semi-sweet, milk) and you can swap half with other flavored chips and bits like butterscotch, peanut butter, white chocolate, toffee bits, raisins, etc.
  • Nuts – Any kind that suits your fancy. I’ve also seen recipes that use pretzels instead.
  • Optional – If you’re a cinnamon fan, add a teaspoon of ground cinnamon to the crust mixture. The added spice is great during the holidays and winter months.
