Magic cookie bars recipe, sometimes called Hello Dolly bars, are an irresistible bar cookie featuring decadent layers: a buttery graham cracker crust, chocolate chips, butterscotch chips, nuts (I like pecans) and shredded coconut bound together with a can of Eagle Brand sweetened condensed milk.
You'll realize the magic in these 7-layer bars when you eat your first bite.
These bar cookies are ridiculously easy to make but they taste like you spent hours in the kitchen.
These magic bars with condensed milk are a popular treat during the Christmas holidays.
If you're after holiday treats, you must also make Cinnamon Christmas Cookies and to go with them Red Hot Apple Cider + Holiday Drinks.
How Hello Dolly Bars Got Their Name
Bar cookies are great because they're time savers. You're not portioning cookie dough by hand with a cookie scoop. You're just slicing the bars once they've finished baking.

Instructions
Use this section for process shots, alternating between the step and image showing the step. Users don't like seeing process shots cluttering up the recipe card, so include your process shots here.
Use your senses to know when the bar cookies are done. They will smell done and the coconut will look lightly toasted when the bars are done.
Substitutions
- Graham cracker crumbs - use whatever you have--regular or cinnamon or chocolate even
- Nuts - I like to use pecans but use whatever you have. Be sure to chop the nuts into small pieces.
- Chips -use whatever type of chips you have. I usually use semi-sweet morsels but you can use whatever you have, milk chocolate or dark or a flavored chip like cinnamon or espresso.
Magic bars are endlessly customizable.
Variations
You can do all kinds of variations on magic bars.
- Peanut - use peanut butter chips instead of chocolate chips and use chopped peanuts for the nuts.
- Add pretzels in with the graham crackers for the crust - add chopped toffee bits instead of butterscotch chips.
- Peppermint - make a festive version with peppermint chips instead of butterscotch
Equipment
- You'll need a 13x9 pan, I really like this Nordicware pan, which comes with a lid.
- Parchment paper
- A sharp knife or a bench scraper for slicing the bars.
- And then of course, an oven to bake them in.
Storage
Store magic bars in a container with a tight fitting lid for up to a week.
Freeze well wrapped in a freezer-safe container for up to 3 months.
Freezing directions: slice bars and freeze each bar on a tray separately, kind of like you're freezing berries. Then once frozen, wrap in freezer safe paper or foil and put in a freezer safe container.
Top tip
Don't overbake the bars.
When you're layering the ingredients, press down lightly on each layer with your hands before adding the next layer. This will help the bars stay together.
Store magic bars at room temperature in an airtight container. This Nordicware 13x9 pan is great. The pan comes with a lid so you can store the bars in the same pan you used to bake them. 
Yes, but before freezing them, slice the bars and freeze them in individual bars or triangles. Once they're frozen, wrap them well in freezer paper or foil and tuck them in a freezer-safe container. You can freeze the 7-layer bars for up to three months.
You can store magic bars for up to a week at room temperature. Or freeze, tightly wrapped, for up to three months.
