7-Layer Magic Bars
Maybe you know them as Hello Dolly Bars, or 7-Layer Magic Bar, or Magic Cookie Bar, “those easy condensed milk bars,” Millionaire Bars (which is very incorrect, as I eventually learned, because this is a proper Millionaire Bar), or (also like me) “those super yummy bars Grandma used to make for Christmas every year.” Either way, they’re essentially all one in the same! 7-layer magic bars are a clever, easy treat recipe that comes together thanks to a can of sweetened condensed milk.
A graham cracker crust is topped with 4 cups of your chosen toppings (have fun with this or use my recipe for a classic option), then “glued” together with a can of condensed milk, baked, chilled, sliced, and enjoyed by one and all.
7-Layer Cookie Bar Ingredients
- 16 ounces of graham crackers (2 boxes of Kinnikinnick graham crackers), processed into crumbs
- ½ cup of butter (8 tablespoons), melted
- 1 cup of semi-sweet chocolate chips
- 1 cup of white chocolate chips
- 1 cup of pecan pieces
- 1 cup of coconut flakes, unsweetened
- 1, 14-ounce can of sweetened condensed milk
Ingredient Variations and Modifications
These magic cookie bars are a homerun as-is, but if you’re looking for ingredient swaps, we have ideas for you!
- Use different chips – not a fan of the white chocolate + milk chocolate combo? No worries! Use ANY chips you love here. Peanut butter chips, dark chocolate chips, and butterscotch chips would all be really yummy.
- Use a different nut – if you’re out of pecans or just prefer a different nut, feel free to swap in walnuts, peanuts, or even cashews!
- Make them dairy-free – use sweetened condensed coconut milk in place of the regular sweetened condensed milk and dairy-free chocolate chips if you’re looking to make a dairy-free variation.
- Make them gluten-free – everything we make in the Fed & Fit kitchen is gluten-free, so this adjustment is a really easy one! Simply use gluten-free graham crackers (like we did) in place of regular ones to make this sweet treat gluten-free.
- Make them egg-free – the only thing that contains eggs in this recipe is the kind of graham cracker I used for the crust! Any egg-free cookie will be a great substitute.
How to Make Magic Cookie Bars
These cookie bars are incredibly easy to throw together. It’s really just a matter of making a 2-ingredient graham cracker crust (a super easy 5-minute process), layering on toppings galore, and then baking and cooling until set. Here’s the full run-down:
- Prep – preheat the oven to 350°F and line a 9×13 pan with parchment paper.
- Make graham cracker crust – make the graham cracker crust by processing together the graham cracker crumbs and butter, then press into the bottom of the 9×13 pan.
- Add the toppings – sprinkle the toppings (chocolate/white chocolate chips, pecans, and coconut flakes) on top of the crust.
- Pour over the sweetened condensed milk – pour the sweetened condensed milk over top of the toppings.
- Bake – bake the cookie bars for 25-30 minutes until lightly browned.
- Serve and enjoy – let the cookie bars cool, then slice, serve, and enjoy!
Tips for Making
These magic cookie bars could not be ANY easier, but if you’re looking for tips & tricks, we do have a couple!
- Use parchment paper – parchment paper is not a must here, but it does make things a little bit easier. For the least messy results, line your 9×13 baking pan with parchment paper before pressing in your graham cracker crust.
- Make them your own – these cookie bars can be endlessly customized! You’ll really just need 4 cups (total) of mix-ins, so use what you have and have FUN with what you choose. Candy (think: M&Ms) or crushed up cookies would be a really fun addition.
Frequently Asked Questions
You can! Coconut is a pretty common ingredient in these magic cookie bars, but it can absolutely be omitted. As mentioned above, you’ll just need 4 cups total of mix-ins, so you can absolutely swap the coconut for any other topping that you love.
Sure! The answer here is similar to the one above. If you need a nut-free version of these bars, simply swap the 1 cup of nuts for any other mix-in. You’ll just need 4 cups of mix-ins total.
Once the bars are out of the oven, you’ll want to let them cool just a bit, and then stick them in the fridge to set for about 30 minutes. Once they’ve set, you can store them at room temp for up to a week.
You can! Freeze your cookie bars either individually or whole (still in the pan) for up to 3 months. To thaw, either set the pan in the fridge to slowly thaw overnight or thaw an individual magic cookie bar in the fridge overnight or on the counter for an hour or so.
