7 layer Oreo bars

There’s a lot to love about magic bars. They’re generally easy to make, the variations are endless and everyone loves them! I love experimenting with new recipes and these magic Oreo bars are a new obsession. Some people call them black magic bars, but whatever you call them everyone agrees – they are amazing.

They’re basically Oreo cookie bars with condensed milk and a few other sweet ingredients. If you love cookies and cream you will love these treats!

Magic bars with Oreos

What are Magic Bars?

A classic magic cookie bar, also known as dolly bars, usually has multiple layers and are made with condensed milk. I have countless recipes on my site because once you know how to make a basic recipe you can easily customize it and switch it up so many ways.

These magic bars with Oreos have four layers:

  • Cookies and cream crust
  • White chocolate chips
  • Chopped Hershey’s cookies and cream bars
  • Sweetened condensed milk
Oreo crust

The easiest way to make the crust is with a food processor. Just pulse the cookies until they bread down into crumbs then mix them with melted butter.

If you don’t have a food processor, you can place the cookies in a resealable bag and crush them with a rolling pin or meat mallet. It’s a good stress reliever!

Once you’ve mixed in the butter all you have to do is press the mixture into the bottom of your baking pan.

Assemble the Rest of the Layers

  • Spread the white chocolate chips and chopped Hershey’s bars over the crust.
  • Coarsely chop some more Oreo cookies. I like to keep them in bigger chunks – you don’t need to finely chop them. Sprinkle them over the top of the white chocolate and candy bars.
  • Pour the sweetened condensed milk evenly over the top.
  • Bake for 20 to 30 minutes and cool them completely before serving.

I told you it was easy! After they’ve baked and cooled, they have all of those sweet layers on top of the cookie crust. They are the ultimate cookies and cream bar.


Not a fan of white chocolate? You can substitute milk chocolate chips and regular Hershey bars if you want them extra chocolatey! 

Or, you can do a combination of regular chocolate and white chocolate, so feel free to experiment.

How to Store Cookies ‘n Cream Bars

Once they are cooled, they will keep in an airtight container for several days. 

You can also freeze them! Slice them and then place them in a single layer on a baking sheet. Pop it in the freezer for 30 minutes and then, once they’re frozen, you can keep them in a freezer container or bag for several months.

Freezing them in a single layer first will prevent any sticking – if you just pile them in the container they will stick and freeze together.

Make these Oreo Dessert Bars when you’re Feeding a Crowd!

They are rich and sweet so a little goes a long way! I love making these for events like potlucks, parties, and BBQs because they stretch to serve a crowd. 

I hope you love this recipe – enjoy!

  1. Dorothy, what size are the 4 Hershey’s Cookies ‘n Cream bars? I found two different sizes at the grocery store (one is 1.55 oz and the other 4 oz)…. 🙂 Thank you!

  2. I’m anti white chocolate. 🙁 sorry
    What can I replace them with? You have several recipes with white chocolate. The pumpkin bars and these oreo bars I really want to make but uncertain what to use instead. Help please!

    1. Anytime I use white chocolate, feel free to sub what you like! For these magic bars, either milk or semi-sweet. The pumpkin ones would be great with either chocolate too – or even some cinnamon chips. Think about the flavors you like, the combos you like, and give them a try. Then let me know what works! 🙂

  3. I have a funny question, I see all of the really yummy food/treat stuff you have going on (that I keep pinning). Are you eating it all or giving it away, because if it was me I would eat it all and gain 30 in a week!!!! But it just looks SO good!

    1. I do eat a lot of it! But I try to freeze it and give it away as much as I can. I work out at least an hour 6 days a week to make up for it!

      1. Would these bars freeze? Great idea! This sounds amazing and I’m trying to find something I can make ahead of time to have on hand for visitors next week.

      2. Yes, totally! Just be careful if you stack them in with anything in between, they might stick to wax paper or paper towels (the SCM can be sticky), so it’s best to freeze them in a single layer.

  4. so I tried to make someone else of this today… and it was a major fail, I think I am going to try yours tomorrow, its less better but made with halloween oreos! if you want to see my MAJOR fail check it out on my blog, really its kinda funny
