Easy Oreo Brownies

Many years ago, we purchased a box mix at the Supermarket to make Oreo Brownies. They were a HUGE hit in our family. Unfortunately, the next time I searched for them at the store, we discovered they no longer sold them. I guess we were late to the party discovering them, and perhaps others were as well, so the brand discontinued them. 

My kids still remember those Fudgy Oreo Brownies and they ask for them from time to time. I’ve been experimenting with various recipes to try and replicate the deliciousness that we remember so fondly. I’ve finally found a recipe that we think hits the mark.

This is a really Easy Oreo Brownie recipe, made using your favorite box of brownie mix, my Homemade Brownies Recipe, or any brownie recipe of your choice as the base mix. Then simply add crushed Oreo sandwich cookies to increase the Oreo flavor.

How to make Oreo Brownies:

  • Pre-heat oven to desired temperature for brownie recipe you’ll be using.
  • Prepare your boxed Brownie Batter, or Homemade Brownie Batter according to the instructions or recipe.
  • Chop or crush the Oreo cookies.
  • Mix most of the crushed cookies into the brownie batter, reserving just enough to sprinkle on top of the baked brownies.
  • Bake according to brownie recipe instructions.
  • In a small mixing bowl, combine the powdered sugar and milk.
  • Stir until the combination is smooth with no lumps, and thin enough to drizzle over brownies.
  • Drizzle over brownies using a spoon until all are covered.

Variations to the Oreo Brownie recipe:

There are a variety of ways you can make Oreo brownies, for example:

  • Adjust the amount of Oreo cookies and icing that you use, to suit your personal preferences.
  • Many people like to include whole Oreo’s in the bottom of the pan, then cover with the brownie mix.
  • For the purposes of this recipe, in our home we prefer to crush the Oreo’s, and stir the crushed cookies in with the brownie batter.
  • You can use big chunks, small tiny crumbs, whatever you enjoy!

Oreo Brownies Recipe Ingredients:

  • BROWNIE MIX – Use the Brownie Mix of your choice. If you want to make your own brownie batter, try my Homemade Brownie Batter recipe.
  • ADDITIONAL INGREDIENTS – These will depend on the mix or brownie recipe you’re following:
    • COOKIES – You may need 10 crushed Oreo cookies.
    • SUGAR – 1/2 cup of powdered sugar may also be needed.
    • MILK – Finally 2 1/2 tablespoons of milk, I’ve used whole but any type of milk will work.

Flavor variations & substitutions for making Oreo Brownies:

  • Use any flavor of Oreo Cookies to change up the flavor!
  • Try adding chocolate chips, peanut butter chips, or any flavored candy chips/chunks of your choice.
  • Serve while warm with vanilla ice cream and a drizzle of caramel or chocolate syrup.
  • Make them into S’mores Oreo Brownies by tossing in some Graham Cracker crumbs & small marshmallows.
  • Try substituting Mini Reese’s Peanut Butter Cups for the Oreo cookies.

Recipe hints & tips:

  • Don’t over mix your brownie batter! Be sure to stir by hand and stop when ingredients are just combined.
  • My boys love brownies, but to help control portion size I’ve started using one of the pre-portioned brownie pans. This allows everybody to get an edge piece and makes them acknowledge what a proper portion size is. They still have to exercise SOME control in not eating multiple pieces, but does help!

FAQs

How to store leftover Oreo Brownies?

If your brownie pan has a lid that fits tightly, you can just use that and store at room temperature for up to 4 days. If your pan doesn’t have a lid, cut into portion sizes and store in a rubbermaid container at room temperature for up to 4 days.

If my kids are taking to school with lunch, I’ll put a cut slice in a ziplock bag and it can be stored at room temperature or in the refrigerator (with the rest of their lunch so they don’t forget it) and packed into their lunch bag.

How to freeze Oreo Brownies?

Once baked and cooled, just wrap the bars individually with Saran Wrap, place them in a Ziploc bag and store in the freezer for up to 2 months. Thaw the brownies at room temperature when you’re ready to eat them, then serve and enjoy!
