cookies and cream oreo brownies made with brownie mix

Fudgy brownies. Stuffed with Oreos. Topped with cream cheese icing and loaded with sprinkles. These brownies are heaven. Pure heaven. Just look how fudgy they are!

While I have my go-to homemade brownies recipe, I actually used a box mix for today’s brownies. That’s what trying to bake in a rush will do to you. I don’t mind, I love Ghirardelli Dark Chocolate Brownie Mix – they truly taste homemade!

This brownie recipe is fool-proof. Mix up your brownies according to the package instructions. Pour 1/2 of the batter into your baking pan. Line whole Oreos on top of the bottom batter layer. Pour the rest of the batter on top of the Oreos. Bake according to package instructions.

My favorite part about these brownies? The Oreo cookie melts and creates an unbelievably gooey, fudgy brownie encasing the sweet Oreo cream centers. Delicious!

Sprinkle-loaded fudgy brownies stuffed with Oreos and topped with cream cheese icing!




  1. Preheat the oven to 325°F (163°C). Spray 11×7 inch baking pan with nonstick spray. Set aside.
  2. Make brownie batter according to box instructions. Pour 1/2 of the brownie batter into the prepared baking dish. Line Oreos in rows (3 down and 5 across). Pour the rest of the brownie batter over the Oreos.
  3. Bake according to box instructions or until toothpick inserted in the middle comes out almost clean (i like my brownies fudgy!). Mine took about 40 minutes.
  4. Allow to cool completely and frost with cream cheese icing. Top with sprinkles and stick in the refrigerator so the frosting sets. Once the frosting is set (about 1 hour), cut into 24 squares.


  1. Make Ahead Instructions: Brownies stay fresh chilled in the refrigerator for up to 1 week.
  2. Recipe adapted from Averie Cooks.

  1. These are delicious! I crushed some Oreos and blended them into the cream cheese frosting. So yummy!

  2. Omg!! Just made these and they’re A M A Z I N G! Totally gonna have to bake them again! I used store bought brownie mix and frosting, so next time I’ll try your recipes! Thanks!

  3. Making these for easter! They look so delicious and pretty, I can’t wait for everyone to try them!

  4. Hi there!

    Would love to make this. Do you think it would work in a 9×13 pan?

    Thanks! Kate

    1. Kate, there isn’t quite enough batter to make two substantial layers of brownie in a 9×13 pan. How about using two boxes of brownie mix?!

  5. These look amazing. I have a question, though. Say I wanted to do a blondie base, topped with the oreos, then the chocolate brownie batter. Would you recommend using your blondie batter (the one from the candy bar blondies, for example)? Would that make it harder to layer?
    Or do you have another blondie recipe that could possibly work in conjunction with this one? Thanks. 🙂

  6. Hey Sally, how do your brownies in the pictures come out with that nice dark color?

  7. When I first saw this recipe, my mind exploded…..while I wish I had been able to take pictures – they were gone before I could, literally! – I did a few different takes on your recipe. For the choc brownies, I used oreo peanut butter cookies. The different colors were awesome. I also used a blondie and tried both the blonde oreo cookies and the choc oreo cookies – again the color just added a great dimension to it Thank you so much for coming up with this idea. Also, I didn’t use an 11 x 14. I used a 13 x 9 and they came out fine. Probably thicker than yours but followed recipe for ingred’s and time. Awesome!

  8. Hi Sally,

    My boyfriend wants “oreo cake” for his birthday – the oreo cake recipe you posted looks a little over my head, but brownies I can definitely handle. However, I want to get the dark black oreo look like you have here on the brownie itself, without using a box mix.

    I usually use milk chocolate and follow your fudgy brownie recipe, but this results in a lighter brown color brownie. Can I just sub in dark chocolate into that recipe or do I need to adjust the sugar?

    Any help you could provide would be much appreciated. Thank you! Love your blog!

    1. Hi Jenna! Use these brownies. They’re dark and super fudgy. You can use a darker chocolate. No need to increase the sugar. They’re plenty sweet!

  9. Hi Sally,
    I know this recipe is quite old, do you have any updates to it?

      1. I’m definitely looking on those too! but wanted that cream cheese frosting
