Fudgy Oreo Brownies

If you know me, you know I love to doctor up a box of brownie mix and make fun brownie variations or even brownie mix cookies. This Oreo brownie version is a favorite, as well as chocolate mint brownies, peanut butter brownies and cheesecake brownies.

These delicious Oreo brownies are so good and since they use a box mix like my chocolate fudge caramel brownies, they are so EASY to make. These brownies with Oreos are rich and chewy with a moist crumbs! Any dessert with chocolate and Oreos is a winner in my book.

Recipe Ingredients

For this Oreo brownie recipe, I used Ghiradelli brownie mix – my absolute favorite! I went big time with DOUBLE chocolate! Mmm…so good! You could of course use your favorite homemade brownies, too. Easy and delicious!

Baking Tips

  • Feel free to use a homemade brownie recipe if preferred.
  • Use a plastic knife to easily cut the Oreo brownies once cooled.

Recipe FAQs

What makes brownies fudgy vs cakey?

The fudgier the brownie, the more fat to flour ratio it will have. Meanwhile, cakey brownies will use more flour than fat. For instance, adding an extra egg can make brownies fudgier but adding too many will lead to a rubbery texture.

Can this Oreo brownie recipe be cut in half?

Absolutely! Simply use 1 box brownie mix and half box Oreo’s and make in a small 8×8-inch baking dish.

Storing

The Oreo brownies will keep in an airtight container at room temperature up to 5 days.
