Easy Oreo Brownies Recipe

If you’re a regular reader, you know I’m a fan of cake mix hacks, and while brownies aren’t technically a cake, I also have a lot of brownie upgrades here on All Things Mamma too, like Peanut Butter Cup Brownies. I love them all, but if you’re looking for the easiest way to upgrade a box of brownie mix, I think Oreo Brownies are the winner.

The Oreos add a nice texture to fudgy, chewy brownies-from-a-box, with some getting soft in the middle, and others on top remaining crisp. And then all that tasty Oreo filling adds a hint of vanilla flavor to the chocolate, which is so good!

I also have to mention that these brownies are the best for making brownie sundaes. Warm them up just a little bit, then top them with a scoop of vanilla or cookies-n-creme ice cream and your favorite sundae toppings. Yum!

How to Make Oreo Brownies

1. Prepare

Preheat the oven to 350ºF and grease the bottom of an 8×8 baking dish with cooking spray or butter.

2. Make the Brownie Batter

In a large mixing bowl, whisk together the brownie mix, oil, water, and eggs until well combined.

3. Assemble

Pour half of the brownie batter into the baking dish, then sprinkle half of the chopped Oreo cookies on top. Add the rest of the brownie batter, followed by the remaining Oreos.

4. Bake

Bake the brownies for 25 minutes, or until a cake tester comes out clean. Cool completely before cutting and serving.

FAQ

How do you make easy brownies?

While homemade brownies are easy, using a boxed mix is definitely easier because measuring all the dry ingredients is done for you. This recipe for Oreo brownies is super easy because it starts with a boxed mix!

Are brownies supposed to be gooey?

Some brownie recipes are gooey, but this one is not. The center should be fudgy, but if it’s gooey, it needs more time in the oven.

Are brownies better with butter or oil?

It depends on what you’re looking for in a brownie! Butter tends to be better for cake-like brownies, while oil is better for dense, fudgy brownies.
