These Oreo brownies are one of my favorite ways to upgrade boxed brownie mix!
Boxed fudge brownie mix Vegetable oil Water Eggs Oreo cookies
Preheat the oven to 350ºF and grease the bottom of an 8×8 baking dish with cooking spray or butter.
In a large mixing bowl, whisk together the brownie mix, oil, water, and eggs until well combined.
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.
Bake the brownies for 25 minutes, or until a cake tester comes out clean. Cool completely before cutting and serving.
You’ll love the combination of crunchy Oreos and rich, fudgy brownies.
