See the recipe box below for exact amounts and step-by-step instructions.
- Boxed fudge brownie mix – Choose your favorite brand.
- Vegetable oil, water, eggs – The standard liquid ingredients called for on the box.

How to Make Brownie Mix With Oreos
- Combine the mix and liquids: In a large bowl, add the boxed brownie mix, the oil, water, and eggs called for on the box.
- Mix until smooth: Whisk or stir until the batter is uniform. Avoid overmixing.
- Layer with Oreos: Pour half the batter into the prepared pan, sprinkle half the chopped Oreos over the batter, then add the remaining batter and top with the rest of the Oreos.
- Bake and cool: Bake at 350°F (175°C) for about 25 minutes or until a toothpick inserted near the center comes out mostly clean with a few moist crumbs. Cool completely before slicing for the best texture and clean edges.
How to Store
- Room temperature: Place brownies in an airtight container for up to 3–4 days. Keep them away from direct sunlight or heat to preserve fudginess.
- Freeze: Wrap tightly in plastic wrap and place in a freezer-safe bag or container for up to 3 months. Thaw at room temperature before serving.
Frequently Asked Questions
Using a boxed brownie mix keeps this recipe quick and foolproof. Mix the batter according to the package, fold in chopped Oreos, layer in the pan, and bake. The boxed mix removes the need to measure dry ingredients and speeds up prep.
These brownies are intended to be fudgy in the center rather than runny. If they seem too gooey after baking, give them a few extra minutes in the oven and allow them to cool fully—cooling firms up the texture.
Oil keeps boxed brownies dense and fudgy, while butter can produce a slightly richer, more cake-like crumb. Follow the package directions for the texture you prefer.

Oreo Brownies
Ingredients
- 1 box fudge brownie mix
- ⅔ cup vegetable oil
- ¼ cup water
- 2 large eggs
- 1 ½ cups Oreo cookies, roughly chopped
Instructions
- Preheat the oven to 350°F (175°C). Grease the bottom of an 8×8-inch baking dish or line it with parchment paper for easy removal.
- In a large bowl, whisk together the boxed brownie mix, ⅔ cup vegetable oil, ¼ cup water, and 2 large eggs until the batter is smooth and uniform.
- Pour half the batter into the prepared pan and spread evenly. Sprinkle half of the chopped Oreo cookies over the batter.
- Top with the remaining batter and sprinkle the remaining Oreos over the top.
- Bake for about 25 minutes, or until a toothpick inserted near the center comes out with a few moist crumbs. Avoid overbaking to keep the brownies fudgy.
- Cool completely in the pan before slicing to achieve clean edges. Serve plain or with a scoop of ice cream for a brownie sundae.
Notes
- Use a metal baking pan for more even heat distribution and browning.
- Allow brownies to cool fully before cutting to prevent crumbling and to set the fudgy center.
- If you prefer extra fudgy brownies, remove from oven a minute or two earlier; for firmer brownies, bake a little longer.
- Line the pan with parchment paper with an overhang for easy lifting of the whole slab.
- Add a pinch of instant espresso powder to the batter to deepen the chocolate flavor without tasting like coffee.
