The Good Stuff You’ll Need
- 1 box of brownie mix (choose your favorite brand, or homemade if you’re feeling fancy)
- 1/4 cup vegetable oil (or melted butter if you want a richer flavor)
- 1/4 cup water
- 2 large eggs
- 10 Oreo cookies (broken into halves or quarters, depending on your preference)
- 1/2 cup chocolate chips (optional, but do you really need an excuse for more chocolate?)

Let’s Do This
Step 1: Prep the Pan
Preheat your oven to 350°F (175°C). Grease an 8×8-inch baking dish or line it with parchment paper for easy removal.
Step 2: Mix the Brownie Batter
In a large bowl, combine the brownie mix, vegetable oil, water, and eggs. Stir until smooth — no lumps, just silky goodness. If you’re feeling extra, fold in the chocolate chips for even more chocolatey goodness.
Step 3: Add the Oreos
Take your Oreo cookies and break them into halves or quarters. Gently fold them into the brownie batter — no need to crush them to bits; leave some big chunks for that nice Oreo crunch throughout.
Step 4: Bake the Brownies
Pour the batter into your prepared baking dish and spread it out evenly. Bake for 25–30 minutes, or until a toothpick inserted into the center comes out with just a few crumbs (you want them fudgy, not dry).
Step 5: Cool and Cut
Let the brownies cool in the pan for 10 minutes before transferring to a wire rack to cool completely. Once they’ve cooled down, cut them into squares (or rectangles if you’re really hungry).
Serving Suggestions
- Serve warm with a scoop of vanilla ice cream for an over-the-top dessert experience.
- Drizzle some caramel or chocolate sauce on top for extra indulgence.
- If you’re a fan of whipped cream, pile it high — you know it’s a vibe.
Switch It Up
- Add nuts: Walnuts or pecans would bring a nice crunch to balance the creaminess.
- Go all-in: Top the brownies with a layer of crushed Oreos before baking for that extra Oreo hit.
- Make it minty: Swap in mint Oreos for a fresh twist.
- Add a swirl: Marble in some peanut butter or Nutella for a rich, nutty flavor.
Make-Ahead Tips
- Brownies can be made up to 2 days ahead of time. Just store them in an airtight container to keep them fresh.
- They also freeze well! Store in an airtight container or wrap them individually and freeze for up to a month.

Questions People Actually Ask
Q: Can I make these brownies without eggs?
A: Yes! Use flax eggs (1 tbsp ground flaxseed + 2.5 tbsp water, let sit for 5 minutes) as a great egg substitute.
Q: Can I make them from scratch instead of using a mix?
A: Absolutely! You can swap the mix for a homemade brownie recipe. Just make sure to follow a similar ratio for wet and dry ingredients.
Q: Can I use gluten-free brownie mix?
A: Yes! Just swap in your favorite gluten-free brownie mix, and the rest of the recipe stays the same.
Q: How do I know when they’re done?
A: For fudgy brownies, make sure the toothpick comes out with a few crumbs, not wet batter. Overbaking can make them dry, so check early and often!
