Decadent Oreo Brownies

There are some desserts that don’t just satisfy a craving—they transport you back in time. For me, Decadent Oreo Brownies do exactly that. They take me to childhood sleepovers, where we’d sneak cookies late at night, and to the first time I ever helped in the kitchen, stirring brownie batter with too much enthusiasm. These brownies combine two all-time favorites—gooey homemade brownies and classic Oreo cookies—into one bite that feels like a warm hug.

When the weather cools and the oven heats up, there’s a nostalgic comfort in making brownies from scratch. The scent of melting chocolate, the clinking of spoons against ceramic mixing bowls, and the moment you press the Oreo layer into the thick, chocolatey batter—it all becomes part of a baking ritual that feels personal and shared at the same time.

This is the kind of recipe you bring out for snow days, bake sales, birthday parties, or any time you want to feel like a kid again. Whether you’re baking for family or yourself, these Decadent Oreo Brownies promise indulgence and joy in every bite.

• 2 cups (340g) semisweet chocolate chips, divided
• 1/2 cup (100g) granulated sugar
• 2 large eggs
• 1 1/2 teaspoons vanilla extract

HOW TO MAKE DECADENT OREO BROWNIES:

STEP-BY-STEP INSTRUCTIONS:

Step 1: Preheat and Prepare Your Pan
Start by preheating your oven to 350°F (175°C). Line an 8-inch square baking dish with parchment paper, leaving some overhang so you can easily lift the brownies out later. Lightly grease the parchment with cooking spray.

Step 2: Melt Butter and Chocolate
In a large microwave-safe bowl, melt the butter with 1⅓ cups of chocolate chips in 30-second intervals, stirring in between. This usually takes about 1–1.5 minutes total. Let it cool for 5 minutes before proceeding.

Step 3: Stir in Sugar and Eggs
Whisk the granulated sugar into the chocolate mixture until fully incorporated. Add the eggs one at a time, beating well after each addition. Stir in the vanilla extract.

Step 4: Add the Dry Ingredients
Sift in the flour, cocoa powder, and salt. Use a rubber spatula or wooden spoon to gently fold everything together until just combined. Be careful not to overmix, as that can lead to cakier brownies instead of the desired fudgy texture.

Step 5: Fold in More Chocolate
Stir in the remaining 1/3 cup of chocolate chips. This ensures there are melty chocolate pockets throughout the finished brownies.

Step 6: Layer the Batter and Oreos
Spread half of the brownie batter evenly in the bottom of your prepared pan. Lay 16 Oreo cookies on top of the batter in four rows of four. Gently press them down just a bit so they stick.

Step 7: Finish and Top
Spread the rest of the brownie batter over the cookies, smoothing it out to cover everything. Roughly chop the remaining 8 Oreos and sprinkle them on top, along with any leftover chocolate chips.

Step 8: Bake to Perfection
Bake the brownies for 25–30 minutes, or until a toothpick inserted comes out with moist crumbs (not wet batter). Don’t overbake—these brownies are best when soft and fudgy in the center.

Step 9: Cool and Slice
Allow the brownies to cool completely in the pan before lifting them out using the parchment overhang. Slice into squares and enjoy the gooey, chocolatey, cookie-loaded goodness.
