These Oreo brownie cookies mix the gooey richness of brownies with crunchy, creamy Oreos for a delicious treat. Great whenever you want a cozy chocolate dessert with a fun twist.
I first baked these for a laid-back weekend hangout and they vanished fast. They quickly became a favorite in my collection because they're simple and everyone loves them.
What You'll Need
- Unsalted butter, 1 cup: gives richness and moisture
- Four large eggs: hold it all together and add a bit of creaminess. Fresh ones taste best
- One cup cocoa powder: packs in the bold chocolate flavor. Use a good-quality unsweetened type
- Two cups sugar: sweetens and keeps the batter tender
- One teaspoon vanilla extract: adds a nice aroma
- One cup all-purpose flour: gives the structure. Sift it first for smooth batter
- Half teaspoon baking powder: lifts the cookies gently for a soft crumb
- Half teaspoon salt: brings out the sweetness and balances flavors
- One cup chopped Oreo cookies: tossed in for extra texture and flavor. Freshly chopped pieces work best
Step-by-step Instructions
- Get Oven Ready:
- Heat your oven to 350°F (175°C). Grease your baking pan well so nothing sticks and your cookies come out smooth.
- Butter and Sugar First:
- Melt the butter until just liquid and mix in the sugar right after. This makes a rich and creamy base by softening the sugar.
- Add Vanilla and Eggs:
- Beat in the eggs one by one with the vanilla, mixing well after each. This keeps the batter smooth and adds a light but thick texture.
- Mix in Dry Stuff:
- Sift together cocoa, flour, salt, and baking powder, then gently fold into the wet mix. Don’t overmix or you’ll risk tough cookies.
- Fold in Oreos:
- Carefully fold in the Oreo bits so they’re spread through the batter but not crushed too much. These chunks add crunch and creamy surprises.
- Bake and Chill:
- Pour the batter evenly in the pan. Bake for 25 to 30 minutes, checking around 25 minutes so you get a soft, fudgy center. Let them cool fully before slicing for neat squares.
I like to sprinkle a pinch of sea salt on top before putting them in the oven. It makes the chocolate and Oreo flavors pop. These treats always remind me of chill afternoons baking with family and sharing warm goodies.
Best Ways to Keep Them Fresh
Keep the cookies in an airtight container at room temp to stay soft and tasty for up to three days. If you want to save them longer, freeze the squares separated with parchment paper. Thaw at room temperature before eating. Avoid the fridge unless you like firmer chocolate texture.
Ways to Mix It Up
Swap Oreos for peanut butter or mint sandwich cookies to switch things up. Toss in nuts like pecans or walnuts to add crunch and a nutty twist. Throw in mini chocolate chips or white chocolate chunks for extra chocolatey richness.
Things to Serve With
These Oreo brownies bring together classic flavors and rich chocolate in a way that always feels like a little celebration. Baking them brightens any day and makes it a bit sweeter.
