Key Ingredients for Easy Oreo Brownies
- 1 cup (2 sticks) unsalted butter, melted
- 2 cups granulated sugar
- 4 large eggs

How to Make Easy Oreo Brownies
These Easy Oreo Brownies are a dream to make, requiring just one bowl and minimal fuss for maximum flavor. Get ready for a rich, dense texture punctuated by delightful cookie crumbles and a slightly gooey center that will have you coming back for more. Preparation time is approximately 15 minutes of active time and 25-30 minutes of baking.
Step-by-Step Instructions
- Preheat and Prep: Preheat your oven to 350°F (175°C). Grease and flour a 9×13 inch baking pan, or line it with parchment paper, leaving an overhang on the sides to easily lift the brownies out later. This ensures your brownies won’t stick.
- Wet Ingredients: In a large mixing bowl, combine the melted butter and granulated sugar. Whisk until well combined and smooth.
- Add Eggs and Vanilla: Add the four large eggs to the butter-sugar mixture, one at a time, whisking well after each addition. Stir in the vanilla extract until everything is fully incorporated.
- Dry Ingredients: In a separate, smaller bowl ( or directly on top of the wet ingredients if you’re feeling bold and want to minimize dishes!), whisk together the all-purpose flour, unsweetened cocoa powder, baking powder, and salt. Make sure there are no large clumps of cocoa.
- Combine Wet and Dry: Gradually add the dry ingredients to the wet ingredients. Stir gently with a spatula or wooden spoon until just combined. Be careful not to overmix, as this can lead to tough brownies. You’ll know it’s ready when you no longer see streaks of flour.
- Fold in Oreos: Gently fold in 1 cup of the chopped Oreos into the brownie batter. Reserve the remaining ½ cup of chopped Oreos for topping.
- Pour into Pan: Pour the brownie batter into the prepared baking pan, spreading it evenly with your spatula.
- Top with Oreos: Sprinkle the reserved ½ cup of chopped Oreos evenly over the top of the brownie batter. You can lightly press them in if you like, but they will also sink in a bit during baking.
- Bake: Bake for 25-30 minutes, or until a toothpick inserted into the center comes out with moist crumbs attached (not wet batter). Cooking time can vary slightly depending on your oven, so start checking around the 25-minute mark.
- Cool: Let the brownies cool completely in the pan on a wire rack before cutting. This is crucial for achieving clean cuts and the best fudgy texture. Once cooled, use the parchment paper overhang to lift the entire brownie slab out of the pan for easy slicing.

Storing and Reheating Tips
Leftover Easy Oreo Brownies can be stored at room temperature in an airtight container for up to 3 days. For longer storage, refrigerate them in an airtight container for up to a week. The texture may become slightly denser when refrigerated, but they will still be delicious.
To reheat, you have a few options:
- Room Temperature: If you prefer them at room temperature, simply take them out of their storage container about 30 minutes to an hour before serving.
- Microwave: For a warm, gooey treat, microwave individual brownie squares for 10-20 seconds. Be careful not to over-microwave, as this can make them tough.
- Oven: For a slightly crisper edge, reheat individual brownies in a preheated oven at 300°F (150°C) for about 5-8 minutes.
Freezing is also an excellent option for these brownies. Wrap them tightly in plastic wrap, then place them in a freezer-safe bag or container. They will stay fresh in the freezer for up to 2-3 months. Thaw them overnight in the refrigerator or at room temperature before serving.
Final Thoughts
These Easy Oreo Brownies truly deliver on their promise of simple indulgence with spectacular results. Gather your ingredients, spread the batter, and get ready to savor every fudgy, cookie-filled bite. We hope you enjoy making and sharing this delightful treat!
