Ingredients for the Brownies
For the brownies, you will need:
- 1 box of dark chocolate or fudge brownie mix
- Eggs, oil, and water as specified in the brownie package instructions (for this recipe, I used 1/4 cup of water, 1/2 cup of vegetable oil, and 2 eggs)
- 2 tablespoons of molasses
For the cookies, gather the following ingredients:
- 1/2 cup of bread flour
- 3/4 cup + 2 tablespoons of all-purpose flour
- 1 stick of salted butter
- 2 tablespoons of vegetable oil
- 3/4 cup of dark brown sugar
- 1/4 cup of white sugar
- 1 teaspoon of vanilla extract
- 1/2 teaspoon of baking soda
- 1/2 teaspoon of salt
- 1 egg
- 1 and 1/4 cups of crushed Oreo cookies (approximately 13 cookies)
The combination of these ingredients will create a treat that is not only delicious but also texturally interesting, with the soft brownie base complemented by crunchy Oreo cookie pieces.
Step-by-Step Directions
-
Preheat Your Oven: Start by preheating your oven to 350 degrees Fahrenheit. Choose an 8×8 or 9×9 baking dish and grease it or spray it with cooking spray to prevent sticking.
-
Prepare the Brownies: In a larger bowl, add the brownie mix along with the eggs, water, and oil as indicated on the package. Stir until combined and then add the molasses, mixing until it’s thoroughly incorporated. Pour the brownie batter into the prepared baking dish and bake it in the oven for 20 minutes.
-
Make the Cookie Dough: While the brownies are baking, begin preparing the cookie dough. In a saucepan, melt the stick of butter on medium or medium-high heat. Once melted, keep whisking, and let it simmer for about 4-5 minutes until it turns a caramel brown color and releases a rich, nutty aroma. This is the crucial step of browning the butter. Transfer the browned butter into a heat-safe bowl to cool slightly.
-
Blend the Dry Ingredients: While the butter cools, combine the bread flour, all-purpose flour, baking soda, and salt in a medium bowl. Whisk these dry ingredients together to ensure they are blended evenly.
-
Combine Wet and Dry Ingredients: Once the butter has cooled enough that it’s warm (not hot), mix the vegetable oil, brown and white sugars, vanilla extract, and egg into the bowl with the butter. Stir until combined.
-
Prepare the Oreo Cookies: Crush the Oreo cookies using a Ziploc bag, food processor, or a blender. Aim for a mix of fine crumbs and larger pieces to provide texture in your cookie dough.
-
Combine Everything: Add the flour mixture to the bowl with the butter mixture and stir until fully combined. Then, fold in the crushed Oreo cookies, ensuring they are evenly distributed throughout the dough.
-
Layer and Bake: After 20 minutes of baking the brownies, carefully remove them from the oven and evenly spread the cookie dough over the brownie layer. Return the dish to the oven and bake for an additional 25 minutes, or until the cookie dough is set. Let cool, cut, and enjoy!
Tips & Tricks
- Browning the Butter: Keep a constant watch over the butter while it browns, as it can quickly go from perfect to burnt. Stir continuously to prevent scorching.
- Cookie Crumbs: For an extra textural twist, you can reserve a few Oreo chunks to sprinkle on top of the cookie layer before baking. This creates a visually appealing finish.
- Experiment with Flavors: Feel free to add chocolate chips or nuts into the cookie dough for added flavor and texture.
Serving Suggestions & Pairings
Oreo Cookie Brownies are perfect for any occasion. Serve these delightful treats at birthday parties, bake sales, or family gatherings. They pair wonderfully with a scoop of vanilla ice cream or a dollop of whipped cream on the side. A drizzle of chocolate or caramel sauce can also elevate the presentation and bring an extra touch of sweetness.

FAQs
-
Can I use homemade brownie recipes instead of a box mix?
Absolutely! You can use your favorite homemade brownie recipe, just ensure it has a similar baking time and consistency. -

If you don’t have molasses on hand, you could use honey or maple syrup, but keep in mind this may slightly alter the flavor. -
How can I tell when the brownies are done baking?

What’s the best way to cut the brownies?
