How to Make the Recipe

Step 1: Preheat and Prepare

Preheat your oven to 350°F (175°C). Line a 9×9 or 8×8-inch baking pan with parchment paper or lightly grease.

Step 2: Layer the Cookie Dough

Press the entire roll of chocolate chip cookie dough evenly into the bottom of the prepared pan to form the first layer.

Step 3: Add the Oreos

Place a single layer of Oreos on top of the cookie dough. It’s okay if they’re snug—try to cover as much surface as possible.

Step 4: Mix the Brownie Batter

Prepare the brownie batter according to the box instructions using the egg, oil, and water. Stir until smooth.

Step 5: Pour and Spread

Pour the brownie batter evenly over the Oreo layer. Use a spatula to smooth it out, covering all the cookies.

Step 6: Bake

Bake for 35–40 minutes or until the top is set and a toothpick comes out mostly clean with a few moist crumbs. Let cool completely in the pan.

Step 7: Slice and Serve

Once cooled, lift the brownies out of the pan using the parchment paper. Slice into squares and enjoy the layered goodness!

Tips for Making the Recipe

Don’t overbake—slightly underbaking keeps the brownies fudgy and soft.
Let them cool fully before slicing to keep the layers intact.
Use a sharp knife and clean it between cuts for neat slices.
Chill before cutting if you want perfect squares for presentation.
Store extra brownies in an airtight container to keep them moist.

How to Serve

Serve warm with a scoop of vanilla ice cream and drizzle of chocolate syrup.
Top with whipped cream and crushed Oreos for a brownie sundae.
Cut into small bites and add to dessert trays or charcuterie boards.
Serve with coffee or milk for the ultimate cozy treat.
Stack and wrap them as edible gifts for friends or holidays.

Make Ahead and Storage

Storing Leftovers

Store brownies in an airtight container at room temperature for up to 4 days. For longer freshness, keep them in the fridge for up to a week.

Freezing

Wrap individual squares in plastic wrap and freeze in a sealed bag for up to 2 months. Thaw in the fridge overnight or microwave for 15–20 seconds to enjoy warm.

Reheating

Microwave a slice for 10–15 seconds to make the cookie dough and brownie layers warm and gooey again.
