How to Make the Recipe

Step 1

Preheat your oven to 350°F (175°C). Line a 9×13-inch baking pan with parchment paper.

Step 2

Make the cookie dough: In a large bowl, cream together softened butter, brown sugar, and granulated sugar. Beat in the egg and vanilla extract.

Step 3

Whisk together flour, salt, baking powder, and baking soda. Gradually add to the wet ingredients. Stir in chocolate chips and quick oats until combined.

Step 4

Press the cookie dough evenly into the bottom of the prepared pan to form the first layer.

Step 5

Arrange a single layer of chocolate sandwich cookies over the cookie dough, covering the surface.

Step 6

Make the brownie layer: Whisk melted butter with both sugars and vanilla. Stir in cocoa powder, flour, espresso powder, salt, and baking powder. Beat in the eggs until smooth, then fold in chocolate chips.

Step 7

Pour the brownie batter over the cookie and Oreo layers, spreading evenly.

Step 8

Bake for 35–40 minutes or until a toothpick inserted comes out with a few moist crumbs. Let cool completely before slicing.

Tips for Making the Recipe

Use Room Temperature Ingredients

Helps everything mix evenly, especially the butter and eggs.

Don’t Overmix

Especially in the brownie layer—mix until just combined to keep it fudgy.

Let Cool Before Cutting

The layers need time to set up for clean slicing and the best texture.

Use a Metal Pan

A metal pan conducts heat better and gives more even baking results.

Line with Parchment

Make for easier removal and cleaner cuts.

How to Serve

Cut into squares or bars and serve at room temperature or slightly warmed with a scoop of vanilla ice cream. Drizzle with chocolate sauce or top with whipped cream for an extra special presentation. Ideal for dessert tables, birthday parties, or a weekend baking treat.

Make Ahead and Storage

Storing Leftovers

Store in an airtight container at room temperature for up to 3 days, or refrigerate for up to a week.

Freezing

Wrap individual bars tightly in plastic wrap and foil, then freeze for up to 2 months. Thaw at room temperature or microwave briefly.

Reheating

Microwave slices for 10–15 seconds for that just-baked, gooey texture.
