Air Fryer Slutty Brownies

I love making Air Fryer Slutty Brownies because cookie, Oreo, and brownie all come together in one pan and the result is just completely outrageous in the best way. The chewy chocolate chip cookie layer goes down first, then a full row of Oreos, then a rich, dense dark chocolate brownie poured right on top, and the air fryer bakes all three layers together quickly and evenly. Every slice is layered, rich, and deeply chocolatey from top to bottom. I make them for potlucks, birthday parties, and game day because they travel well and never last long on the table.

Transfer the mixture to the prepared baking dish. Arrange all the Oreos on top.
24 Oreo cookies
In a big bowl, melt the butter and chocolate together (microwave in 1 min increments, or place the bowl in a double boiler).
½ cup unsalted butter, 6 ounces dark chocolate
Add the sugar and eggs and mix until fully combined and shiny.
½ cup granulated sugar, 2 eggs
Add the flour, cocoa powder and salt and mix until just combined - don't over mix.

Pour the brownie mixture on top of the Oreo cookies.
Bake in the air fryer for 15 minutes at 325°F (160ºC), or until a toothpick comes out dry.
Let it cool and serve.

Notes

Here are a few tips I've picked up from making these bars more than once.

Use room temperature butter: Cold butter won't cream properly, so pull it out at least 30 minutes before you start for both the cookie and brownie layers.
Don't overmix the brownie batter: Once you add the flour and cocoa powder, mix only until just combined. Overmixing develops gluten, resulting in a tougher, less fudgy brownie.
Press the cookie dough evenly: Use clean hands or the bottom of a flat glass to press it into an even layer so it bakes uniformly throughout.
Cover the pan fully with Oreos: Arrange the Oreos in a single, tight layer, with as few gaps as possible, so every bar gets an even stripe of cookie in the middle.
Check with a toothpick: Air fryers can run slightly differently in power, so start checking at the 13-minute mark. The toothpick should come out dry, not just clean of wet batter.
Freeze bars individually for easy grab-and-go: Once fully cooled, flash freeze the sliced bars on a baking sheet for 1 hour before transferring to a freezer bag so they don't stick together.
