Oreo Brookies are the ultimate dessert mash-up—part chewy cookie, part fudgy brownie, and loaded with chunks of Oreo cookies. Every bite gives you crispy cookie edges, gooey brownie centers, and that classic Oreo crunch. They’re surprisingly easy to make and perfect for parties, bake sales, or anytime you’re craving something extra indulgent.
6 tbsp unsalted butter, room temperature
½ cup packed light brown sugar
⅛ cup granulated sugar
1 large egg yolk, room temperature
1 tsp vanilla extract
¾ cup + 2 tbsp all-purpose flour
½ tsp fine sea salt
½ tsp baking soda
4 Oreos, chopped (plus more for topping)
4 tbsp unsalted butter
⅓ cup semi-sweet chocolate chips
¼ cup + ⅛ cup granulated sugar
1 large egg, room temperature
1 tsp vanilla extract
¼ cup all-purpose flour
¼ cup unsweetened cocoa powder
¼ tsp fine sea salt
Line an 8×8 inch baking pan with parchment paper, leaving overhang on all sides.
Preheat the oven to 350°F (180°C).
Cream together the butter, brown sugar, and granulated sugar for about 2 minutes, until light and fluffy.
Mix in the egg yolk and vanilla extract.
Fold in the flour, salt, baking soda, and chopped Oreos until the dough comes together.
Set aside.
Melt the butter and chocolate chips together until smooth. Set aside to cool slightly.
In another bowl, whisk the sugar, egg, and vanilla for about 2 minutes until pale and slightly fluffy.
Slowly pour in the melted chocolate mixture and mix gently.
Fold in the flour, cocoa powder, and salt until just combined.
Scoop 2-tablespoon portions of cookie dough around the pan.
Spoon the brownie batter into the empty spaces between the cookie dough.
Lightly press the cookie dough down so both batters are even in height.
Sprinkle extra chopped Oreos over the top.
Bake for 25–27 minutes, or until:
the cookie dough is golden brown
a toothpick in the brownie section comes out with a few moist crumbs
Tip: After 20 minutes, loosely cover the pan with foil to prevent over-browning.
Let cool completely before slicing for clean edges.
Don’t overmix either batter—this keeps the cookie soft and the brownie fudgy.
Room temperature eggs help everything blend smoothly.
Let them cool fully before cutting so the layers set properly.
Use different Oreos (Double Stuf, Golden, Mint) for fun flavor twists.
Add chocolate chips on top for extra gooeyness.
