Oreo Brookies are the ultimate answer for anyone who can never choose between a chocolate chip cookie and a fudgy brownie. This mashup has been a party hit ever since I made a batch for a rainy day movie marathon with my nieces. Each bite delivers rich brownie satisfaction, buttery cookie chew, and crunchy Oreo pieces all in one treat.
When I baked Oreo Brookies for the first time, I ended up with zero leftovers and three requests for the recipe. This treat is now required at every family get-together.
Ingredients
- Unsalted butter: Room temperature for both doughs gives a creamier texture
- Light brown sugar: Adds moisture and a caramel note to the cookie layer
- Granulated sugar: Sweetens both layers and helps achieve tender crumb
- Large egg yolk: Only the yolk in the cookie dough keeps it extra chewy
- Vanilla extract: Essential for enhancing all the chocolate flavors
- All-purpose flour: Standard base for structure Use fresh flour for best texture
- Fine sea salt: Balances the sweetness and brings out chocolate notes
- Baking soda: Gives the cookie dough its lift
- Oreos: Chopped for big pockets of crunch and chocolate Use fresh for crispness
- Semi sweet chocolate chips: Melts smooth into the brownie batter Use quality chocolate for best flavor
- Unsweetened cocoa powder: Intensifies the chocolate taste Sift before using to prevent lumps
- Large egg: Binds the brownie batter for a fudgy finish
Instructions
- Prepare the Pan and Preheat:
- Line a square 8 inch pan with parchment so it hangs over the edges These flaps will help you lift out the finished brookies Preheat oven to 350 F or 180 C to ensure even baking
- Make Cookie Dough:
- In a large bowl cream together butter light brown sugar and granulated sugar for two minutes until fluffy Mix in egg yolk and vanilla until smooth Gently fold in flour salt baking soda and chopped Oreos just until blended

- Assemble in Pan:
- Scoop generous two tablespoon portions of cookie dough and drop them spaced apart in the pan Fill the alternate spots with scoops of brownie batter Gently press cookie dough mounds so heights are even with brownie batter
- Finish and Bake:
- Scatter extra chopped Oreos across the top Bake for 25 to 27 minutes or until the cookie section is golden brown and a toothpick in the brownie comes out with a few moist crumbs After 20 minutes loosely tent with foil to avoid over browning cookies Let cool before lifting out to slice

Oreos are not just a mix in here They create those signature crunchy pockets which everyone picks for first If you let little hands help with the Oreo add ins you will make a serious memory
