If you’re looking for the ultimate Oreo brownie recipe, you’ve found it. These rich, fudgy brownies combine everything you love about classic chocolate brownies with crunchy chunks of Oreo biscuits for the perfect cookies-and-cream twist.
They’re incredibly chocolatey thanks to both melted dark chocolate and cocoa powder, while the Oreo pieces stay slightly crunchy as they bake, creating the perfect contrast against the gooey brownie centre. Finished with extra Oreos on top, they’re just as impressive to look at as they are to eat.
Whether you’re baking for birthdays, bake sales, family gatherings or simply because you’re craving chocolate, this easy Oreo brownie recipe never disappoints. They’re simple enough for beginner bakers but taste like something you’d find in a bakery.
The best part? They only require a handful of ingredients and come together in one bowl after melting the chocolate and butter.
Butter: adds richness, flavour and helps create that soft, fudgy texture everyone looks for in a great brownie. Using real butter rather than margarine gives a much deeper flavour.
Dark Chocolate: The melted dark chocolate is the heart of these brownies. It creates an intensely chocolatey flavour while also helping achieve that dense, gooey texture.
Caster Sugar: dissolves easily into the eggs, helping create the shiny, paper-thin crackly brownie top that everyone loves.
Eggs: bind everything together while adding structure and creating a rich, chewy texture. Whisking them well with the sugar also helps achieve the signature glossy crust.
Cocoa Powder: Adding cocoa powder intensifies the chocolate flavour without making the brownies overly sweet. It gives them a deep, rich finish.
Plain Flour: Only a small amount of flour is needed. This keeps the brownies dense and fudgy rather than light and cakey.
Oreo Biscuits: Oreos add pockets of crunchy chocolate biscuit and sweet vanilla filling throughout the brownies. Every bite is packed with cookies-and-cream flavour.
Extra Dark Chocolate: Chunks of dark chocolate melt into little pools throughout the brownies, making every slice even more indulgent. You could swap this to milk chocolate if you prefer.
Extra Oreos: Adding whole or halved Oreos on top makes the brownies look bakery-worthy and gives extra crunch after baking.
Don’t overmix the batter. Once you’ve added the flour, fold gently until everything is just combined. Overmixing develops gluten and can make brownies cakey.
Use good-quality dark chocolate. As chocolate is the main flavour, using a high-quality chocolate makes a noticeable difference.
Don’t overbake. Brownies continue cooking as they cool. The centre should still have a slight wobble when they come out of the oven.
Let them cool completely. This is one of the hardest steps, but it’s essential. Cooling allows the brownies to set, making them easier to slice and giving them the perfect fudgy texture.
Use a warm knife to slice. Run a sharp knife under hot water, dry it thoroughly and wipe between each cut for clean, professional-looking brownie squares.
Store correctly. Keep the brownies in an airtight container at room temperature for up to four days. They become even fudgier after the first day.
The ultimate fudgy Oreo brownie recipe that’s rich, gooey and incredibly easy to make.
