why you'll love these oreo brookies
- Extra chewy and moist
- You only need 8 ingredients!
- The best of both worlds being half brownie half cookie
- Crushed Oreo pieces in the bar and on top!
ingredient notes
- Unsalted butter: If you substitute it with salted butter you should omit half and salt.
- Eggs: Take the eggs out a few hours before baking so they can come to room temperature. If you forget, place the eggs in a jar or cup and fill it with hot tap water for 5-10 minutes.
- Light brown sugar: The light brown sugar gives the oreo brookies a soft and chewy texture.

instructions
Before you start: Butter an 8x8 baking pan and line it with parchment to hang off the sides, then lightly butter the sides. Preheat the oven to 325F/165C.
Step 1: In a medium mixing bowl, whisk together the melted butter, light brown sugar, and white sugar until combined.
Step 2: Add the eggs to the bowl and whisk to combine.
Step 3: Add the flour, salt, and cocoa powder and whisk to combine.
Step 4: Pour the batter into the baking pan and use a spatula to spread it evenly in the pan. Bake for 15 minutes. Meanwhile, make the cookie dough.
Step 5: In a medium bowl, whisk together the melted butter, light brown sugar, and white sugar until combined. Then add the egg and mix until well combined.
Step 6: Whisk in the flour, baking powder, salt, and ⅓ of the chopped Oreos and mix until just combined.
Step 7: Carefully remove the pan from the oven and add spoonfuls of the cookie dough on top of the brownie layer. Evenly top the cookie layer with the rest of the Oreo pieces, then continue baking for another 25-28 minutes, or until the cookie is a golden brown.
Step 8: Allow the brownie cookies to cool on a wire rack until cool before cutting.
expert baking tips
- Use a kitchen scale: I highly recommend using a kitchen scale to weigh the ingredients. They are very affordable and ensure you have the most accurate measurements when baking!
- Butter the baking pan: Buttering the sides of the pan will keep it from sticking to the pan and making it easier to remove once baked.
- Don't over bake them!: This is the big one! Overbaking the bars will make them dry and crumbly.
- Dark vs. light baking pans: Baking pans conduct heat differently depending on what color the pan is. If your pan is glass or white, you should increase the heat to 350 F/177 C.
storage & freezing
- Room temperature: Store the baked bars in a sealed container at room temperature. They will stay fresh for 2-3 days if stored properly!
- Freezer: Store the baked bars in a sealed container in the freezer for one month.
faq's
When the bars are done, the top of the cookie layer should look golden brown. The dough should be set on top but still soft underneath the crust. They will continue to bake even out of the oven, this will give you gooey bars that stay soft for days!
I have not tested this recipe to be gluten-free but would love to hear how it turns out!

Recipe Notes
- Use a kitchen scale: I highly recommend using a kitchen scale to weigh the ingredients. They are very affordable and ensure you have the most accurate measurements when baking!
- Don't chop the Oreo's too small: If the chunks are too small, you won't get crunchy pieces when you bite into the bars.
- Butter the baking pan: Buttering the sides of the pan will keep it from sticking to the pan and making it easier to remove once baked.
- Don't over mix the batters: Mix the batters just until combined otherwise they will be dense and tough instead of soft and chewy.
- Don't overbake them!: This is the big one! Overbaking the bars will make them dry and crumbly.
Elise says
I loved everything about these brookies! The oreos on top stayed super crunchy even after baking and the bars were so moist and chewy. Everyone loved them!
Brittany Steiger says
I made these for the first time for a super bowl party. Everyone loved them and had a couple each. I like my brownies fudgy, and i like my cookies soft. If you’re careful not to over-bake, these turn out so amazing. The addition of the Oreos just brings them over the top!

Yay! Thanks so much for making them Brittany! 🙂
