Instructions
1
Warm your oven to 350°F. Put parchment paper in an 8x8 inch baking dish with paper hanging over sides so you can pull out brownies later.
2
Grab a microwave-safe bowl and throw in the butter, vegetable oil, regular sugar, and brown sugar. Heat them in 30-second bursts, giving it a good stir each time. After everything's melted, nuke it one more minute. Stir it really well until sugar isn't grainy anymore.
3
Drop in cold eggs one by one, mixing well after each. Stir in the vanilla until you notice the mix starts pulling away from the bowl sides a bit.
4
Sift your flour, cocoa powder, and salt right into the mix. Fold it all together just until mixed. Don't go crazy with the stirring.
5
Pour half your brownie mix into the pan and smooth it out. Place 15 Oreos flat across the batter in a single layer.
6
Dump the rest of your brownie batter on top of the Oreos. Make sure they're totally hidden and the top looks nice and even.
7
Sprinkle those 5 crushed Oreos all over the top. Stick it in the hot oven for 30 to 45 minutes. You'll know it's done when a toothpick comes out with some moist crumbs on it.
8
Put the pan on a wire rack and let everything cool down completely. Then grab those parchment edges and lift the whole thing out. Cut it up into squares and enjoy.
Essential Tips
Room temp eggs
Take the eggs out of the fridge 15-20 minutes before baking. Cold eggs can seize the butter and oil, making the batter lumpy and dense instead of smooth and fudgy.
Don't overmix
Fold the dry ingredients into the wet just until combined. Overmixing develops gluten, which can make your brownies tough instead of tender and chewy.
Even Oreo placement
Press the whole Oreos gently into the first layer of batter to prevent them from sinking or shifting during baking. Arrange them in a grid for even coverage.
Check at 30 minutes
Start checking for doneness at 30 minutes using the toothpick test. Overbaking dries out brownies, while underbaking leaves them gooey in the center-but that's sometimes preferred!
Parchement overhang
Use an 8x8-inch pan with parchment paper hanging over the sides. This makes lifting and slicing the brownies effortless and mess-free, especially when serving at a party.
Smart Swaps & Variations
Gluten-free
Swap all-purpose flour for a 1:1 gluten-free flour blend. Ensure the Oreos used are gluten-free, as some varieties contain wheat.
Vegan
Use vegan butter, a flax egg (1 tbsp ground flaxseed + 3 tbsp water), and dairy-free chocolate Oreos. Replace butter with coconut oil for a firmer texture.
Peppermint twist
Add 1/2 teaspoon peppermint extract to the brownie batter and top with crushed candy canes or peppermint Oreos for a festive holiday twist.
Salted caramel
Place 5-6 salted caramel candies between the whole Oreos and the second layer of batter for a sweet and salty surprise in every bite.
Mini brownie bites
Bake in a mini muffin tin lined with mini cupcake liners for single-serve brownie bites perfect for parties or gifting.
What to Serve With This
- A glass of cold milk or almond milk for dipping, balancing the richness of the brownies.
- Whipped cream and a drizzle of chocolate sauce for an extra-decadent dessert platter.
- Vanilla ice cream or chocolate gelato for a brownie sundae that's sure to impress.
- Hot spiced apple cider or pumpkin spice latte for a cozy autumnal pairing.
Storage & Reheating
Storage
Store brownies in an airtight container at room temperature for up to 5 days. For longer storage, refrigerate for up to 1 week or freeze for up to 3 months.
Reheating
Reheat individual slices in the microwave for 10-15 seconds to restore warmth and softness. For best texture, warm the entire pan in a 300°F oven for 5-10 minutes, covered with foil.
Expert Chef Tips
- Press the whole Oreos into the first layer of batter before adding the second layer to prevent them from floating or breaking apart during baking.
- Use a serrated knife dipped in hot water to slice the brownies cleanly, especially when cutting chilled brownies for a neater presentation.
- For a glossier, bakery-style finish, brush the top of the brownies with a thin layer of melted chocolate or ganache before adding the crushed Oreo topping.
Equipment You’ll Need
- 8x8-inch baking pan
- Parchment paper
- Medium microwave-safe bowl
- Whisk or spatula
- Toothpick or cake tester
- Rolling pin or food processor (for crushing Oreos)
Nutritional Benefits
- Each serving (1 brownie) contains approximately 430 calories, primarily from carbohydrates and fats due to the butter, oil, and sugar in the recipe.
- The Oreos contribute added sugars and saturated fats, so enjoy these treats in moderation as part of a balanced diet.
- Brownies provide small amounts of iron from the cocoa powder and some fiber from the flour, though the overall fiber content is low due to the rich ingredients.
- For a lighter option, reduce the sugar by 1/4 cup and use dark chocolate Oreos to cut some of the sweetness while adding antioxidants.

Frequently Asked Questions
Can I use a different size pan?
Yes, but adjust the bake time accordingly. For a 9x9-inch pan, check for doneness 5-10 minutes earlier. For a 7x7-inch pan, bake closer to 40-50 minutes. The brownies will be thicker and may require more time.
What's the best way to crush Oreos evenly?
Place Oreos in a ziplock bag and roll a rolling pin over them. For finer crumbs, pulse them in a food processor for 10-15 seconds. Avoid over-processing, or you'll end up with a paste.
Can I make this recipe ahead of time?
Absolutely! Bake the brownies up to 2 days ahead and store them at room temperature in an airtight container. Refrigerate for longer storage. Slice just before serving to maintain freshness.
Why did my brownies turn out dry?
Overbaking is the most common cause. Start checking for doneness at 30 minutes, and remove the brownies as soon as a toothpick comes out with a few moist crumbs. Also, ensure you're measuring flour correctly-spoon and level, don't scoop.
Can I substitute another cookie for Oreos?
Yes! Try chocolate sandwich cookies like Hydrox or homemade chocolate cookies. For a nutty twist, use peanut butter cookies or pecan sandies. Avoid soft cookies like snickerdoodles, as they may not hold up as well.
How do I prevent the Oreos from sinking?
Press the whole Oreos firmly into the first layer of batter to anchor them. Avoid overmixing the batter after adding the Oreos, as this can cause them to sink. Chilling the batter for 10 minutes before baking also helps.
Can I add other mix-ins to the brownie batter?
Of course! Chocolate chips, toffee bits, or chopped nuts work well. Add them to the batter after folding in the dry ingredients, but before pouring it into the pan. Keep mix-ins to 1/2 cup total to avoid overcrowding.
Why do my brownies have a crackly top?
The crackly top is caused by the sugar and eggs creating a thin crust as the brownies bake. This is normal and desirable! To enhance it, whisk the eggs and sugars vigorously before adding the butter and oil.
