This Oreo brownie recipe is seriously one of my most favorite brownies ever – the fudgy factor alone is worth every calorie. The are so fudgy my daughter actually thought they were fudge – that’s how good they are.

I am soooooo a fudgy brownie person. I guess there are two camps of people: fudgy and cakey. These are most definitely NOT cakey brownies. These are ultra-rich, chocolatey, fudgy Oreo brownies.

If you want to learn how to make the best brownies – AND put Oreos in them – then THIS is the recipe you’re looking for.

Easy One-Bowl Brownie Recipe

Use a microwave-safe bowl and you don’t have to worry about using two. Using one bowl means you get a fresh-baked batch of brownies just a little faster and, of course, you’ll have less to clean-up. Because dishes are so not fun.

Every brownie has a layer of Oreos baked in the middle. It’s a little cookies and cream surprise.

Sold yet? I’m telling you – you are going to love these!

How to Make Oreo Brownies from Scratch

This is my basic GO TO brownie recipe, so let’s break down how to make them, and why you never need to buy a box mix again.

Here are the ingredients you need:

  • Chopped unsweetened baking chocolate
  • Chopped semi-sweet baking chocolate
  • Butter
  • Sugar
  • Eggs
  • Vanilla extract
  • Unsweetened Cocoa
  • All-purpose flour
  • Oreo cookies

Baking Chocolate: I like to use a combination of baking chocolates (unsweetened and semi-sweet) but you can use all unsweetened. I don’t recommend using all semi-sweet, but you can in a pinch (the brownies get lots of sugar from the sugar added).

The eggs give this the Fudgy factor times 10. You do NOT need leavening like baking soda or baking powder in brownies, that’s what the eggs are for!

I use regular unsweetened cocoa but you can substitute Special Dark or Dutch Process easily in this recipe.

First, place all of the chopped baking chocolate and butter in a microwave-safe bowl. Heat on high power in 30 second increments, stopping to stir between each, until the mixture is smooth. Depending on your microwave this may take two to three minutes total.

Add the sugar and stir to combine. Add the eggs, vanilla, and cocoa powder and stir well until combined. Add the flour and stir until just combined.

Oreo brownies process

Spread half of the batter into your prepared baking pan. Place the cookies in an even layer over the top and then spoon the rest of the batter over the top of the cookies. Use a spatula to smooth the surface.

Bake the brownies for approximately 33 minutes. To check for doneness, insert a toothpick two inches from the outside of the pan. If it comes out clean, they’re ready!

I know it’s tempting to dig in right away, but let the brownies fully cool before slicing. They will taste even better after they settle and set and it will be a lot easier to get clean slices.

How to Make Them with a Brownie Mix

Of course, I want to encourage you to make them from scratch if you can, but I get it! If you’re short on time or ingredients you can absolutely use your favorite brownie mix to make Oreo brownies.

Just skip everything but the Oreos and make the brownie batter following the package instructions. Spread half of it in the pan, top with cookies, and smooth the rest of the batter over the top.

How to Store Homemade Brownies

In the unlikely event you have leftovers keep them in an airtight container. They’ll stay fresh for three to four days at room temperature or pop them in the fridge and they’ll keep for up to we week.

You can also freeze them. This is particularly helpful if you are like me and can’t trust yourself if they’re just hanging out on the counter. You can wrap them individually and store them in a freezer-bag or container for three months (or longer in most cases!). To thaw, just leave them out at room temperature.

Prep Time 10 minutes
Cook Time 40 minutes
Total Time 50 minutes
Yield 36 brownies
Serving Size 1 serving


  • 2 ounces unsweetened baking chocolate, chopped 56g
  • 2 semi-sweet baking chocolate, chopped 56g
  • 1 cup unsalted butter, sliced 227g
  • 2 2/3 cups granulated sugar 332g
  • 1/4 cup unsweetened cocoa powder 21g
  • 4 large eggs
  • 1 teaspoon vanilla extract 5ml
  • 1/2 teaspoon salt
  • 1 1/3 cup all-purpose flour 165g
  • 24 Oreo cookies


  • Preheat oven to 350°F. Line a 9×13-inch pan with foil and spray with nonstick cooking spray.
  • Place chocolate and butter in a large microwave-safe bowl. Heat on high power in 30 second increments, stirring between each, until chocolate and butter are melted and smooth (about 2 minutes, depending on your microwave).
  • Stir sugar and cocoa into chocolate and butter mixture using a spatula or wooden spoon. Stir in eggs and vanilla, then stir in salt. Mixture will be grainy looking but smooth. Stir in flour carefully.
  • Pour 1/2 of batter into prepared pan. Top with Oreos evenly, then spread the remaining batter in the pan.
  • Bake for 25-35 minutes, or until the top is no longer glossy and a toothpick comes out with just a few crumbs when placed 2-inches from the side of the pan. Cool completely before slicing. I prefer mine baked only 25 minutes; if you want yours less fudgy, bake longer.

  1. Hello! I over-estimated the amount of ganache I needed for a friend’s birthday cake and I CANNOT just throw it away. So, aside from eating it by the spoonful (also not a good idea) I thought a gooey batch of brownies would be a good solution. So, the ganache was 1 cup of cream and 8 oz of semisweet chocolate. Can I use this in place of the chocolate in your Oreo Brownies recipe?
    Wasn’t sure if the addition of the cream (within the ganache) would change the outcome.
    Thanks for your feedback & guidance!

  2. Hi, I was just wondering, isn’t an entire tablespoon of vanilla extract a lot? I’ve only really seen at most two teaspoons of vanilla in most brownie recipes, so I was thinking that this is quite a lot. I’m really looking forward to trying these though! 

    1. It is a lot, but I like vanilla. Feel free to use less, but I always add more when I can!

  3. Hi! Can I use semi sweet chocolate chips instead of the baking chocolate? It’s what I have now in the pantry and I can’t wait to bake this!

  4. OMG! Just use Halloween or Christmas Oreos and BOOM instant holiday dessert! Hmm…me thinks I know what I am bringing home for the holidays!

  5. Your blogger get-together sounds like so much fun, Dorothy! There really is nothing like talking with others who really “get it” ! Extra big bonus that the husbands and kids get along as well. 🙂 I would love to attend a gathering like that in St. Louis. As for these brownie bites…..You reeled me in with Cookies ‘n Cream Kisses (who knew?!) but I fell in love with the Mini-Oreos on the bottom!
