Dense and decadent fudgy brownies + chopped Oreo cookies = the kind of math I can get behind. These easy-to-make treats are based on my go-to brownie recipe from my new cookbook Comfort Baking, but I’m sharing the recipe here today with a cookies-and-cream-flavored twist! Get ready to eat the whole pan of these bars, because they are G-O-O-D.

Fudgy Oreo Brownies Recipe

Even with Halloween on the horizon and all the candy swirling around, there is always space to be made for homemade brownies. These fudgy Oreo brownies are among my new favorite brownies in the whole wide world, and that’s saying something because I, like, really love brownies.

The recipe for these bars is based on my go-to brownie recipe that’s in my new cookbook; the recipe in the book is for Peanut Butter Cup Brownies (!), which are also incredibly delicious, but today I’m sharing this Oreo-stuffed version that’s also topped with a simple icing because I care about you. Here is what you can expect from this recipe:

  • Dense, fudgy texture throughout with a crinkly top
  • Deep and rich chocolate flavor
  • Pockets of cookies and cream goodness
  • A simple powdered sugar icing that adds an extra touch of sweetness
  • With leftover Oreo cookies, try this Oreo Ice Cream Cake

How to Make Really Fudgy Brownies

The trick to making really fudgy, decadent brownies is actually quite simple. You ready for it? Here it is: You need more fat than flour in your recipe. So here, we’ve got melted butter, melted chocolate and several eggs all contributing to the fat category; we’ve only got a little flour and cocoa powder to make up the “flour” side. This ratio will guarantee you a rich, ultra-fudgy brownie that’s moist and chewy and irresistible.

How to Get That Crinkly Top on Your Brownies

Another trick of the trade when it comes to brownies is getting that crinkly top, every time. It’s shiny and pretty and also really delicious when paired with the fudgy center. You’ll need to whisk your eggs really well to get that crinkly top. Yes, that’s really it! Once your eggs are pale yellow and thickened, you’ll know you’ve got it right. And a crinkly top will await you once the brownies are baked. It’s magic — er, science. Maybe both.

How to Store These Brownies

To keep these brownies nice and fresh for several days, I recommend storing them in an airtight container at room temperature for up to 5 days. If you like to have extra-dense brownies, you can store them in the fridge (my husband prefers to eat them cold, and they taste in-credible with a glass of milk). See the Recipe Notes for how to freeze these brownies if you want to save them for way later!
