Okay, I have to give my oldest son credit for this recipe! In high school, he made these Oreo brownies with Golden Oreos and Reese's Pieces for a soccer party. This fun dessert was a hit with the whole team!
We've been making these ever since, and they're always one of the first desserts to disappear at a party. I mean, who doesn't love biting into a brownie and finding a whole layer of cookies hiding in the middle?! It gets everyone's attention, and then they usually go back for another piece.
And the best part? You only need a few simple ingredients to make a seriously fun dessert. I'd say my son was onto something with this one! Sometimes the easiest recipes really are the best ones.
Why You'll Love These Stuffed Golden Oreo Brownies
- Only 3 ingredients and so easy. This is one of those recipes you can make in minutes!
- That surprise Oreo layer. There's something so fun about biting into fudgy brownies and finding a whole cookie hiding in the middle.
- The crunch on top. The candies add a fun pop of color and just the right amount of peanut butter crunch.
- A fun dessert without the fuss. They look extra special when you cut into them, but they are so easy to make.
Ingredients Needed
You only need three basic ingredients for these fun, delicious brownies. Scroll down to the recipe card for the exact amounts.
- Boxed Brownie Mix: Use your favorite store-bought brand or homemade brownies. Baking times vary by brand, so keep an eye on them as they bake. I love using an Aldi brownie mix for these.
- Golden Oreos: These add a sweet vanilla layer in the center of the dessert. You'll need enough to cover the bottom of a 9x13 pan in a single layer, which is about 24 cookies.
- Reese's Pieces: These add a little peanut butter flavor, some crunch, and a fun pop of color. You could also use peanut butter chips.
Brownie Variations
- Use different Oreo cookies. Use regular Oreos for more chocolate flavor, or try peanut butter Oreos for more peanut butter goodness.
- Add Reese's peanut butter cups. Chop up the candies, then stir them into the brownie batter before baking.
- Make a smaller batch. Use an 8x8 pan for thicker, fudgier brownies. Keep an eye on them, as the baking time will be longer.
How To Make Reese's Pieces Brownies
These brownies are so easy to put together. Layer the batter, cookies, and candies, then let the oven do the rest.
- Make the brownie mix. Mix the batter in a large bowl following the package directions. Spread half the batter into a prepared pan.
- Add the Oreos. Arrange the cookies in a single layer over the batter, pressing them down slightly. Keep them close together so you get a cookie in every bite.
- Cover with the remaining batter. Gently spread the rest of the mixture over the cookies, making sure they are completely covered.
- Add the Reese's Pieces. Sprinkle the candies generously over the top and gently press them down into the thick batter so they stay put as the brownies bake.
- Bake. Place the pan in the oven and bake until a toothpick inserted in the center comes out with a few moist crumbs. Timing will vary by brand.
BruCrew Tips
- Line the pan with parchment paper. This makes it much easier to remove the brownies. Just lift the whole thing out, then cut into squares.
- Be gentle with the top layer. Take your time and work gently when spreading the brownie mix over the Oreos so the cookies stay put.
- Keep an eye on the baking time. Brownie mixes can bake a little differently from brand to brand, so start checking a few minutes early with a toothpick.
- Let them cool completely. I know it's hard to wait, but cutting into warm brownies will leave you with a mess instead of nice, clean squares.
Storing and Freezing
Keep the cooled brownies in a tightly covered container on the counter for 2-3 days or in the fridge for up to 5 days.
They also freeze really well for a few months. Wrap individual brownies in plastic wrap, then place them in an airtight container or freezer-safe bag. Just thaw to room temperature when the cravings hit!

These look amazing! The vanilla oreos are pretty much the most addictive substance known to man.

Jocelyn, now that I'm back to work at the girls' elementary school I can finally delve back in to making all the recipes that I dare not make, lest I devour the goods myself, during the summer. The teachers are going to flip for these!
Thank you for your support and contributions to "A Little Birdie Told Me..."!
