These Cookies & Cream Oreo Stuffed Brownies are decadent and completely outrageous. A chewy brownie base, stuffed with Oreos and topped with melted candy bar! They’re insanely good!

Oh. My. Heck! These Cookies & Cream Oreo Stuffed Brownies might just be the most scandalous brownies I’ve ever eaten. A chewy, dense brownie base studded with chocolate chips, Double Stuf Oreos pressed on top and then finished off with melted Cookies ‘n’ Creme and Candy Bars . . . .they’re ridiculous!

I mean, just look at them! Are you drooling? They’re unlike any brownies I’ve ever made or eaten. They’re everything a brownie should be. . .rich, dense, fudgy, loaded with chocolate chips, etc. All diets go out the window for the day with these babies.

It’s kind of funny that I love these so much because Cookies ‘n’ Creme candy bars have never been a candy bar that I would just buy to eat. Buuuut, boy do they ever make killer some desserts! After you give these brownies a try, you need to make my Cookies & Cream Blondies, they’re my most requested treat ever by friends and family.

Find any excuse to make these brownie . . . a BBQ, a potluck, a family party, a Wednesday, a Saturday, etc. You’ll be so glad you did!

CAN I USE REGULAR OREOS INSTEAD OF DOUBLE STUF?

Of course you can, but why would you want to (haha)?! No, but really, if you prefer regular Oreos over the Double Stuf Oreos, go head and use them.

CAN I USE A BOX BROWNIE MIX INSTEAD?

Yes you can. The original recipe actually calls for a box mix, but I like to use my favorite chewy brownie recipe for these brownies. When I’m in a hurry, then a box brownie mix always comes in handy. Trust me, I have nothing against them! You can even use your own brownie recipe if you’d like, just make sure you adjust it for an 8×8 pan.

Cookies & Cream Oreo Stuffed Brownies

Ingredients

BROWNIE LAYER:

2 1/2 tablespoons Dutch-processed cocoa
1/4 cup plus 1 tablespoon boiling water
1 ounce unsweetened chocolate, chopped fine
1/4 cup plus 1 tablespoons vegetable oil
2 tablespoons butter, melted
1 large egg
1 large yolk
2 teaspoons vanilla extract
1 1/4 cups sugar
3/4 cup plus 2 tablespoons all-purpose flour
1/4 teaspoon salt
1/2 cup chocolate chips (milk or semisweet)
1 (18-oz.) box brownie mix, plus ingredients called for on box
16 Double Stuf Oreos
6 (1.55 oz) Hershey's Cookies 'n' Creme Bars
Melted chocolate, for drizzling (optional)

Instructions

BROWNIES:

Preheat oven to 350 degrees. Line a 8x8 inch pan with foil and spray with nonstick cooking spray.
Whisk cocoa and boiling water together in large bowl until smooth. Add unsweetened chocolate and whisk until chocolate is melted. Whisk in oil and melted butter (mixture may look curdled, but don't worry.) Add the eggs, egg yolk, and vanilla and continue whisking until mixture is smooth.
Whisk in sugar until fully incorporated. Add flour and salt and fold in with a rubber spatula until combined. Fold in chocolate chips.
Spread batter evenly into prepared pan. Evenly place Oreos on top (4x4 row) and press Oreos into the batter.
Bake 28-33 minutes or until a toothpick inserted into center comes out mostly clean. Let cool completely.
Place unwrapped candy bars in a medium microwave-safe bowl. Microwave for 1 minute then stir, continue cooking in 15 second increments until melted. Pour over cooled brownies smooth into an even layer using an offset spatula,.

TOPPING:

Refrigerate until set, about 0 minutes, then drizzle with melted chocolate, if using, and slice into squares.

Recipe Notes

Don't let the melted candy bar harden too much or when you cut them it will break into pieces. I like to let them sit in the fridge about 8 to 10 minutes, then score the top all the way through the candy bar layer and then refrigerate for 15 -20 more minutes.

You can use a boxed brownie mix (18 oz box) if you'd like or your favorite brownie recipe. Just be sure you cut it down if you need to for an 8x8 pan.
