Slutty Brownies Recipe

Slutty Brownies are the most decadent gooey brownie and outrageous bar cookie you’ll ever try: chocolate chip cookies on the bottom, fudgy chocolate brownies on the top, and Oreos in the center. Normally this recipe is made with pre-packaged dough and box mixes but my recipe is completely from scratch. I don’t know who came up with the horrible name, but these are really EPIC brookies.

How to Make a Slutty Brownie Recipe

1. You need to make brownie batter and chocolate chip cookie dough – luckily both of those have overlapping ingredients.
2. For the brownie layer you’ll need baking chocolate (unsweetened) and cocoa powder (unsweetened; you can use Dutch Process Cocoa).
3. For the cookie dough layer you’ll need brown sugar as well as granulated, and baking soda too.
4. I always put the fudgy brownies on the bottom with a layer of Oreo cookies in between that and the cookie layer.
5. I always line my pan with parchment paper or tin foil for easy removal.

Storing Instructions

• Store cooled Slutty Brownies in an airtight container on the counter.
• You can freeze them for up to 3 months. Learn how I freeze all my desserts!

Expert Tips

• You’re going to want a metal 9×13-inch pan for this recipe.
• You can also make these in muffin tins if you want Oreo Cookie Brownie Cupcakes!
• I like to cover the pan with foil and spray with nonstick cooking spray to make removal and slicing easier.
• These take quite a long time to bake because they’re so thick. You know brownies are done when the top is solid and no longer wet looking. The toothpick test can be done 2 inches from the edge, but it’s best to use your eyes for this.
• Cool completely before slicing.

Recipe Notes

• You’re going to want a 9×13-inch pan for this recipe, one with 2″ sides. Use metal or glass, whichever you prefer.
• You can also make these in muffin tins if you want Oreo Cookie Brownie Cupcakes!
• I like to cover the pan with foil and spray with nonstick cooking spray to make removal and slicing easier.
• First, press the chocolate chip cookie dough into the bottom of the pan.
• I used regular Oreos but you could use double stuff or any flavor you want.
• Peanut Butter Cup Slutty Brownies: use regular size peanut butter cups instead of the Oreos.
• Use Peanut butter cookie dough or peanut butter chocolate chip cookies instead of the chocolate chip cookies.

1. Melt butter and stir in both sugars in a large bowl. You don’t need to use an electric mixer, but you can. Stir in egg, baking soda, salt, and vanilla extract.

2. Stir in flour then stir in chocolate chips. At this point, you’ll press the dough into the bottom of a 9×13-inch baking dish.

3. Melt baking chocolate and butter until smooth. Make sure to use a large bowl that is microwave safe, and stir every 30 seconds while melting.

4. Stir in the sugar, cocoa, salt, and eggs until smooth. No mixer needed unless you want to use one! Then stir in the flour.

5. Place a layer of Oreos evenly over the cookie dough in the baking pan.

6. Carefully spread the brownie batter over the top of the Oreos in an even layer. Then bake until the brownies are no longer glossy on top.
