Slutty Brownies Recipe

Slutty Brownies are the most decadent and outrageous bar cookie you’ll ever try: chocolate chip cookies on the bottom, 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. Almost every blogger has made some version of this recipe but if you’re looking for the BEST Slutty Brownie recipe, look no further.

Chocolate Chip Cookie Layer

• They’re easy cookies that start with melted butter, so you don’t need a mixer.
• Stir together butter, brown sugar, and granulated sugar. Then stir in an egg, vanilla, baking soda, and salt, and then the all purpose flour. Chocolate chips are last – but not least!
• Normally when I make these as cookies you have to chill the dough, but when you’re making cookie bars you can skip that step.

Brownie Layer

My favorite brownie recipe has three important things about it:

1. It’s one bowl, one spoon, no mixer,
2. It has baking chocolate you melt with the butter,
3. AND it has cocoa powder you add after you stir in the sugar and eggs.
4. Once you make the brownie layer, you’re ready to assemble!

Tips for how to make Slutty Brownies

• 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.
• Then, top with about 24 Oreos. I used regular Oreos but you could use double stuff or any flavor you want.
• Top the Oreos with the brownie batter. Spread it evenly to cover the cookies.
