I know. Just the name is outrageous. They are described by the original creator of the “slutty brownie” as “oh so easy, and a little bit filthy.” Sorry. I hope you aren’t scandalized, especially since it is a perfectly accurate description.

I went ahead and took the Londoner’s original chocolate chip cookie dough/oreo cookie/brownie concoction and messed with it. Like the original used boxed cookies and boxed brownies, and I went for some favorite homemade varieties. Then I took it one step further and messed with it for Halloween. I couldn’t help myself.

I used my favorite Soft and Chewy Chocolate Chip Cookie recipe. Only, instead of chocolate chips, I chopped up a bunch of Halloween candy (snickers, milky ways and twix bars.)

Then, the cookies that inspired the whole batch of naughtiness, these ridiculous Halloween Oreos.

Then comes the rich and chocolaty chewy Espresso Brownie layer. I’m not kidding.

It’s grossly overindulgent and wonderful at the same time. Mostly wonderful. Maybe even spectacular. My kids are ga-ga for me right now. Your kids/hubby/wife/lovey/boyfriend/girlfriend/friends/neighbors/co-workers will freak too. Enjoy!

This is how you make them:

Preheat the oven to 350 degrees. Prepare an 8×8” baking pan by lining it with tin foil.

Whip up a HALF batch of these Soft and Chewy Chocolate Chip Cookies, only sub the chocolate chips for 1 ½ cups of chopped up candy bars. Set aside.

Now make a half batch of these Espresso Brownies (minus the chocolate chips), and set the batter aside.

Press the cookie dough into the bottom of the pan and smooth the top with a butter knife.

Next, line up 16 Oreo cookies over the cookie dough.

Pour the brownie batter over the top and with a butter knife, spread the batter smoothly.

Place the brownies in the oven and bake for 40-45 minutes.

Place on a rack to cool completely. Slice into 16 brownies. Enjoy!
