What Are Slutty Brownies?

This popular brownie is originally credited to a blog named Kevin & Amanda, which published the a recipe for Cookie Dough Oreo Brownies in 2011. The internet renamed these triple-decker brownies “Slutty Brownies” and the recipe went viral.

What led them to be called slutty brownies? Well, to quote Jessica Simpson on the Jay Leno Show, “I guess a lot goes into them”. Ahem. 😆 Don’t let the scandalous name detract from the deliciousness of these brownies, though. They’re seriously incredible!

How to Make Slutty Brownies

There’s some serious chocolate going on in these brownies. They’re also so easy to make:

Make the Chocolate Chip & Oreo Cookies Layers

First you are going to make the cookie layers:

  • Make the chocolate chip cookie layer. Begin by whisking together the dry ingredients. In a separate bowl, beat the butter and sugars until fluffy, then mix in the egg and vanilla. Add the dry ingredients, mix, then fold in chocolate chips. Press the cookie dough into the bottom of a 9×9-inch pan lined with parchment paper.
  • Add Oreos. Arrange the Oreo cookies in a single layer over top of the cookie dough.

Add the Chocolate Brownie Layer

Next, it’s time to prepare an easy brownie batter, and then get these brownies into the oven!

  • Make the brownie batter. Mix the dry ingredients and wet ingredients separately, then sift the dry into the wet ingredients before stirring to combine.
  • Add to the pan. Spread the brownie batter over the layer of Oreos.
  • Bake. Bake your slutty brownies at 350ºF for 40-45 minutes. Check that the brownies are done by sticking a toothpick into the middle of the pan. If the toothpick comes out clean, they’re ready to come out. Let the cookies cool completely before cutting them into squares.

Can I Use Brownie Mix or Store-Bought Cookie Dough?

Absolutely. If you’re in a pinch, you can make the brownie layer using your favorite boxed brownie mix instead. Just be sure to pick up any ingredients you’ll need to make the brownies as listed on the box. You can even make the chocolate chip cookie layer with store-bought refrigerated cookie dough, too.

Variation Ideas

Try these fun and easy ways to change up the flavors in your slutty brownies:

  • Peanut Butter – Make a variation with peanut butter cookie dough.
  • Replace the Oreos – In place of Oreos, layer Golden Oreos. You can also try this recipe with Nilla Wafers, Chips Ahoy cookies, Graham crackers, or Maria Cookies.
  • Add Frosting – Add some vanilla buttercream or even peanut butter frosting on top. The simple chocolate frosting from my zucchini brownies recipe would work too.

Serving Suggestions

Slutty brownies are so easy to make and they’re always a hit at potlucks and parties. Try these fun and easy ways to serve homemade brownies: 

  • Warm with ice cream. A few seconds in the microwave is all it takes to turn these chocolate brownies into an ooey-gooey treat, perfect for topping with a scoop of vanilla ice cream.
  • Drizzled with chocolate sauce.
  • Make a brownie sundae. Combine both of the ideas above into a decadent brownie sundae, complete with ice cream, whipped cream, chocolate sauce, and a cherry!

How to Store

  • Counter: To keep these slutty brownies soft and chewy, store them at room temperature, either tightly wrapped in plastic wrap or sealed inside an airtight container.
  • Freezer: Slutty brownies freeze well. Simply wrap them airtight and store them frozen for up to 3 months. Thaw the brownies in the fridge before serving.
