Frequently Asked Questions
What are slutty brownies made of?
Slutty brownies are made of three distinct layers. A chocolate chip cookie dough base, a layer of Oreo cookies, and a brownie batter poured over the top and baked together into one pan.
Why are they called slutty brownies?
The playful name comes from how the dessert layers together three separate treats into one indulgent bar. Top slightly warm bars with a scoop of vanilla ice cream, or pair them with our Chocolate Cottage Cheese Ice Cream for an extra creamy chocolate treat.
Can I use a boxed cookie mix or brownie mix instead of making it from scratch?
Yes. If you are short on time, a boxed chocolate chip cookie mix and a boxed brownie mix can be substituted for the homemade layers in this slutty brownie recipe. The results will be slightly different in texture, but still delicious.
Do I need to crush the Oreos or use them whole?
Either works well. Whole Oreos give you a satisfying cookie crunch in the middle layer, while breaking them into pieces helps them spread more evenly across the pan and makes slicing a bit easier. This recipe uses broken pieces for that reason.
How do I know when slutty brownies are done baking?
The brownie top should look set with a light crackle, while a toothpick inserted into the center should come out with a few moist crumbs, not wet batter. Keep in mind the layer underneath the brownie top will still look fudgy, which is exactly what you want.
Can I make slutty brownies ahead of time?
Yes. These bars actually slice more cleanly once they have cooled completely, so making them a few hours ahead or even the night before works great.
How should I store leftover slutty brownies?
Store leftover bars in an airtight container at room temperature for up to three days, or in the refrigerator for up to a week for a firmer, fudgier bite.
Can I freeze slutty brownies?
Yes. Wrap individual bars tightly and freeze them for up to two months. Let them thaw at room temperature before serving.
Can I add other mix ins to this slutty brownie recipe?
Absolutely. Chopped nuts, peanut butter cups, or a swirl of caramel can all be added to the brownie batter before baking. Just keep in mind that extra mix ins may add a minute or two to the baking time, so check for doneness a little earlier than usual.
Notes and Tips
Line the pan with parchment for easy removal, and let the bars cool completely before slicing for clean layers. Spread the cookie dough evenly and avoid overbaking the brownies, as they’ll continue to set while cooling. For more consistent results, measure your flour carefully using the King Arthur Baking flour-measuring guide. Use a sharp, clean knife for neat slices. For extra-gooey slutty chocolate brownies, remove them a couple of minutes early and let them finish setting as they cool. Room-temperature butter and eggs also help everything combine smoothly.
Ingredients
Cookie Dough Layer
1/2 cup unsalted butter, softened 1/2 cup brown sugar, packed 1/4 cup granulated sugar 1 large egg 1 teaspoon vanilla extract 1 1/4 cups all purpose flour 1/2 teaspoon baking soda 1/4 teaspoon salt 1 cup chocolate chips
Oreo Layer
20 to 24 Oreo cookies, broken into pieces
Brownie Layer
1/2 cup unsalted butter, melted 1 cup granulated sugar 2 large eggs 1 teaspoon vanilla extract 1/3 cup cocoa powder 1/2 cup all purpose flour 1/4 teaspoon salt 1/4 teaspoon baking powder
The cookie dough layer forms the sturdy base that holds everything together, while the broken Oreo pieces add crunch and that familiar cookies and cream flavor right through the middle. The brownie layer poured on top is what ties the whole dessert together, turning three separate treats into one rich, fudgy bar once it bakes.
Instructions
1. Make the Cookie Dough and Press It Into the Pan
Cream the softened butter with the brown sugar and granulated sugar until light and fluffy. Mix in the egg and vanilla extract until fully combined. Fold in the flour, baking soda, and salt, then stir in the chocolate chips until a thick cookie dough forms. Press the dough evenly into the bottom of a parchment lined baking pan, smoothing it out with a spatula or your hands so it covers the pan in an even layer.
2. Add the Oreo Layer and Mix the Brownie Batter
Break the Oreo cookies into rough pieces and scatter them evenly across the cookie dough base, covering the surface completely. In a separate bowl, whisk the melted butter and granulated sugar together until smooth. Whisk in the eggs and vanilla extract until the mixture turns glossy and slightly lighter in color. Fold in the cocoa powder, flour, salt, and baking powder until a thick, glossy brownie batter forms.
3. Assemble, Bake, and Slice
Pour the brownie batter evenly over the Oreo layer, spreading it out with a spatula until it reaches the edges of the pan. Bake until the brownie top looks set and slightly crackled and a toothpick comes out with a few moist crumbs. Let the pan cool completely on a wire rack before slicing into bars with a sharp knife, revealing the three distinct layers in every piece.
