How to Make Slutty Brownies
This dessert is all about layering and baking to just the right consistency. First, you’ll prepare the brownie mix by combining it with melted butter, eggs, and water. Spread half of it into your pan, then arrange a full layer of chocolate sandwich cookies over the top. Next comes the cookie dough — gently pressed to cover the cookies. The final step is adding the remaining brownie batter.
Once it’s all in the pan, you’ll bake until the top is set and a toothpick comes out with a few moist crumbs. After baking, let the pan cool fully before cutting the bars into squares.
Step-by-Step Instructions
- Preheat Your Oven
Preheat to 350°F (175°C). Grease a 9×13-inch baking dish and line it with parchment paper for easier cleanup and slicing. - Make the Brownie Batter
In a large bowl, combine the brownie mix, melted butter, eggs, and water. Stir until the batter is smooth and lump-free. - Layer the Brownie Base
Pour half of the batter into the prepared dish. Use a spatula to spread it evenly across the bottom. - Add the Cookie Layer
Place your chocolate sandwich cookies in a single layer over the brownie batter, making sure they’re evenly spaced. - Spread the Cookie Dough
Scoop out chunks of the cookie dough and gently press them over the cookies to cover the entire surface. - Top with Remaining Brownie Batter
Pour the rest of the brownie batter over the cookie dough. Smooth the top with a spatula without pressing too hard. - Bake to Perfection
Place in the oven and bake for 30 to 35 minutes. The top should look set, and a toothpick should pull out moist crumbs (not raw batter). - Cool Before Cutting
Let the pan cool completely. For cleaner edges, chill the brownies in the fridge for 30 to 60 minutes before slicing into squares.
Helpful Tips
- Don’t overmix the batter: Mix until just combined for a tender texture.
- Even out each layer: Smooth each layer so they bake uniformly.
- Use parchment for clean removal: It helps lift the entire slab out for easier slicing.
- Chill before slicing: This makes cleaner cuts and keeps the layers intact.
- Customize the recipe: Add peanut butter chips, caramel drizzle, or swap in flavored cookies.
