Step-by-Step Instructions
Prepare the Brownie Layer:
Step 1: Preheat and Prep Preheat oven to 350°F and line an 8×8 inch square baking pan with parchment paper, leaving overhang for easy removal.
Step 2: Melt Chocolate and Butter In a double boiler or microwave-safe bowl, melt butter and chopped chocolate together until smooth. Let cool slightly.
Step 3: Mix Brownie Batter Stir sugar into the chocolate mixture until combined. Beat in eggs one at a time, then vanilla. Fold in flour, cocoa powder, and salt just until combined—don’t overmix.
Step 4: Create the Base Spread brownie batter evenly in the prepared pan, smoothing the top with a spatula.
Make the Cookie Layer:
Step 5: Cream Butter and Sugars In a separate bowl, cream together softened butter, brown sugar, and granulated sugar until light and fluffy, about 3 minutes.
Step 6: Add Wet Ingredients Beat in egg and vanilla extract until well combined.
Step 7: Mix Dry Ingredients In another bowl, whisk together flour, baking soda, and salt. Gradually mix dry ingredients into butter mixture until just combined.
Step 8: Fold in Chocolate Chips Gently fold chocolate chips into cookie dough until evenly distributed.
Assemble and Bake:
Step 9: Layer the Cookie Dough Drop spoonfuls of cookie dough over the brownie batter, then gently spread to cover most of the surface, leaving some brownie visible for visual interest.
Step 10: Bake to Perfection Bake for 35-40 minutes until the cookie layer is golden brown and set, and a toothpick inserted in brownie layer comes out with a few moist crumbs.
Cool and Serve:
Step 11: Cool Completely Let cool completely in the pan before lifting out using parchment overhang. This ensures clean cuts and proper texture.
Step 12: Cut and Enjoy Cut into squares using a sharp knife, wiping between cuts for the cleanest presentation.

Chocolate Chip Cookie Brownies FAQs
How do I prevent the layers from mixing during baking? Make sure the brownie layer is spread evenly and set slightly before adding cookie dough. Drop cookie dough gently and spread carefully.
Can I use box mix for either layer? You can, though homemade provides better texture and flavor control. If using mixes, choose high-quality brands and follow package directions.
Why are my brownies too dry or too gooey? Overbaking creates dryness, while underbaking leaves them too gooey. Look for set cookie layer and moist brownie crumbs on a toothpick.
Can I make these in a different pan size? A 9×9 pan works but will be slightly thinner. Adjust baking time accordingly and watch for doneness cues.
How do I get clean cuts? Use a sharp knife, wipe between cuts, and make sure they’re completely cool before cutting for the neatest presentation.
