Ingredients
Method
- **Heat.** Preheat oven to 350F. Line a 9x13 inch pan with parchment paper, leaving overhang on two sides.
- **Brownies.** Melt 10 tbsp butter in a saucepan. Whisk in granulated sugar, cocoa, salt, and vanilla. Add eggs one at a time, then flour. Spread evenly in the pan.
- **Cookies.** In a separate bowl beat softened butter, brown sugar, and granulated sugar 2 minutes until fluffy. Add egg and vanilla. Mix in flour, baking soda, salt, and chocolate chips. Chill 30 minutes.
- **Top.** Scoop chilled cookie dough by golf ball sized lumps over the brownie layer. Press gently to flatten slightly without merging into the brownie.
- **Bake.** Bake 28 to 32 minutes until cookie tops are set and golden, brownie has moist crumbs.
- **Cool.** Cool in pan 1 hour before lifting out by parchment.
- **Slice.** Cut into 12 thick bars and serve.
Notes
Chill cookie dough 30 minutes before scooping onto the brownie layer. Use Dutch process cocoa for the deepest brownie color and flavor. Score the bars hot but cool completely before slicing for clean cuts.
