Method
Preparation
- Preheat your oven to 350°F (175°C) and grease a 9x9-inch pan, or line it with parchment paper leaving an overhang for easy removal.
- In a medium bowl, whisk together flour, cocoa powder, baking powder, and salt until evenly combined.
- In another bowl, whisk melted butter with granulated sugar until smooth. Add the eggs one at a time, whisking after each, then stir in vanilla extract.
- Add the dry ingredients to the wet mixture and fold just until no streaks of flour remain. Fold in chocolate chips.
Layering
- Spread half of the brownie batter evenly into the prepared pan. Dot the surface with tablespoon-sized pieces of cookie dough, covering most of the surface but leaving small gaps.
- Spoon or dollop the remaining brownie batter over the cookie dough and gently spread to cover.
Baking
- Bake for 25-30 minutes, testing doneness by looking for a slightly puffed surface and a toothpick that comes out with a few moist crumbs.
- Remove and cool on a wire rack for 20-30 minutes before lifting the slab out using the parchment overhang. Cut into squares once fully cooled.
Notes
For best results, avoid overbaking and overmixing. Allow to cool completely before cutting to ensure clean edges.
