Method
Preparation
- Preheat the oven to 350°F (175°C) and line a baking sheet with parchment paper.
- In a large bowl, melt the butter. Stir in brown sugar and granulated sugar until the mixture is glossy and thick.
- Mix in eggs and vanilla until the batter is smooth and cohesive.
- In a separate bowl, whisk together flour, baking soda, and salt.
Combining Ingredients
- Gradually stir the dry ingredients into the wet mixture until just combined. Fold in chocolate chips.
Making the Brownie Filling
- In a separate bowl, mix brownie mix with water until smooth and thick.
Assembling the Cookies
- Scoop a portion of cookie dough, press a well into it, spoon brownie mixture into the center, and wrap the dough around it.
- Place the dough balls on the baking sheet about 2 inches apart.
Baking
- Bake for 10–12 minutes, until edges are golden but centers look soft.
- Let cool on the baking sheet for a few minutes, then transfer to a wire rack.
Notes
For the chewiest texture, remove cookies while centers look soft. Store brookie cookies in an airtight container at room temperature, or freeze for longer storage.
