Step-by-Step Instructions
- Preheat your oven to 350°F (175°C) and line a 9x13 inch baking pan with parchment paper.
- Melt the unsalted butter in a microwave-safe bowl. Whisk in the granulated sugar until smooth, then add cocoa powder, vanilla extract, gel food coloring, white vinegar, eggs, flour, and salt. Mix until just combined.
- Cream together softened unsalted butter with packed brown sugar and granulated sugar until light and fluffy. Beat in the egg and vanilla extract, then add flour, baking soda, and salt. Fold in chocolate chips.
- Drop alternating spoonfuls of the brownie batter and cookie dough into the pan, creating a checkerboard pattern. Optionally swirl with a toothpick.
- Bake for 22 to 28 minutes until set yet slightly underbaked in the center. A toothpick should come out with a few moist crumbs.
- Remove from oven, sprinkle flaky sea salt on top while warm, and cool in the pan for at least 2 hours before cutting.

Notes
Use high-quality cocoa powder and pure vanilla extract for the best flavor. Allow brookies to cool completely before cutting for the best texture.
