Ingredients
  

  • 1 cup unsalted butter melted and slightly cooled (2 sticks / 226 g)
  • 1 3/4 cups granulated sugar about 350 g
  • 1/4 cup light brown sugar packed, about 50 g
  • 3 large eggs at room temperature
  • 1 large egg yolk at room temperature
  • 2 teaspoons pure vanilla extract
  • 2 tablespoons unsweetened cocoa powder natural or Dutch-process
  • 1 tablespoon red food coloring liquid; or 2–3 teaspoons gel, adjusted to taste
  • 1 teaspoon distilled white vinegar
  • 1/2 teaspoon fine sea salt or 3/4 teaspoon kosher salt
  • 1 1/3 cups all-purpose flour about 170 g, spooned and leveled
  • 1/2 cup mini semi-sweet chocolate chips plus extra for sprinkling on top, optional (about 85 g)
  • 4 ounces cream cheese softened; full-fat block, about 113 g
  • 2 tablespoons unsalted butter softened, for frosting
  • 1 cup powdered sugar sifted, about 120 g
  • 1/2 teaspoon pure vanilla extract for frosting
  • 1 tablespoon milk or heavy cream up to 2 tablespoons, as needed for consistency
  • nonstick spray for greasing the pan
  • parchment paper to line the baking pan

Instructions
 

  • Preheat your oven to 350°F (177°C). Line a 9×13-inch baking pan with parchment paper, leaving an overhang on the long sides to lift the bars out later. Lightly spray the parchment and any exposed sides of the pan with nonstick spray.

  • In a large microwave-safe bowl, melt the butter in 20–30 second bursts until just melted. Let it cool for about 5 minutes, until warm but not hot.
    1 cup unsalted butter
  • Add the granulated sugar and brown sugar to the warm butter and whisk until smooth and glossy. Add the eggs, egg yolk, and vanilla, whisking well after each addition until the mixture is thick and shiny.
    1 3/4 cups granulated sugar, 1/4 cup light brown sugar, 3 large eggs, 1 large egg yolk, 2 teaspoons pure vanilla extract
  • Whisk in the cocoa powder, red food coloring, vinegar, and salt until fully combined and evenly colored. If the batter looks too pale, add a bit more food coloring to taste.
    2 tablespoons unsweetened cocoa powder, 1 tablespoon red food coloring, 1 teaspoon distilled white vinegar, 1/2 teaspoon fine sea salt
  • Sprinkle the flour over the wet mixture and gently fold it in with a spatula just until no dry streaks remain. Fold in the mini chocolate chips, being careful not to overmix.
    1 1/3 cups all-purpose flour, 1/2 cup mini semi-sweet chocolate chips
  • Pour the thick batter into the prepared pan. Smooth the top with an offset spatula or the back of a spoon, nudging it into the corners. If desired, sprinkle extra chocolate chips over the top.

  • Bake on the center rack for 24–30 minutes, starting to check around 22–23 minutes. The edges should look set and start to pull slightly from the sides, while the center should be puffed and just barely glossy. A toothpick inserted about 2 inches from the edge should come out with a few moist crumbs, not wet batter.
  • Set the pan on a wire rack and let the brownies cool completely in the pan, about 1 hour. Do not cut while warm, as the texture finishes setting as they cool.
  • In a medium bowl, beat the softened cream cheese and softened butter together until smooth and creamy. Add the powdered sugar and vanilla and beat until thick and fluffy. If the frosting is too stiff, add milk or cream 1 teaspoon at a time until it is easily spreadable.

  • Once the bars are completely cool, spread the cream cheese frosting over the top in an even layer. For the neatest slices, chill the frosted pan in the refrigerator for 30–45 minutes before cutting.

  • Use the parchment overhang to lift the slab out of the pan and transfer to a cutting board. Cut into 16 large or up to 24 smaller bars, wiping the knife clean between cuts for sharp edges.

Notes

Don’t overbake—pull the bars when the edges are set and the center is just slightly glossy, as they continue to set while cooling. Use room temperature eggs to prevent the melted butter from seizing. For extra-clean slices, cut with a hot, wiped-dry knife. The flavor improves after resting overnight, and the recipe is designed for a 9×13-inch pan for ideal thickness and texture.
