Ingredients

The following ingredients have 4 Servings
  • 10 tablespoons unsalted butter
  • 1 1/4 cup white sugar
  • 2 tablespoons cocoa powder
  • 1 large egg
  • 1 large egg yolk* (discard the egg white)
  • 1 teaspoon vanilla extract
  • 1 1/2 tablespoon red food coloring
  • 1 1/4 cup all-purpose flour
  • 1/4 teaspoon salt
  • 1 teaspoon white vinegar
  • 1 cup white chocolate chips

Instruction

  • Preheat the oven to 350F degrees and position the oven rack in the middle of your oven.
  • Line an 8x8 inch (20x20 cm) metal baking pan with parchment paper, or line with aluminum foil and lightly grease.
  • Add the butter to a large bowl and microwave for 45-second intervals until melted.
  • Whisk in the sugar and cocoa powder. Whisk vigorously for 20-30 seconds.
  • Whisk in the egg, extra egg yolk, vanilla extract and red food coloring.
  • Carefully fold in the flour and salt using a rubber spatula or wooden spoon.
  • Whisk in the vinegar.
  • Stir in the chocolate chips.
  • Pour the batter into the prepared pan and bake for 28-32 minutes, or until an inserted toothpick comes out clean or with a few damp crumbs.
  • Cool the brownies in the pan for at least 4 hours, or until completely cooled before slicing. To slice, lift the bars out of the pan using the overhang of the parchment paper/aluminum foil. Then cut with a sharp knife of a cutting board.
