Ingredients:

  • 1 cup (226g) unsalted butter
  • 2 cups (400g) granulated sugar
  • 4 large eggs
  • 1 tablespoon vanilla extract
  • 1 cup (125g) all-purpose flour
  • ½ cup (50g) unsweetened cocoa powder
  • ½ teaspoon salt
  • 1 teaspoon baking powder
  • Red food coloring (about 3 tablespoons or to desired color)
  • 8 oz (226g) cream cheese, softened
  • ½ cup (60g) powdered sugar
  • 1 egg yolk
  • 1 teaspoon vanilla extract

Instructions:

  1. Preheat your oven to 350°F (175°C). Grease a 9x13 inch baking pan or line it with parchment paper for easy removal.
  2. In a medium saucepan, melt the butter over low heat. Remove from heat and stir in granulated sugar until combined.
  3. Add eggs one at a time, mixing well after each addition. Stir in vanilla extract.
  4. In a separate bowl, whisk together flour, cocoa powder, salt, and baking powder.
  5. Gradually add dry ingredients to wet mixture until just combined. Mix in red food coloring until you achieve your desired shade of crimson.
  6. In a mixing bowl, beat softened cream cheese with powdered sugar until smooth. Add egg yolk and vanilla extract; mix until fully incorporated.
  7. Pour half of the brownie batter into the prepared pan and spread evenly. Dollop spoonfuls of cream cheese mixture over brownie batter. Use a knife to gently swirl it through the batter without fully combining it.
  8. Pour remaining brownie batter on top and repeat dolloping with leftover cream cheese mixture; swirl again.
  9. Bake in preheated oven for about 30–35 minutes, or until edges are set but center is slightly soft when tested with a toothpick.
  10. Allow brownies to cool completely in pan on wire rack before cutting into squares.
