Equipment

  • 8×8-inch baking pan
  • parchment paper
  • Mixing bowls
  • Whisk
  • electric mixer (optional)
  • knife for swirling

Ingredients
  

  • 1/4 cup sourdough discard
  • 1/2 cup unsalted butter, melted
  • 1 cup granulated sugar
  • 2 large eggs
  • 1/2 teaspoon salt
  • 1/2 teaspoon vanilla extract
  • 2/3 cup cocoa powder
  • 1/2 cup all-purpose flour
  • 1/4 cup chocolate chips (milk, dark, or white)
  • 8 oz cream cheese, softened
  • 1/4 cup granulated sugar
  • 1 large egg
  • 1/2 teaspoon vanilla extract
  • 1/2 teaspoon salt

Instructions
 

  • Preheat the oven to 350°F (175°C). Line an 8×8-inch baking pan with parchment paper and lightly grease.
  • In a large bowl, whisk together sourdough discard, melted butter, sugar, eggs, cocoa powder, flour, salt, and vanilla until smooth.
  • Spread half of the brownie batter evenly into the prepared pan.
  • Sprinkle the chocolate chips evenly over the batter.
  • In a separate bowl, beat cream cheese, sugar, egg, vanilla, and salt until creamy and lump-free.
  • Spoon cheesecake mixture over the brownie layer. Add remaining brownie batter in dollops and swirl gently with a knife for a marbled effect.
  • Bake for 37–40 minutes, until the center is set with a few moist crumbs on a toothpick.
  • Let brownies cool completely, then refrigerate before slicing for clean edges and best texture.

Notes

Chill thoroughly for the cleanest slices. Use room-temperature cream cheese for a smooth swirl. Avoid overbaking to keep the brownies fudgy. Use high-quality cocoa powder for best results. Brownies taste even better the next day as flavors deepen.
