Ingredients

Scale
  • 1 cup (2 sticks) unsalted butter, melted
  • 2 cups granulated sugar
  • 4 large eggs
  • 1 teaspoon vanilla extract
  • 3/4 cup unsweetened cocoa powder
  • 1 cup all-purpose flour
  • 1/2 teaspoon salt
  • 1 cup fresh strawberries, finely chopped
  • 1/4 cup powdered sugar (for strawberry layer)
  • 1 tablespoon lemon juice (for strawberry layer)
  • 1/2 cup fresh strawberries, pureed (for swirl)
  • Optional Glaze: 1 cup powdered sugar, 2 tablespoons milk, 1/2 teaspoon strawberry extract

Instructions

  1. Preheat your oven to 350°F (175°C). Line a 9×9 inch baking pan with parchment paper, leaving an overhang for easy removal.
  2. In a large bowl, whisk together the melted butter and granulated sugar until combined.
  3. Beat in the eggs one at a time, mixing well after each addition. Stir in the vanilla extract.
  4. In a separate bowl, whisk together the cocoa powder, flour, and salt. Gradually add the dry ingredients to the wet ingredients, mixing until just combined. Do not overmix.
  5. Gently fold in the finely chopped fresh strawberries.
  6. In a small bowl, mix the strawberry puree with 1/4 cup powdered sugar and lemon juice to create a thick strawberry mixture.
  7. Spread half of the brownie batter into the prepared pan. Dollop spoonfuls of the strawberry mixture over the batter. Top with the remaining brownie batter.
  8. Use a knife or skewer to gently swirl the strawberry mixture through the batter to create a marble effect.
  9. Bake for 30 to 35 minutes, or until a toothpick inserted near the center comes out with moist crumbs attached, not wet batter. This ensures a fudgy texture.
  10. Let the brownies cool completely in the pan on a wire rack.
  11. If using the glaze, whisk together powdered sugar, milk, and strawberry extract until smooth. Drizzle over the cooled brownies before cutting.
  12. Lift the brownies out using the parchment paper overhang and cut into squares.

Notes

  • For the fudgiest texture, avoid overbaking. The center should still look slightly underdone when you remove them from the oven.
  • If you prefer a cake-like texture, add 1/4 teaspoon of baking powder to the dry ingredients.
  • You can substitute fresh strawberries with 1/2 cup of good quality strawberry jam swirled into the batter if fresh berries are unavailable.
