Raspberry Swirl Brownies (Printable)

Rich chocolate brownies swirled with tangy raspberry puree for a perfect sweet-tart balance.

# What You’ll Need:

→ Raspberry Swirl

01 - 1 cup fresh or frozen raspberries
02 - 2 tablespoons granulated sugar
03 - 1 teaspoon fresh lemon juice

→ Brownies

04 - 1/2 cup unsalted butter
05 - 4 oz bittersweet chocolate, chopped
06 - 1 cup granulated sugar
07 - 2 large eggs
08 - 1 teaspoon pure vanilla extract
09 - 1/2 cup all-purpose flour
10 - 1/4 cup unsweetened cocoa powder
11 - 1/4 teaspoon salt

# How-To Steps:

01 - Preheat the oven to 350°F. Line an 8-inch square baking pan with parchment paper, leaving overhang for easy removal.
02 - Combine raspberries, sugar, and lemon juice in a small saucepan. Cook over medium heat, stirring occasionally, until raspberries break down and mixture thickens, about 5 minutes. Press through a fine-mesh sieve to remove seeds. Set aside to cool.
03 - Set a heatproof bowl over a pan of simmering water. Melt butter and chocolate together, stirring until smooth. Remove from heat and cool slightly.
04 - Whisk sugar into the chocolate mixture. Add eggs one at a time, mixing well after each addition. Stir in vanilla extract.
05 - Sift in flour, cocoa powder, and salt. Gently fold until just combined—do not overmix.
06 - Pour brownie batter into the prepared pan and smooth the top. Drop spoonfuls of raspberry puree over the batter. Use a knife or skewer to gently swirl the raspberry into the brownie mix, creating a marbled pattern.
07 - Bake for 30 to 35 minutes, or until a toothpick inserted in the center comes out with a few moist crumbs.
08 - Cool completely in the pan, then lift out and cut into squares.

# Expert Tips:

01 -
  • The tart raspberry cuts through the intense chocolate like a bright surprise
  • These look impressive but come together in under an hour
  • The marble pattern makes every slice feel like a little work of art
02 -
  • Overmixing the flour turns these into cake instead of fudgy brownies
  • The raspberry puree must cool before swirling or it will sink to the bottom
  • Letting them cool completely is the hardest part but makes cutting so much easier
03 -
  • Chill the swirl puree in the fridge for 10 minutes if it feels too runny
  • Run your knife under hot water between swirls for cleaner lines
