Raspberry Swirl Brownies (Print Version)

Fudgy chocolate brownies with tangy raspberry swirl for a perfect sweet-tart balance.

# What You Need:

→ Raspberry Swirl

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

→ Brownie Base

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

# Directions:

01 - Preheat oven to 350°F. Line an 8-inch square baking pan with parchment paper, allowing 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 - Place butter and chopped chocolate in a heatproof bowl set over a pan of simmering water. Stir until completely melted and smooth. Remove from heat and let cool slightly.
04 - Whisk sugar into the chocolate mixture, then add eggs one at a time, mixing thoroughly after each addition. Stir in vanilla extract.
05 - Sift flour, cocoa powder, and salt into the bowl. Gently fold until just combined—do not overmix.
06 - Pour batter into prepared pan and smooth top. Drop spoonfuls of raspberry puree over batter, then use a knife or skewer to swirl, creating a marbled pattern.
07 - Bake for 30-35 minutes until a toothpick inserted in center comes out with a few moist crumbs. Cool completely in pan before lifting out and cutting into squares.

# Expert Tips:

01 -
  • The raspberry cuts through the rich chocolate like a bright tangy secret
  • Fudgy centers with slightly crisp edges make every bite interesting
  • They look stunning but the marble technique is forgiving and fun
02 -
  • Overmixing the flour is the quickest way to turn fudgy brownies into cakey ones
  • The raspberry swirl sinks if you add it while the puree is still hot
  • These continue to firm up as they cool so do not overbake
03 -
  • Room temperature ingredients prevent the melted chocolate from seizing
  • A slightly underbaked brownie firms up perfectly as it cools
