Raspberry Swirl Brownies (Printer-friendly)

Fudgy chocolate brownies with a vibrant raspberry swirl, balancing rich cocoa and bright fruit flavors.

# 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 Make It:

01 - Preheat 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 - 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—be careful not to 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, 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 using the parchment overhang and cut into squares.

# Expert Tips:

01 -
  • The tangy raspberry cuts through rich chocolate like a bright note in a dark song
  • They look impressively fancy but come together in under an hour
02 -
  • Over-swirling the raspberry makes muddy-looking brownies, so make just 3 or 4 passes through the batter
  • The toothpick test is tricky here, check the center not the raspberry swirls for accuracy
03 -
  • Add a handful of dark chocolate chips to the batter for pockets of extra richness
  • Chill the raspberry puree before swirling so it holds its shape better
