Raspberry Swirl Brownies (Printable)

Fudgy chocolate brownies marbled 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 Make It:

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 small saucepan. Cook over medium heat, stirring occasionally, until raspberries break down and mixture thickens, about 5 minutes. Press through fine-mesh sieve to remove seeds. Set aside to cool.
03 - Set heatproof bowl over pan of simmering water. Melt butter and chocolate together, stirring until smooth. Remove from heat and cool slightly.
04 - Whisk sugar into 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. Avoid overmixing.
06 - Pour batter into prepared pan and smooth top. Drop spoonfuls of raspberry puree over batter. Use knife or skewer to gently swirl raspberry into brownie mix, creating marbled pattern.
07 - Bake for 30-35 minutes until toothpick inserted in center comes out with few moist crumbs.
08 - Cool completely in pan. Lift out using parchment overhang and cut into squares.

# Expert Advice:

01 -
  • The tart raspberry cuts through rich chocolate like a bright note in a deep song
  • These brownies manage to feel fancy enough for company but simple enough for a Tuesday night craving
02 -
  • Letting both the raspberry puree and melted chocolate cool slightly before combining prevents the swirl from sinking to the bottom
  • Over swirling mixes the raspberry too thoroughly into the chocolate, losing that beautiful marbled effect
03 -
  • Room temperature ingredients prevent the melted chocolate from seizing when you add the eggs
  • A light dusting of powdered sugar over the cooled brownies makes them look professionally finished
