Raspberry Swirl Brownies (Printable)

Fudgy chocolate brownies with tangy raspberry swirl 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 the 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, approximately 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. 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—take care not to overmix.
06 - Pour brownie batter into the prepared pan and smooth the surface. 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 30–35 minutes, 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 tart raspberry cuts through the rich chocolate like a bright surprise in every bite
  • These look like they came from a fancy bakery but take less than an hour to make
  • The marbled pattern makes each brownie unique and gorgeous
02 -
  • Let the raspberry puree cool completely before swirling so it does not sink into the batter
  • Underbaking slightly is better than overbaking, these continue cooking as they cool
  • The parchment overhang is your best friend for lifting the whole batch out cleanly
03 -
  • The puree can be made a day ahead and kept refrigerated until you are ready to bake
  • Use the lightest colored pan you have or the edges might overcook before the center sets
