Best Raspberry Swirl Brownies

Raspberry swirl brownies are a delightful twist on the classic chocolate brownie. The rich, fudgy texture of the brownie is complemented by the vibrant, slightly tart raspberry swirl, creating the perfect balance of sweetness and fruitiness. These brownies are an ideal dessert for any occasion, from casual family dinners to special gatherings. The combination of smooth chocolate and fresh raspberries is sure to impress anyone who takes a bite.

Equipment

  • 8x8-inch baking pan: A square baking pan is perfect for this recipe and helps achieve even cooking.
  • Medium saucepan: For making the raspberry sauce.
  • Hand mixer or whisk: To mix the brownie batter.
  • Spatula: To smooth the brownie batter and swirl the raspberry sauce.
  • Knife or skewer: For creating the swirl in the brownies.

Ingredients

  • For the Brownie Base:
  • 1/2 cup unsalted butter melted
  • 1 cup granulated sugar
  • 2 large eggs
  • 1 tsp vanilla extract
  • 1/3 cup unsweetened cocoa powder
  • 1/2 cup all-purpose flour
  • 1/4 tsp salt
  • 1/4 tsp baking powder
  • 1/2 cup semi-sweet chocolate chips optional, for extra fudginess
  • For the Raspberry Swirl:
  • 1 cup fresh or frozen raspberries
  • 1/4 cup granulated sugar
  • 1 tbsp water
  • 1 tsp lemon juice

Instructions

  • Step 1: Make the Raspberry Sauce
  • In a medium saucepan, combine the raspberries, sugar, water, and lemon juice.
  • Heat the mixture over medium heat, stirring occasionally, until the raspberries break down and the sauce thickens (about 5-7 minutes).
  • Remove the sauce from the heat and let it cool slightly. Once cooled, use a spoon or a whisk to break up any remaining chunks of raspberry. You should have about 1/4 to 1/3 cup of raspberry sauce. Set aside.
  • Step 2: Prepare the Brownie Batter
  • Preheat your oven to 350°F (175°C). Grease and line an 8x8-inch baking pan with parchment paper.
  • In a large mixing bowl, whisk together the melted butter and sugar until well combined.
  • Add the eggs and vanilla extract, mixing until smooth.
  • Sift in the cocoa powder, flour, salt, and baking powder. Stir until fully combined. If you’re using chocolate chips, fold them in at this stage.
  • Pour the brownie batter into the prepared pan, spreading it evenly.
  • Step 3: Add the Raspberry Swirl
  • Using a spoon, drop spoonfuls of the raspberry sauce on top of the brownie batter.
  • Using a knife or skewer, gently swirl the raspberry sauce into the brownie batter to create a marbled effect. Don’t over-mix; you want to create beautiful swirls of raspberry in each bite.
  • Bake for 25-30 minutes, or until a toothpick inserted into the center comes out mostly clean with a few moist crumbs. The top should look set but slightly cracked.
  • Step 4: Cool and Serve
  • Allow the brownies to cool in the pan for about 10 minutes before transferring them to a wire rack to cool completely.
  • Once cooled, cut the brownies into squares and serve. You can add a dollop of whipped cream or a scoop of vanilla ice cream for an extra treat!
