Ingredients

Scale

Brownie Batter

  • 1/2 cup butter
  • 1 1/2 cups semi-sweet chocolate chips (225 grams)
  • 3 eggs
  • 1 cup granulated sugar
  • 1 teaspoon vanilla extract
  • 1/2 cup all-purpose flour
  • 1/2 teaspoon salt
  • 1/8 teaspoon baking soda
  • 1/8 teaspoon baking powder

Raspberry Sauce

  • 1/2 cup raspberries, fresh or frozen
  • 1/2 cup sugar
  • A small amount of water (about 1-2 tablespoons)

Instructions

  1. Prepare the Baking Pan: Line an 8-inch baking pan with parchment paper or foil, ensuring there is some overhang for easy removal. Lightly coat the lining with cooking spray to prevent sticking.
  2. Make the Raspberry Sauce: In a saucepan, combine the raspberries, sugar, and a small splash of water. Heat over medium heat, stirring until the sugar dissolves and the mixture turns saucy. Mash the raspberries with a spoon or use an immersion blender for a smoother texture. Bring the sauce to a boil for a few minutes, then remove from heat. Strain the mixture through a fine sieve to remove the seeds and set aside the smooth sauce.
  3. Preheat the Oven: Preheat your oven to 350°F (175°C) so it will be ready once the batter is prepared.
  4. Prepare the Chocolate Mixture: In a larger saucepan, melt the butter and semi-sweet chocolate chips together over low heat until silky smooth. Turn off the heat and allow it to cool; you can place it in the fridge briefly to speed up the process.
  5. Mix Ingredients: In a separate bowl, whisk the eggs with the granulated sugar and vanilla extract until well combined. Slowly add this egg mixture to the cooled chocolate mixture, stirring continuously to temper the eggs and avoid scrambling.
  6. Finalize and Bake the Brownie Batter: Add the flour, salt, baking powder, and baking soda to the chocolate and egg mixture. Stir until fully incorporated and the batter is smooth. Pour the batter evenly into the prepared baking pan. Spoon small amounts of the prepared raspberry sauce over the batter, then use a knife to gently swirl the sauce into the top layer to create a marbled effect.
  7. Bake the Brownies: Bake in the preheated oven for 30 minutes, or until a toothpick inserted into the center comes out with just a few moist crumbs. Allow the brownies to cool completely in the pan before lifting them out by the parchment or foil overhang. Slice and serve.

Notes

  • For a smoother raspberry swirl, blend the raspberry sauce thoroughly before swirling.
  • Make sure the chocolate mixture is cooled before adding the eggs to prevent scrambling.
  • Use fresh raspberries if possible for the best flavor, but frozen works well too.
  • Brownies continue to set as they cool, so avoid overbaking for fudgy texture.
  • If desired, dust the finished brownies lightly with powdered sugar before serving.
