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 (approximately 1-2 tablespoons)

Instructions

  1. Prepare the Baking Pan: Line an 8-inch baking pan with parchment paper or foil, leaving overhang on the sides for easy removal later. Lightly coat the lining with cooking spray to prevent sticking during baking.
  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 using a spoon or blend with an immersion blender for a smooth consistency. Bring the sauce to a boil for a few minutes, then remove from heat. Strain the sauce to remove seeds and set aside.
  3. Preheat the Oven: Preheat your oven to 350°F (175°C) so it is ready when the batter preparation is complete.
  4. Prepare the Chocolate Mixture: In a larger saucepan, melt the butter and semi-sweet chocolate chips over low heat, stirring continuously until smooth and silky. Remove from heat and allow to cool. To expedite cooling, you can place the saucepan in the refrigerator.
  5. Mix Ingredients: In a separate bowl, whisk together eggs, granulated sugar, and vanilla extract until well combined. Slowly add this egg mixture to the cooled chocolate mixture while stirring continuously to temper the eggs and prevent curdling.
  6. Finalize and Bake the Brownie Batter: Add the all-purpose flour, salt, baking powder, and baking soda to the chocolate and egg mixture. Stir until fully combined and a smooth batter forms. Pour the batter evenly into the prepared baking dish. Spoon small amounts of raspberry sauce over the batter and use a knife to swirl the sauce gently into the top layer, creating a marbled effect.
  7. Bake the Brownies: Place the baking dish in the preheated oven and bake for approximately 30 minutes. Check doneness by inserting a toothpick into the center; it should come out with a few moist crumbs but not wet batter. Remove from oven and allow to cool before slicing and serving.

Notes

  • Use fresh or frozen raspberries for the sauce; if using frozen, thaw slightly before cooking.
  • For a smoother raspberry sauce, use an immersion blender and strain to remove seeds completely.
  • Cooling the chocolate mixture before adding eggs is essential to prevent scrambled eggs.
  • Swirling the raspberry sauce gently avoids mixing it completely into the batter and preserves the marbled appearance.
  • Store brownies in an airtight container at room temperature for up to 3 days or refrigerate for longer freshness.
