Ingredients

Scale

Brownie Batter:

  • 1 1/2 cups semi-sweet chocolate chips (good quality)
  • 1 tsp vanilla extract
  • 1/2 cup unsalted butter (preferably Kerrygold)
  • 1/8 tsp baking soda
  • 1/8 tsp baking powder
  • 1/2 cup all-purpose flour
  • 3 eggs (room temperature)
  • 1/2 tsp fine sea salt
  • 1 cup granulated sugar

Raspberry Swirl:

  • 1/2 cup granulated sugar
  • Small splash of water
  • 1/2 cup raspberries

Instructions

  1. Prepare the Baking Pan: Line an 8-inch baking pan with parchment paper or foil, leaving an overhang for easy removal. Lightly coat with cooking spray to prevent sticking.
  2. Make the Raspberry Sauce: In a saucepan, combine raspberries, sugar, and a splash of water. Stir over medium heat until sugar dissolves and mixture becomes saucy. Mash with a spoon or blend for smoother texture. Boil for a few minutes, then remove from heat. Strain to remove seeds and set aside.
  3. Preheat the Oven: Set your oven to 350°F (175°C) so it’s ready when batter preparation is complete.
  4. Prepare the Chocolate Mixture: Melt butter and chocolate chips together in a large saucepan over low heat until silky smooth. Turn off heat and let cool, refrigerating briefly if needed to speed cooling.
  5. Mix Ingredients: In a bowl, whisk eggs, sugar, and vanilla until well combined. Gradually add this to the cooled chocolate mixture, stirring continuously to temper eggs and avoid scrambling.
  6. Finalize and Bake the Brownie Batter: Stir in flour, salt, baking powder, and baking soda until smooth. Pour batter evenly into prepared pan. Spoon raspberry sauce over batter and swirl gently with a knife to create a marbled effect.
  7. Bake the Brownies: Bake for 30 minutes or until a toothpick inserted in the center comes out with moist crumbs. Allow brownies to cool completely in the pan before lifting out with parchment overhang, slicing, and serving.

Notes

  • Ensure eggs are at room temperature for better emulsion and texture.
  • Use high-quality semi-sweet chocolate chips for richer flavor and smoother melting.
  • Swirling the raspberry sauce gently avoids mixing it completely into the batter, maintaining a beautiful marbled appearance.
  • Cooling the brownies fully before slicing helps them set and makes cutting cleaner.
  • Straining the raspberry sauce removes seeds for a smoother swirl texture.
