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 amount of water (just enough to dissolve sugar, about 1-2 tbsp)
  • 1/2 cup raspberries (fresh or thawed frozen)

Instructions

  1. Prepare the Baking Pan: Line an 8-inch baking pan with parchment paper or foil, leaving an overhang on the sides for easy removal. Lightly coat the lining with cooking spray to ensure the brownies don’t stick.
  2. Make the Raspberry Sauce: In a small saucepan, combine the raspberries, 1/2 cup sugar, and a splash of water. Heat over medium heat, stirring frequently, until the sugar dissolves and the mixture thickens slightly. Mash the raspberries with a spoon or blend with an immersion blender for a smoother consistency. Bring the sauce to a brief boil for a few minutes, remove from heat, strain through a fine sieve to remove seeds, and set aside to cool.
  3. Preheat the Oven: Set your oven to 350°F (175°C) so it reaches the right temperature while you prepare the batter.
  4. Prepare the Chocolate Mixture: In a larger saucepan, melt the butter and semi-sweet chocolate chips together over low heat, stirring gently until smooth and fully combined. Remove from heat and allow to cool to prevent scrambling the eggs.
  5. Mix Ingredients: Whisk the eggs, granulated sugar, and vanilla extract in a separate bowl until thoroughly combined. Gradually add this egg mixture to the cooled chocolate-butter mixture, stirring continuously to temper the eggs and achieve a smooth blend.
  6. Finalize and Bake the Brownie Batter: Add the flour, salt, baking powder, and baking soda to the chocolate-egg mixture. Stir gently until the batter is smooth and homogeneous. Pour the batter evenly into the prepared pan. Spoon small dollops of the raspberry sauce over the top and use a knife or skewer to swirl it into the batter, creating an attractive marbled effect.
  7. Bake the Brownies: Place the pan in the preheated oven and bake for 30 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs, indicating fudgy doneness.
  8. Cool and Serve: Allow the brownies to cool completely in the pan. Use the parchment or foil overhang to lift the brownies out easily, then slice and serve to enjoy the harmonious blend of chocolate and raspberry flavors.

Notes

  • Room temperature eggs help achieve a smoother, more stable batter.
  • Using high-quality semi-sweet chocolate chips improves the flavor and texture of the brownies.
  • The raspberry swirl can be adjusted for sweetness by adding more or less sugar, depending on your taste and raspberry tartness.
  • For a gluten-free version, substitute all-purpose flour with a gluten-free baking blend of equal quantity.
  • Ensure the chocolate mixture has cooled sufficiently before adding eggs to prevent curdling.
  • Storing brownies in an airtight container at room temperature maintains moisture for up to 3 days.
