Ingredients
Brownie Batter
- 2 ounces dark chocolate (52% cocoa)
- 2 ounces white chocolate
- ½ cup butter, softened
- ⅔ cup granulated sugar
- 2 large eggs, room temperature
- ½ teaspoon vanilla extract
- ½ cup all-purpose flour
- 1 pinch salt (if using unsalted butter, add ¼ teaspoon salt)
Instructions
- Preheat and Prepare Pan: Preheat your oven to 350°F (180°C). Grease and flour an 8-inch square baking pan, or alternatively spray or line it with parchment paper to prevent sticking.
- Melt Chocolates: Melt the dark and white chocolate separately, then set them aside to cool until lukewarm to avoid cooking the batter when combined.
- Cream Butter and Sugar: In a mixing bowl, cream the softened butter and granulated sugar together until fluffy, about 2-3 minutes. This incorporates air for a lighter texture.
- Add Eggs and Vanilla: Beat in the eggs one at a time, ensuring each is fully incorporated before adding the next. Stir in the vanilla extract for added flavor.
- Combine Dry Ingredients: Gently fold in the all-purpose flour and salt using a wooden spoon or spatula until just combined, careful not to overmix to keep the brownies tender.
- Divide and Mix Chocolate Batter: Transfer half of the batter into a clean bowl and stir in the melted dark chocolate. In the original bowl, stir in the melted white chocolate with the remaining batter.
- Layer and Swirl Batter: Spread the dark chocolate batter evenly on the bottom of the prepared pan. Drop spoonfuls of the white chocolate batter on top and gently spread it. Then spoon the remaining dark chocolate batter over the top. Use the tip of a knife to swirl the batter, creating a marble effect without fully mixing the chocolates.
- Bake: Bake in the preheated oven for 20-25 minutes, or until the edges begin to pull away from the pan. Test doneness by inserting a toothpick into the center; it should come out with moist crumbs attached, not wet batter.
- Cool and Serve: Allow the brownies to cool in the pan on a wire rack. Once cooled, cut into 16 squares and enjoy this decadent dessert.
Notes
- Use high-quality chocolate for the best flavor and texture.
- Ensure eggs are at room temperature to help the batter blend smoothly.
- Do not overbake; moist crumbs on the toothpick indicate perfect fudginess.
- Line the pan with parchment paper for easy removal and clean slicing.
- Swirling the batter creates the distinctive marble effect – be gentle to preserve the pattern.
- Brownies can be stored airtight at room temperature for up to 3 days or refrigerated for 5 days.
