These Raspberry Swirl Brownies combine rich, fudgy chocolate with a tart raspberry swirl for a dessert that’s as beautiful as it is delicious. Perfect for holidays, parties, or whenever you need a sweet pick-me-up!
Preheat the oven to 350°F (175°C). Line an 8×8-inch baking pan with parchment paper, leaving extra over the sides for easy removal.
Make the raspberry swirl: In a small saucepan, combine raspberries, sugar, and lemon juice. Cook over medium heat until the berries start breaking down. Stir in the cornstarch slurry and cook for 1–2 minutes until thickened. Set aside to cool.
Prepare the brownie batter: In a large bowl, whisk melted butter and sugar until smooth. Add eggs and vanilla, whisking until glossy.
Add dry ingredients: Sift in cocoa powder, flour, and salt. Gently stir until just combined—avoid overmixing. Fold in the chocolate chips.
Layer and swirl: Spread the brownie batter evenly into the pan. Drop spoonfuls of raspberry sauce over the top. Use a knife or toothpick to swirl the raspberry mixture into the batter.
Bake for 25–30 minutes, or until a toothpick inserted in the center comes out with moist crumbs.
Cool and serve: Let the brownies cool completely in the pan before slicing for clean edges.
Notes
Use frozen raspberries if fresh ones aren’t in season—just thaw and drain before cooking.
For extra fudgy brownies, pull them out of the oven when the center looks slightly underbaked.
Chill before cutting to help the layers set perfectly.
