Description

These raspberry swirl brownies are rich, fudgy, and beautifully marbled with tangy raspberry jam and fresh berries. The perfect twist on a classic brownie, they’re as elegant as they are indulgent.


Ingredients

  • 1/2 cup unsalted butter (1 stick)
  • 6 oz dark chocolate, chopped
  • 1/2 cup granulated sugar
  • 1/2 cup brown sugar
  • 2 large eggs
  • 1 tsp vanilla extract
  • 1/2 cup all-purpose flour
  • 1/4 cup unsweetened cocoa powder
  • 1/4 tsp salt
  • 1/3 cup raspberry jam or preserves
  • 1/2 cup fresh or frozen raspberries

Instructions

  1. Preheat oven to 350°F (175°C). Line an 8×8-inch square baking pan with parchment paper.
  2. Melt the butter and dark chocolate together in a heatproof bowl, stirring until smooth. Let cool slightly.
  3. In a separate bowl, whisk granulated sugar, brown sugar, eggs, and vanilla until glossy.
  4. Stir the melted chocolate mixture into the egg mixture until fully combined.
  5. Fold in flour, cocoa powder, and salt just until incorporated—do not overmix.
  6. Pour most of the batter into the prepared pan and smooth the top.
  7. Warm raspberry jam slightly to make it easier to spread. Dollop over the batter along with the raspberries.
  8. Swirl gently with a knife, then top with remaining brownie batter and another light swirl.
  9. Bake for 25–30 minutes, until edges are set and the center is still slightly soft.
  10. Cool completely in the pan before slicing into 12 to 16 brownies.

Notes

  • Use seedless jam for a smoother texture, if preferred.
  • Add chocolate chunks to the batter for extra richness.
  • Swap raspberries for strawberries or cherries for a different flavor twist.
  • Cool fully before slicing to ensure clean cuts and fudgy texture.
  • Store at room temperature or in the fridge; microwave briefly to reheat.
