Ingredients

Scale

For the Sponge Cake

  • 4 large eggs, separated
  • ½ cup granulated sugar
  • 1 cup all-purpose flour
  • 1 tsp baking powder
  • ¼ tsp salt
  • 1 tsp vanilla extract
  • ¼ cup whole milk
  • 2 tbsp melted butter

For the White-Chocolate Filling

  • 8 oz white chocolate, chopped
  • ½ cup heavy cream
  • 8 oz mascarpone or cream cheese, softened
  • ½ cup powdered sugar
  • 1 tsp vanilla extract

For the Raspberry Ribbon

  • 1 cup fresh or frozen raspberries
  • 2 tbsp granulated sugar
  • 1 tbsp lemon juice
  • 1 tsp cornstarch (optional, for thickening)

For Decoration

  • Fresh raspberries
  • White-chocolate curls or shavings
  • Optional: whipped cream or white-chocolate ganache
  • Powdered sugar for a soft finish

Instructions

  1. Bake the Heart-Roll Sponge: Preheat your oven to 350°F (175°C) and line a 10×15-inch jelly-roll pan with parchment paper. In a bowl, beat the egg yolks with sugar until the mixture is pale, thick, and glossy. Stir in vanilla extract, whole milk, and melted butter. In a separate bowl, whisk the egg whites with a pinch of salt until soft peaks form. Gently fold the egg whites into the yolk mixture. Sift together the flour, baking powder, and salt, then fold these dry ingredients into the batter carefully until smooth. Spread the batter evenly in the prepared pan and bake for 10–12 minutes, or until the cake is springy to the touch.
  2. Shape the Cake: While the sponge is still warm, dust a clean kitchen towel with powdered sugar. Carefully invert the cake onto the towel, peel off the parchment paper, and roll the sponge from the short side into a tight roll. Let it cool completely in this shape to help set the heart roll’s structure.
  3. Make the Raspberry Ribbon: In a small saucepan, combine fresh or frozen raspberries, granulated sugar, and lemon juice. Simmer gently until the raspberries break down and form a sauce. If you prefer a thicker consistency, whisk in a cornstarch slurry. Strain the mixture to remove seeds and allow it to cool completely.
  4. Prepare the Filling: Melt the chopped white chocolate with heavy cream over low heat until smooth and combined, then allow to cool slightly. In a mixing bowl, beat mascarpone or cream cheese with powdered sugar and vanilla extract until creamy. Gently fold the melted white chocolate mixture into the mascarpone to create a silky, luscious filling.
  5. Assemble: Carefully unroll the cooled sponge cake. Spread the white-chocolate filling evenly over the surface. Drizzle the cooled raspberry sauce over the filling, then use a spatula to swirl it lightly creating a pretty ribbon effect. Re-roll the sponge tightly without the towel and place it seam-side down. Refrigerate for 20–30 minutes to let it set.
  6. Decorate: Just before serving, dust the cake lightly with powdered sugar. Garnish with fresh raspberries and white-chocolate curls or shavings. Optionally, add a glaze of whipped cream or white-chocolate ganache for a romantic sheen that enhances the presentation.

Notes

  • You can tint the white-chocolate filling with a drop of natural raspberry juice for a delicate pastel pink effect.
  • Rolling the sponge while warm prevents cracking and helps maintain flexibility.
  • Cooling the rolled sponge cake sets its shape, making it easier to handle.
  • Refrigerate the cake before slicing to ensure clean, elegant cuts and preserve the swirled pattern.
