Ingredients
Scale
For the Chocolate Sponge Cake
- 1 cup All-Purpose Flour (can be swapped with gluten-free flour blend)
- 1/3 cup Dutch-Processed Cocoa Powder (ensure high-quality brand)
- 1 teaspoon Baking Powder (check freshness)
- 1/4 teaspoon Salt (enhances chocolate flavor)
- 4 large Egg Yolks (adds richness)
- 1 cup Caster Sugar (granulated sugar can be substituted)
- 1/4 cup Melted Butter (unsalted recommended)
- 1 teaspoon Vanilla Extract (or vanilla bean paste)
- 4 large Egg Whites (beat to stiff peaks)
For the Filling
- 1 cup Heavy Cream (ensure cold before whipping)
- 2 tablespoons Powdered Sugar (adjust to taste)
- 1/2 cup Mascarpone Cheese (can be replaced with cream cheese or omitted)
- 1 teaspoon Vanilla Extract (added to cream for flavor)
For the Chocolate Sauce
- 4 oz Dark Chocolate (semi-sweet can be used)
- 2 tablespoons Butter (preferably unsalted)
- 2 tablespoons Brown Sugar
Instructions
- Preheat and Prepare Pan: Preheat your oven to 350°F (180°C). Grease a 10×15 inch jelly roll pan, line it with parchment paper, and grease the parchment paper again to ensure the sponge does not stick.
- Mix Dry Ingredients: Sift together all-purpose flour, Dutch-processed cocoa powder, baking powder, and salt into a bowl. This ensures even distribution and a light texture.
- Combine Yolks and Sugar: In a separate bowl, whisk the egg yolks with half of the caster sugar, melted butter, and vanilla extract until smooth and slightly pale.
- Beat Egg Whites: In another clean bowl, beat the egg whites with the remaining caster sugar until stiff peaks form, creating a meringue that will give the sponge cake its airy texture.
- Fold Meringue into Yolks: Gently fold the stiff egg whites into the yolk mixture, being careful to maintain the air to keep the batter light.
- Incorporate Dry Ingredients: Carefully fold the sifted dry ingredients into the combined egg mixture, mixing until just combined without deflating the batter.
- Bake the Cake: Spread the batter evenly into the prepared jelly roll pan. Bake in the preheated oven for 12-15 minutes or until the cake springs back lightly when touched and a toothpick comes out clean.
- Roll the Hot Sponge: Immediately invert the cake onto a clean kitchen towel dusted lightly with cocoa powder. Carefully peel off the parchment paper and roll the cake up in the towel while still hot. Allow it to cool completely rolled to hold its shape.
- Prepare the Filling: In a chilled bowl, whip the heavy cream with powdered sugar and vanilla extract until it reaches soft peaks. Add the mascarpone cheese and continue whipping until stiff peaks form, creating a rich, stable filling.
- Fill and Re-roll the Cake: Unroll the completely cooled sponge, spread the whipped mascarpone filling evenly over the surface, then carefully roll it up again without the towel. Wrap tightly in plastic wrap and refrigerate for at least 30 minutes to set.
- Melt Chocolate Sauce: In a small saucepan over low heat, melt the dark chocolate with butter and brown sugar, stirring continuously until smooth and combined. Remove from heat.
- Serve: Unwrap the chilled Swiss roll and place it on a serving platter. Pour the warm chocolate sauce evenly over the roll just before slicing and serving.
Notes
- Use fresh baking powder to ensure proper rise of the sponge.
- Be gentle when folding the egg whites to keep the batter light and fluffy.
- Rolling the cake while hot prevents cracking by creating flexibility in the sponge.
- Ensure the heavy cream is well chilled before whipping for best volume.
- For a gluten-free version, substitute the all-purpose flour with a gluten-free flour blend.
- You can substitute mascarpone cheese with cream cheese if preferred or omit it altogether for a lighter filling.
- The chocolate sauce can be prepared in advance and gently reheated before serving.
