Ingredients
For the Chocolate Sponge Cake:
-
4 large eggs, separated
-
¾ cup granulated sugar, divided
-
½ cup all-purpose flour
-
¼ cup cocoa powder, unsweetened
-
¼ teaspoon salt
-
¼ teaspoon cream of tartar (optional, helps egg whites stiffen)
-
2 tablespoons vegetable oil
-
2 tablespoons milk
-
½ teaspoon vanilla extract
For the Filling:
-
½ cup heavy cream
-
2 tablespoons powdered sugar
-
½ teaspoon vanilla extract
Optional Topping:
-
Cocoa powder or powdered sugar for dusting
-
Chocolate ganache for drizzling
Instructions
1. Preheat Oven and Prepare Pan:
Preheat the oven to 350°F (175°C). Line a 10×15-inch jelly roll pan with parchment paper and lightly grease it. This ensures the cake will release easily.
2. Prepare the Dry Ingredients:
Sift together flour, cocoa powder, and salt. Set aside.
3. Beat Egg Yolks:
In a bowl, whisk egg yolks with half of the sugar (about 3 tablespoons) until pale and creamy. Add milk, oil, and vanilla extract, mixing until smooth.
4. Beat Egg Whites:
In a separate clean bowl, beat egg whites with cream of tartar (if using) until soft peaks form. Gradually add the remaining sugar and continue beating until stiff peaks form.
5. Combine Wet and Dry Ingredients:
Gently fold the flour mixture into the egg yolk mixture until just combined. Then, carefully fold in the egg whites in three additions, maintaining the airiness. Do not overmix; this keeps the sponge light and fluffy.
6. Bake the Cake:
Pour the batter into the prepared pan and spread evenly. Bake for 12–15 minutes, or until the cake springs back when lightly touched. Do not overbake, or it may crack when rolling.
7. Prepare the Towel for Rolling:
While the cake bakes, lay a clean kitchen towel on a flat surface and sprinkle it lightly with powdered sugar.
8. Roll the Cake:
Immediately after removing the cake from the oven, invert it onto the sugared towel. Carefully peel off the parchment paper. Starting from the short edge, roll the cake with the towel inside. Let it cool completely in the rolled position. This prevents cracking when you add the filling.
9. Make the Filling:
Whip heavy cream with powdered sugar and vanilla until soft peaks form.
10. Fill and Re-roll:
Unroll the cooled cake gently. Spread the whipped cream evenly over the surface, leaving a small border at the edges. Carefully re-roll the cake without the towel. Place seam side down on a serving plate.
11. Optional Decoration:
Dust the top with cocoa powder or powdered sugar. For a richer treat, drizzle with chocolate ganache or melted chocolate.
12. Chill and Serve:
Refrigerate for at least 30 minutes before slicing to help the roll hold its shape. Use a sharp knife and cut gently for neat slices.
Tips for a Perfect Swiss Roll
-
Don’t Overbake: The cake must be soft and pliable; otherwise, it will crack when rolled.
-
Folding Carefully: Folding egg whites gently preserves the airiness of the sponge.
-
Use Fresh Ingredients: Fresh eggs and high-quality cocoa powder make a big difference.
-
Make Ahead: You can prepare the cake a day before and store it in the fridge. The flavor improves as it sits.
-
Variations: Try chocolate ganache, fruit jam, or cream cheese filling for different flavors.
