Ingredients for Chocolate Swiss Roll

To create this delicious and elegant dessert, you’ll need a combination of ingredients for the sponge cake, the whipped cream filling, and the rich chocolate ganache topping. Each component brings a layer of flavor and texture, resulting in a perfect balance of lightness and richness.

• Eggs (6 large, room temperature, separated) – The key to a light and airy sponge cake. Separating the eggs helps create volume in the batter.
• Granulated sugar (2/3 cup, divided) – Used in both the egg yolk and egg white mixtures for sweetness and structure.
• Melted butter (3 tablespoons, cooled) – Adds richness and moisture to the cake without making it dense.
• Full-fat sour cream (2 tablespoons) – Sour cream enhances the tenderness of the sponge and gives a subtle tang to balance the sweetness.
• Vanilla extract (1 ½ teaspoons) – A classic addition that rounds out the flavors with warmth and depth.
• All-purpose flour (1/3 cup) – The base of the cake, providing structure without making it too heavy.
• Cocoa powder (1/3 cup) – Essential for that rich chocolate flavor in the sponge cake.
• Espresso powder (1 teaspoon, optional) – Intensifies the chocolate flavor, though it’s optional if you prefer to leave it out.

Whipped Cream Filling

The light and airy filling that brings sweetness and contrast to the chocolate sponge.

• Heavy whipping cream (1 cup) – This is whipped to create a light, fluffy filling for the roll.
• Granulated sugar (3 tablespoons) – Sweetens the cream while keeping it light.
• Vanilla extract (1 teaspoon) – Adds extra flavor to the whipped cream filling.

Chocolate Ganache Topping

A rich and glossy topping that adds the final touch of indulgence.

• Heavy cream (½ cup) – The base of the ganache, creating a smooth and rich topping.
• Corn syrup (1 tablespoon) – Helps to keep the ganache shiny and smooth.
• Semi-sweet melting chocolate (5 oz) – Use a high-quality chocolate to ensure the ganache is rich and decadent.

How to Make Chocolate Swiss Roll

Making a Swiss roll can seem intimidating, but with these simple steps, you’ll find that it’s an approachable and fun baking project. The secret to success lies in proper preparation and carefully following each step to achieve the perfect rolled cake.

1. Prepare the Cake Batter
   The first step is preparing the cake batter. Separate the eggs and whip the egg whites into stiff peaks with half of the sugar. Then, in a separate bowl, beat the egg yolks with the remaining sugar until pale and thick. Gently fold in the flour, cocoa powder, and espresso powder, along with the melted butter and sour cream. Finally, fold in the whipped egg whites to lighten the batter.
2. Bake the Cake
   Pour the batter onto a prepared baking sheet lined with parchment paper. Smooth it out evenly and bake for 12-14 minutes, until the cake springs back when touched. Be careful not to overbake!
3. Roll the Cake
   After baking, invert the cake onto a tea towel dusted with icing sugar or cocoa powder. Roll the warm cake in the towel to form the Swiss roll shape. Let it cool completely in the rolled shape before unrolling to add the filling.
4. Whip the Cream Filling
   While the cake is cooling, whip the heavy cream with sugar and vanilla extract until medium-firm peaks form. This will be the filling for the Swiss roll.
5. Fill and Roll the Cake
   Unroll the cooled cake, spread the whipped cream filling evenly across the surface, and then gently roll the cake back up, starting from one end. Use the tea towel to help guide the roll.
6. Make the Chocolate Ganache
   Heat the cream and corn syrup in the microwave until steaming, then pour over the chopped semi-sweet chocolate. Stir until smooth and glossy. Let the ganache cool slightly to thicken before pouring it over the rolled cake.
7. Finish and Chill
   Place the rolled cake on a cooling rack and pour the ganache over the top, letting it drip down the sides. Refrigerate for about an hour to set the ganache before slicing and serving.

This classic Swiss roll is not only a delight to eat but also a joy to make, offering a stunning presentation perfect for any occasion!

How Long to Bake Chocolate Swiss Roll

Baking the sponge cake for a Swiss roll is a quick process, but timing is critical to achieve the right texture. You want the cake to be soft and flexible, which allows it to roll without cracking. Here’s how to get the perfect bake:

• Baking Time: The sponge cake should bake at 350°F for about 12-14 minutes.
  • You’ll know it’s ready when it starts to pull away from the edges of the pan and springs back when gently pressed with a finger.
  • Be cautious not to overbake it, as that can lead to a dry cake that cracks when you try to roll it.

How to Roll the Swiss Roll Cake

Rolling the cake while it’s still warm is a crucial step to prevent cracking. Follow these steps to ensure a perfect roll:

1. Dust a Tea Towel: As soon as the cake comes out of the oven, dust a large tea towel with icing sugar or cocoa powder to prevent the cake from sticking.
2. Invert the Cake: Carefully turn the cake out onto the towel, then peel off the parchment paper.
3. Roll While Warm: Starting from the shorter edge, gently roll the cake up with the towel inside. This helps form the shape while the cake is still warm and pliable.
4. Let it Cool: Allow the rolled cake to cool completely at room temperature for about an hour before unrolling it to add the whipped cream filling.

Storing Chocolate Swiss Roll

If you have any leftovers (though that might be unlikely!), here’s how to store your Swiss roll to keep it fresh and delicious:

• In the Refrigerator:
  • The Swiss roll can be stored in the refrigerator for up to 3 days. Make sure it is covered or placed in an airtight container to prevent it from drying out.
• In the Freezer:
  • To store for longer, wrap the roll tightly in plastic wrap and then foil before freezing. You can freeze it for up to 3 months. When ready to serve, allow it to thaw in the fridge for a few hours or overnight.

Cooking Tips for the Perfect Swiss Roll

Achieving that perfect roll and soft sponge requires a bit of care, but these tips will help ensure success:

• Room Temperature Eggs: Make sure your eggs are at room temperature before starting. This helps them whip up more easily, leading to a lighter sponge.
• Do Not Overbake: Overbaking can make the cake dry and prone to cracking. Keep a close eye on the bake time and check the cake by pressing gently – it should spring back lightly.
• Gentle Folding: When folding in the egg whites, be gentle to keep the batter light and airy. Overmixing can deflate the egg whites and result in a denser cake.
• Rest the Cake: After adding the ganache, give the cake time to rest in the refrigerator so the ganache can fully set before slicing.

Following these tips will ensure your Chocolate Swiss Roll turns out soft, moist, and perfectly rolled every time!
