Print Recipe Jump to Recipe

Chocolate Cake Roll (Swiss Roll) always looked impossibly fancy to me in bakery windows, and I used to think there was no way I could make one at home without special equipment or professional training. But the day I finally attempted this elegant dessert and successfully rolled that thin chocolate sponge around fluffy vanilla whipped cream without it cracking into a million pieces, I felt like an absolute baking genius. The secret is all in the rolling technique while the cake is still warm, and once you know that one trick, this becomes surprisingly doable.

What Is a Swiss Roll?

Chocolate Cake Roll (Swiss Roll) is a thin chocolate sponge cake baked in a sheet pan, rolled while warm with parchment paper to set its shape, then filled with vanilla whipped cream and covered with chocolate ganache. What makes this dessert special is the dramatic spiral pattern you see when you slice it and that incredibly light, airy texture from the whipped egg whites in the batter. The cake stays flexible enough to roll without cracking when you follow the proper cooling technique. Think of it as a show-stopping dessert that combines delicate sponge, fluffy cream, and rich chocolate in every beautiful slice.

Ingredients Breakdown

Let’s break down all the ingredients for this stunning Chocolate Cake Roll (Swiss Roll). I’ve organized everything by component so you can prep efficiently.

For the Chocolate Sponge Cake:

• Cake flour or all-purpose flour (¾ cup): Creates tender, delicate sponge. Either works perfectly.
• Unsweetened cocoa powder (¼ cup, plus extra for rolling): Natural or Dutch-process both work for chocolate flavor.
• Baking powder (1 teaspoon): Provides gentle lift for light texture.
• Salt (½ teaspoon): Balances sweetness and makes flavors pop.
• Eggs (4 large, separated, room temperature): Whites whipped separately create that airy sponge for your Chocolate Cake Roll (Swiss Roll).
• Granulated sugar (¾ cup, divided): Sweetens and stabilizes the whipped egg whites.
• Vegetable oil (¼ cup): Keeps the cake moist and flexible for rolling.
• Buttermilk or whole milk (¼ cup): Adds moisture and tender crumb.
• Vanilla extract (1½ teaspoons): Rounds out the chocolate flavor beautifully.
• Espresso powder (1 teaspoon, optional): Deepens chocolate flavor without adding coffee taste.

For the Vanilla Whipped Cream Filling:

• Cold heavy cream (1 cup): Must be very cold for proper whipping.
• Granulated or confectioners’ sugar (3 tablespoons): Sweetens the cream. Either type works perfectly.
• Vanilla extract (1 teaspoon): Classic vanilla flavor.
• Marshmallow creme (2 tablespoons, optional): Adds subtle marshmallow flavor and extra stability.

For the Chocolate Ganache Topping:

• Heavy cream (½ cup): Creates smooth, pourable ganache.
• Semi-sweet chocolate (4 ounces, finely chopped): Quality chocolate makes the best ganache for your Chocolate Cake Roll (Swiss Roll).
• Light corn syrup (1 teaspoon, optional): Adds beautiful glossy shine to the ganache.

Step-by-Step Instructions

Alright, let’s make this impressive dessert. The technique is crucial here, so follow each step carefully.

Prep Your Pan

Preheat your oven to 350°F. Grease a 12×17-inch baking pan thoroughly with nonstick spray or butter, then line it with parchment paper so the cake releases easily later. Grease the parchment paper too. You want an extremely nonstick surface for your Chocolate Cake Roll (Swiss Roll) to prevent any sticking.

Make the Chocolate Sponge

Using a fine mesh sieve, sift the cake flour, cocoa powder, baking powder, and salt together into a bowl. Set this aside.

Beat the egg whites and ¼ cup sugar together on high speed for 4-5 minutes until foamy medium peaks form. The peaks should have a slight droop and aren’t quite stiff. Transfer this to another bowl.

In the same bowl you just used for egg whites, add the egg yolks and remaining ½ cup sugar. Beat on high speed for 1 minute, then add the oil, buttermilk, vanilla, and espresso powder if using. Beat on high speed for 2 minutes until thin and slightly bubbly.

Add half the whipped egg whites into the yolk mixture and mix on low speed for 10 seconds. Repeat with the remaining egg whites and mix for another 10 seconds. Sift in the flour mixture and gently fold everything together with a silicone spatula until just combined. Don’t overmix or you’ll deflate the batter. The batter should be light and fluffy.

Bake the Cake

Spread the batter evenly into your prepared pan in a very thin layer. Shimmy the pan on the counter to smooth out the top. Bake for 12-14 minutes until the top springs back lightly when touched with your finger. Don’t overbake or the cake will crack when rolling.

Roll the Hot Cake

While the cake bakes, lay a piece of parchment paper or clean kitchen towel flat on the counter, larger than the cake. Dust it with about 2 tablespoons of cocoa powder using a fine mesh sieve. A kitchen towel works better to prevent cracking.

The moment the cake comes out of the oven, quickly run a knife around the edges to loosen it. Immediately flip it onto the prepared parchment or towel. Peel off the parchment that was on the bottom during baking. Starting with the narrow end, tightly roll the hot cake up with the parchment or towel. Do this slowly and gently for your Chocolate Cake Roll (Swiss Roll).

Let the cake cool completely at room temperature rolled up in the parchment or towel, about 3 hours. Don’t refrigerate it or it will crack when you unroll it. Slow cooling at room temperature is essential.

Make the Whipped Cream Filling

Whip the cold heavy cream, sugar, and vanilla extract on medium-high speed until medium to stiff peaks form, about 2-3 minutes. Beat in the marshmallow creme if using for extra flavor and stability.

Fill and Re-Roll

Slowly and gently unroll the cooled cake. Spread the whipped cream evenly on top, leaving about a ½-inch border around the edges. Gently roll the cake back up, this time without the parchment or towel. Place it on a wire rack set on a baking sheet to catch ganache drips later.

Make the Chocolate Ganache

Place the chopped chocolate and corn syrup if using in a medium bowl. Heat the cream in a small saucepan until it just begins to gently simmer. Don’t let it boil rapidly. Pour the hot cream over the chocolate and let it sit for 2-3 minutes to gently soften the chocolate. Slowly stir until completely smooth and glossy.

Pour the ganache all over your Chocolate Cake Roll (Swiss Roll). Spoon up any drips and pour them over the cake again for complete coverage. Refrigerate for at least 30-60 minutes before slicing and serving.

Serving This Elegant Dessert

This Chocolate Cake Roll (Swiss Roll) is best served chilled, sliced into beautiful spiral rounds that show off the gorgeous layers. I love serving it at special occasions and celebrations because it looks so impressive but is surprisingly achievable. The combination of light chocolate sponge, fluffy vanilla cream, and rich ganache makes it perfect for dinner parties and holidays. For a complete chocolate dessert spread, serve it alongside other chocolate treats like my Chocolate Fudge Layer Cake to give guests variety. Use a sharp knife wiped clean between cuts for the neatest slices.

Pro Tips for Success

• Room temperature eggs are essential: They whip to much greater volume and create lighter sponge for your Chocolate Cake Roll (Swiss Roll).
• Don’t overbake the cake: The cake should spring back lightly when touched. Overbaking makes it dry and prone to cracking when rolled.
• Roll while hot: This is crucial. The warm cake is flexible and sets into the rolled shape as it cools.
• Cool at room temperature: Never refrigerate the rolled cake while cooling. Cold makes it crack when you unroll it.
• Use a towel instead of parchment: A clean kitchen towel helps prevent cracking better than parchment paper.
• Whip cream to proper peaks: Medium to stiff peaks hold their shape in the roll without being too stiff to spread.
• Leave a border when filling: The ½-inch border prevents cream from squishing out the ends when you roll.
• Chill before slicing: The ganache needs time to set for clean, beautiful slices.
