This image shows a chocolate Swiss roll cake with three visible layers: a dark chocolate outer frosting layer with smooth, slightly textured ridges, a soft and moist dark brown chocolate sponge cake layer inside it, and a thick white creamy filling swirled inside the sponge. The roll is sliced, revealing the spiral pattern of the chocolate sponge and white cream layers. The cake rests on white parchment paper on a white marbled surface.

Ingredients

3/4 cup (95g) cake flour or all-purpose flour (spooned & leveled)
1/4 cup (21g) unsweetened natural or Dutch-process cocoa powder, plus more for rolling

1 teaspoon baking powder
1/2 teaspoon salt

4 large eggs, at room temperature and separated
3/4 cup (150g) granulated sugar, divided

1/4 cup (60ml) vegetable oil
1/4 cup (60ml) buttermilk or whole milk
1 and 1/2 teaspoons pure vanilla extract

1 teaspoon espresso powder (optional)
1 cup (240ml) cold heavy cream or heavy whipping cream
3 tablespoons (38g) granulated sugar or confectioners’ sugar

1 teaspoon pure vanilla extract
Optional: 2 tablespoons marshmallow creme (“Fluff”)
1/2 cup (120ml) heavy cream or heavy whipping cream

One 4 ounce bar (113g) semi-sweet chocolate, finely chopped
Optional for glossy shine: 1 teaspoon light corn syrup

Instructions

Step 1: Preheat the oven to 350°F (177°C). Grease a 12×17-inch baking pan with nonstick spray or butter, then line it with parchment paper. Spray or grease the parchment as well for a nonstick surface.

Step 2: Sift the cake flour, cocoa powder, baking powder, and salt together using a fine mesh sieve. Set aside.
Step 3: In a clean bowl, beat the egg whites with 1/4 cup (50g) granulated sugar on high speed until medium peaks form, about 4–5 minutes. Transfer to another bowl.
Step 4: Using the same mixing bowl, beat the egg yolks with the remaining sugar on high speed for 1 minute. Add the oil, milk, vanilla, and espresso powder, then beat for 2 minutes until thin and slightly bubbly.

Step 5: Gently fold half the whipped egg whites into the yolk mixture on low speed for 10 seconds, then repeat with the remaining egg whites.
Step 6: Sift the flour mixture into the batter and fold with a silicone spatula until just combined. Be careful not to over-mix; the batter should remain light and fluffy.
Step 7: Spread the batter evenly into the prepared pan into a thin layer. Smooth the top by shimmying the pan on the counter. Bake for 12–14 minutes until the top springs back lightly when touched. Avoid over-baking.

Step 8: While baking, prepare a piece of parchment paper or a thin kitchen towel larger than the cake. Dust it with about 2 tablespoons of cocoa powder using a fine mesh sieve.
Step 9: Once the cake is done, loosen the edges with a knife and quickly invert it onto the cocoa-dusted parchment or towel. Remove the parchment paper that baked with the cake. Starting at the narrow end, gently roll the cake up with the parchment or towel. Let cool completely rolled, about 3 hours at room temperature.
Step 10: Whip the heavy cream, sugar, and vanilla extract on medium-high speed until medium to stiff peaks form, about 2–3 minutes. If using, fold in the marshmallow creme.

Step 11: Carefully unroll the cooled cake and spread the whipped cream evenly on top, leaving a 1/2-inch border. Roll the cake back up tightly without the parchment or towel. Place on a wire rack over a baking sheet.
Step 12: For the ganache, place chopped chocolate and corn syrup (if using) in a bowl. Heat cream until it just simmers and pour over the chocolate. Let sit 2–3 minutes, then stir until smooth and glossy.
Step 13: Pour the ganache evenly over the cake roll. Spoon extra ganache over any drips. Refrigerate the cake for at least 30–60 minutes before slicing.

Tips & Variations

Use a kitchen towel for rolling the hot cake instead of parchment for fewer cracks.
Espresso powder enhances the chocolate flavor but is optional.
To make a marshmallow whipped cream, gently fold in marshmallow creme after whipping.

For a glossy ganache, add 1 teaspoon light corn syrup to the chocolate before adding cream.
You can substitute buttermilk with whole milk if needed.

Storage

Store the cake covered in the refrigerator for up to 3 days. For best texture, allow the cake to come to room temperature for 15–20 minutes before serving. Leftovers can be gently reheated in a warm oven for a few minutes, but avoid microwave heating to preserve texture.

How to Serve

Several slices of chocolate roll cake are closely placed on a white marbled surface. Each slice shows three layers: a dark brown, soft chocolate sponge cake rolled with a thick, white cream layer inside, creating a visible spiral pattern. The outer edge of each slice is coated with a smooth, dark chocolate glaze. The texture of the cake looks moist and fluffy, while the cream is smooth and airy. photo taken with an iphone --ar 4:5 --v 7

FAQs

Can I use all-purpose flour instead of cake flour?

Yes, you can use all-purpose flour, but for a lighter texture, spoon and level the flour carefully to avoid adding too much.

How do I prevent the cake from cracking when rolling?

Rolling the cake while it is still warm using a parchment or kitchen towel dusted with cocoa powder helps prevent cracking. Let the cake cool completely rolled before unrolling to add the filling.
