Step-by-Step Instructions
Step 1: Prepare Your Baking Pan
- Preheat your oven to 350°F (175°C).
- Line a 10 x 15-inch jelly roll pan with parchment paper. This helps the cake release easily after baking.
Step 2: Separate the Eggs
- Carefully separate the egg whites from the yolks.
- Place the yolks in one bowl and the whites in another. Be sure no yolk sneaks into the whites, or your meringue might not whip up properly.
Step 3: Mix the Egg Yolk Batter
- In the bowl with the egg yolks, add half of the sugar (about ¼ cup / 50g), a pinch of salt, and the vanilla extract.
- Whisk until the mixture becomes pale and slightly thickened.
- Stir in the vegetable oil and milk.
- Gradually sift in the flour while gently mixing to avoid lumps. Your yolk batter should be smooth and free of clumps.
Step 4: Whip the Egg Whites
- In a clean mixing bowl, add the egg whites and cream of tartar.
- Use a hand mixer or stand mixer on medium speed to whip the egg whites until they become foamy.
- Gradually add the remaining sugar (¼ cup / 50g) while continuing to whip. Increase the mixer speed to high.
- Whip until you achieve medium to stiff peaks—when you lift the beaters, the peaks should hold their shape but still have a slight curl at the tip.
Step 5: Combine the Mixtures
- Take about one-third of the whipped egg whites and gently fold them into the egg yolk batter. This lightens the batter so it’s easier to incorporate the remaining whites.
- Add the rest of the egg whites in two more batches, folding carefully each time. Use a spatula and a gentle folding motion to avoid deflating the meringue. You want to keep as much air in the batter as possible.
Step 6: Pour and Bake
- Slowly pour the batter into the lined jelly roll pan, spreading it evenly. A spatula or offset knife works well to smooth the top.
- Tap the pan lightly on the countertop to release any large air bubbles.
- Bake in the preheated oven for 10–12 minutes, or until the top is a light golden color and springs back when touched.
Step 7: Cool and Roll
- Once baked, remove the cake from the oven and carefully lift it out of the pan using the parchment paper.
- Place it on a wire rack to cool for a few minutes.
- While it’s still slightly warm, place another sheet of parchment on top and gently flip the cake over. Peel off the bottom parchment.
- Roll the cake up (without the filling) in the new parchment paper and let it cool completely in this rolled shape. This “pre-rolling” helps the cake remember its shape and prevents cracking later.
Step 8: Add the Filling
- Unroll the cooled cake carefully.
- Spread your whipped cream or sweetened filling evenly across the surface, leaving a small border at the edges to prevent spillage.
- Gently re-roll the cake, using the parchment to guide you.
- Wrap it in plastic wrap to help it hold its shape and refrigerate for at least 30 minutes to set.
Step 9: Slice and Serve
- Unwrap the chilled cake and place it on a cutting board.
- Trim off the uneven edges for a clean presentation.
- Slice into individual servings.
- Garnish with powdered sugar, fresh fruit, or a drizzle of chocolate if you’d like. Enjoy your Japanese Cotton Candy Swiss Cake Roll in all its fluffy glory!

What to Serve With Japanese Cotton Candy Swiss Cake Roll
A light, airy cake roll pairs beautifully with a variety of sides and beverages. Here are a few ideas to make your dessert experience even more delightful:
- Fresh Fruit Salad: The natural sweetness of berries, kiwis, and mangoes complements the cake’s soft texture.
- Green Tea or Matcha Latte: The slightly bitter notes of green tea balance the sweetness of the cake.
- Fruit-Infused Water: Keep things light and refreshing with a simple cucumber and mint water, or add slices of lemon for a zesty twist.
- Whipped Cream and Berries: If you want to add an extra layer of indulgence, serve each slice with a dollop of whipped cream and fresh berries on the side.
- Ice Cream: A scoop of vanilla or strawberry ice cream can turn your cake roll into an even more decadent treat.
Experiment with different sides to find your perfect pairing. Whether you keep it simple or go all out, this cake is guaranteed to shine as the star of your dessert table.
Top Tips for Perfecting Japanese Cotton Candy Swiss Cake Roll
- Use Room-Temperature Eggs: Cold eggs are harder to whip into a stable foam. Let them sit at room temperature for about 30 minutes before starting.
- Don’t Overmix the Batter: Overmixing can deflate your whipped egg whites. Use gentle folding motions to keep the batter airy.
- Test for Doneness: Check the cake at the 10-minute mark. If it springs back lightly when touched, it’s likely ready. Overbaking can lead to a dry, less flexible cake.
- Pre-Roll While Warm: Rolling the cake while it’s still slightly warm helps prevent cracks. If it cools completely flat, it may crack when you try to roll it later.
- Choose the Right Filling Consistency: Your filling should be thick enough to stay put when the cake is rolled. If it’s too runny, it might ooze out.
- Adjust Sweetness: If you prefer less sweetness, reduce the sugar slightly in both the batter and the filling.
- Experiment with Flavors: Don’t be afraid to add a pinch of matcha powder, cocoa powder, or a flavored extract to switch things up.
Following these tips will help you achieve a perfectly fluffy, crack-free Japanese Cotton Candy Swiss Cake Roll every time.
Storing and Reheating Tips
- Refrigeration: After you’ve rolled and filled the cake, wrap it tightly in plastic wrap. It will stay fresh for up to 2–3 days in the refrigerator. Make sure to keep it chilled, especially if you’re using whipped cream or other dairy-based fillings.
- Freezing: If you want to store it for a longer period, place the wrapped cake in a freezer-safe container or zip-top bag. It can stay frozen for up to 2 months. For best results, thaw it overnight in the refrigerator before serving.
- Reheating: Generally, this cake is best served chilled. If you prefer it slightly warm, you can let it sit at room temperature for 15–20 minutes before slicing. However, avoid using the microwave or oven to reheat, as this can melt the filling and alter the cake’s delicate texture.
By following these guidelines, you’ll keep your cake roll fresh and tasty, ensuring you can enjoy it whenever you get a craving for something sweet.

FAQ
- Can I make this recipe without cream of tartar?
Yes! If you don’t have cream of tartar, you can use a small amount of lemon juice or white vinegar to help stabilize the egg whites. - Is it okay to use cake flour instead of all-purpose flour?
Absolutely. Cake flour will make the cake even lighter, but reduce the quantity slightly (by about 2 tablespoons) to prevent the batter from becoming too delicate. - Can I fill the cake with jam or custard instead of whipped cream?
Of course! Feel free to get creative with fillings like fruit jam, custard, or even chocolate ganache. Just ensure the filling isn’t too runny. - Why did my cake crack when I rolled it?
Cracking often happens if the cake is overbaked or has cooled completely before rolling. Rolling it gently while it’s still warm can help avoid cracks. - How can I reduce the sweetness in this recipe?
You can cut down on the sugar by about 1–2 tablespoons in both the batter and the filling. Keep in mind that reducing sugar may affect the cake’s overall texture slightly. - What’s the best way to slice the roll neatly?
Use a sharp, serrated knife and wipe the blade clean between each slice. This prevents smearing of the filling and ensures clean cuts. - Can I double the recipe for a bigger cake?
Yes, you can. However, be sure to use a larger baking pan and adjust the baking time accordingly. Keep an eye on the cake to prevent overbaking.
