Chubby Japanese Cheesecake Recipe (Cotton Soft)

Chubby Japanese cheesecake, also known as cotton cheesecake or soufflé cheesecake, is a cloud-like dessert that melts in your mouth. It’s made with cream cheese, eggs, sugar, and a touch of milk, then baked in a water bath to achieve its signature jiggle and ultra-soft texture. This recipe is genuinely reliable because it uses a stable meringue and a gentle baking method, giving you that tall, wobbly, and incredibly light cake every time.

Ingredients

8 oz (226 g) cream cheese, at room temperature
1/2 cup (120 ml) whole milk
1/4 cup (60 g) unsalted butter, cubed
6 large eggs, separated (yolks and whites), at room temperature
1/2 cup (100 g) granulated sugar, divided
1/4 cup (30 g) cake flour, sifted
2 tablespoons (16 g) cornstarch, sifted
1 teaspoon lemon juice (optional, for stability)
1/4 teaspoon cream of tartar (optional, for meringue)

Instructions

Preheat your oven to 325°F (160°C). Grease a 9-inch (23 cm) round springform pan and line the bottom with parchment paper. Wrap the outside of the pan tightly with aluminum foil to prevent water from seeping in during the water bath.
In a large heatproof bowl set over a pot of simmering water (or in the microwave in 30-second bursts), melt the cream cheese, milk, and butter together. Stir until smooth and no lumps remain. Remove from heat and let cool slightly.
Whisk the egg yolks into the cream cheese mixture one at a time, beating well after each addition. Add the lemon juice if using.
Sift the cake flour and cornstarch over the yolk mixture and whisk until just combined. Be careful not to overmix; set aside.
In a separate clean, dry bowl, beat the egg whites with an electric mixer on medium speed until foamy. Add the cream of tartar if using. Gradually add the sugar, 1 tablespoon at a time, while beating on high speed. Continue until stiff peaks form—the meringue should be glossy and hold a firm peak when the whisk is lifted.
Fold one-third of the meringue into the cream cheese mixture with a rubber spatula to lighten it. Then gently fold in the remaining meringue in two additions, using a cutting motion and turning the bowl. Be careful not to deflate the batter; it should be airy and smooth.
Pour the batter into the prepared pan. Tap the pan on the counter a few times to release large air bubbles.
Place the springform pan into a larger roasting pan. Pour hot water (about 1 inch/2.5 cm deep) into the roasting pan, creating a water bath. The water should come about halfway up the sides of the springform pan.
Bake for 60–70 minutes, or until the cake is golden brown on top and a skewer inserted in the center comes out mostly clean (a few moist crumbs are fine). The cake will still jiggle slightly in the center—that’s normal.
Turn off the oven and leave the cake inside with the door slightly ajar for 15 minutes. This gradual cooling helps prevent cracking.
Remove the cake from the water bath and let it cool completely in the pan on a wire rack. Once cool, run a knife around the edges and release the springform. Chill in the refrigerator for at least 2 hours before serving—this makes it easier to slice and improves the texture.

Tips

Use room-temperature ingredients: Cold eggs and cream cheese can make the batter lumpy and the meringue less stable. Set them out 30 minutes before starting.
Don’t skip the water bath: The steam from the hot water keeps the oven moist and ensures the cake rises evenly without cracking. If your springform pan isn’t leak-proof, wrap it in a double layer of foil.
Fold gently: Overmixing deflates the meringue and results in a dense, flat cake. Use a light hand and stop as soon as no streaks of white remain.
Meringue consistency: Stiff peaks are essential. If the meringue is too soft, the cake won’t rise properly. If it’s overbeaten, it will look curdled and be hard to fold.

Serving Suggestions

Serve chilled or at room temperature, dusted with powdered sugar. It’s delicious on its own, but you can also add a dollop of whipped cream, fresh berries, or a drizzle of honey. For a richer touch, serve with a spoonful of berry compote or chocolate sauce.

Variations

Matcha: Replace 1 tablespoon of cake flour with 1 tablespoon of matcha powder for a green tea version.
Lemon: Add 1 teaspoon of lemon zest to the yolk mixture for a bright citrus flavor.
Chocolate: Melt 2 oz (60 g) of dark chocolate with the cream cheese mixture, and reduce the flour by 1 tablespoon.
No cornstarch: If you don’t have cornstarch, use 1/3 cup (40 g) of cake flour in total and omit the cornstarch.

Storage and Reheating

Store the cheesecake in an airtight container in the refrigerator for up to 4 days. It’s best served cold or at room temperature. To freeze, wrap individual slices in plastic wrap and then foil; freeze for up to 2 months. Thaw overnight in the refrigerator before serving. Reheating is not recommended, as it will change the texture—enjoy it chilled.

Frequently Asked Questions

Why did my cheesecake crack on top? Cracks are usually caused by overcooking or a sudden temperature change. Make sure your oven isn’t too hot, and always let the cake cool gradually in the oven with the door ajar. Also, don’t overbeat the meringue—it should be smooth, not lumpy.

Can I use a regular round cake pan instead of a springform? Yes, but line it with parchment paper and leave enough overhang to lift the cake out. You may need to run a knife around the edges to release it. The baking time may be slightly shorter, so check at 50 minutes.

Why is my cheesecake dense and heavy? This usually means the meringue was deflated during folding, or the batter was overmixed. Be gentle and fold only until combined. Also, make sure your egg whites are at room temperature and free of any yolk.

Can I make this without a water bath? You can, but the cake is more likely to crack and may not rise as evenly. The water bath provides gentle, even heat. If you skip it, place a pan of hot water on the lower oven rack instead.

How do I know when it’s done? The top should be golden brown, and a skewer inserted in the center should come out with only a few moist crumbs. The center will still jiggle slightly—that’s the sign of a perfect cotton texture.

Can I use low-fat cream cheese? Low-fat cream cheese has a higher water content, which can make the cake less creamy and more prone to cracking. For best results, use full-fat cream cheese.
