Japanese Air Cheesecake Recipe: Fluffy & Jiggly

Japanese air cheesecake, also known as cotton cheesecake or soufflé cheesecake, is a beloved dessert from Japan known for its cloud-like texture that literally jiggles when you cut into it. Unlike its dense New York counterpart, this cheesecake is made with a whipped meringue folded into a cream cheese batter, creating an airy, soufflé-like crumb that melts in your mouth. It works because the whipped egg whites provide structure and lift, while the cream cheese adds a rich, tangy flavor that stays surprisingly light.

Ingredients

8 oz (226 g) cream cheese, room temperature
1/2 cup (120 ml) whole milk
1/4 cup (60 g) unsalted butter
6 large eggs, separated (room temperature)
3/4 cup (150 g) granulated sugar, divided
1/4 cup (30 g) cake flour
2 tablespoons (16 g) cornstarch
1 teaspoon lemon juice
1/2 teaspoon vanilla extract
1/4 teaspoon salt

Instructions

Prep the pan and oven: Preheat your oven to 320°F (160°C). Grease a 9-inch (23 cm) round cake pan and line the bottom with parchment paper. Wrap the outside of the pan with a double layer of aluminum foil to prevent water from seeping in during the water bath.
Melt the cream cheese mixture: In a large heatproof bowl set over a pot of simmering water (or in a microwave in 30-second bursts), combine the cream cheese, milk, and butter. Stir until completely smooth and no lumps remain. Remove from heat and let cool for 5 minutes.
Add yolks and dry ingredients: Whisk the egg yolks into the cream cheese mixture one at a time, then add the lemon juice and vanilla. Sift the cake flour, cornstarch, and salt over the mixture and whisk until just combined. Set aside.
Whip the egg whites: In a clean, dry bowl, beat the egg whites with an electric mixer on medium speed until foamy. Gradually add 1/2 cup (100 g) of the sugar, a tablespoon at a time, and continue beating until stiff, glossy peaks form (about 5-7 minutes). The meringue should hold a firm peak when the whisk is lifted.
Fold the meringue: Add one-third of the meringue to the cream cheese batter and whisk gently to lighten it. Then fold in the remaining meringue in two additions, using a spatula, until no white streaks remain. Be careful not to deflate the mixture.
Pour and bake: Pour the batter into the prepared pan. Smooth the top with a spatula. Place the cake pan in a larger roasting pan and fill the roasting pan with hot water until it reaches halfway up the sides of the cake pan. Bake for 60-75 minutes, or until the top is golden brown and a skewer inserted into the center comes out clean (the cake should still jiggle slightly in the center).
Cool in the oven: Turn off the oven and leave the cheesecake inside with the door slightly ajar for 1 hour. This gradual cooling prevents the cake from collapsing.
Chill: Remove the cake from the water bath and let it cool completely on a wire rack. Then refrigerate for at least 2 hours (or overnight) before unmolding and serving.

Tips

Room temperature ingredients are crucial: Bring the cream cheese, eggs, and milk to room temperature before starting. Cold ingredients will cause the batter to curdle or the meringue to break.
Don’t overmix the meringue: Stop beating the egg whites as soon as they form stiff peaks. Overwhipping will make them dry and hard to fold in, resulting in a dense cake.
Use a water bath: The water bath provides gentle, even heat and keeps the cheesecake moist. Make sure the foil is secure to prevent water from leaking into the cake.
Cool gradually: The sudden temperature change can cause the cheesecake to sink. Always cool it in the oven with the door open for at least an hour.

Serving Suggestions

Serve the Japanese air cheesecake chilled, either plain or dusted with powdered sugar. It pairs beautifully with a dollop of lightly sweetened whipped cream, fresh berries, or a drizzle of honey or fruit coulis. For a classic Japanese café experience, serve it with a side of matcha green tea or a light black tea.

Variations

Matcha: Add 1 tablespoon of matcha powder to the dry ingredients for a green tea version.
Lemon: Increase the lemon juice to 2 tablespoons and add 1 teaspoon of lemon zest for a brighter citrus flavor.
Chocolate: Replace 2 tablespoons of cake flour with 2 tablespoons of unsweetened cocoa powder.
No water bath: If you prefer, you can bake without a water bath, but the texture will be less moist and the top may crack. Place a pan of hot water on the bottom oven rack instead.

Storage and Reheating

Store the cheesecake in an airtight container in the refrigerator for up to 4 days. It is best served cold, so no reheating is needed. You can also freeze the cheesecake for up to 1 month. Wrap it tightly in plastic wrap and then foil. Thaw overnight in the refrigerator before serving.

Frequently Asked Questions

Why did my cheesecake collapse? The most common reasons are underwhipped egg whites, overmixing the batter, or cooling it too quickly. Make sure your meringue is stiff and fold gently. Always cool the cake in the oven with the door ajar.

Can I use all-purpose flour instead of cake flour? Yes, you can substitute cake flour with all-purpose flour, but the texture will be slightly denser. To mimic cake flour, replace 2 tablespoons of all-purpose flour with 2 tablespoons of cornstarch.

Why did my cheesecake crack? Cracks are usually caused by baking at too high a temperature or overbaking. Use an oven thermometer to ensure your oven is accurate, and check the cake at the 60-minute mark. The center should still jiggle slightly.

Can I make this without a water bath? Yes, but the texture will be drier and the top may crack. If you skip the water bath, place a pan of hot water on the bottom rack of the oven to add humidity.

How do I know when it’s done? The cheesecake is done when a skewer inserted into the center comes out clean, but the center still has a slight jiggle. It will continue to set as it cools.

Can I use a springform pan? Yes, a springform pan works well. Just make sure to wrap the outside tightly with foil to prevent water from leaking in.
