Japanese Sponge Cheesecake Recipe

Japanese sponge cheesecake, also known as cotton cheesecake or jiggly cheesecake, is a beloved dessert from Japan known for its cloud-like texture and delicate sweetness. It combines cream cheese, eggs, and a touch of milk into an incredibly light, moist cake that wobbles when you shake it. This recipe works because it uses a meringue folding technique and a low-temperature water bath, creating a stable, soufflé-like crumb that doesn’t crack.

Ingredients

6 large eggs, separated (about 200 g egg whites and 120 g yolks)
8 oz (225 g) cream cheese, softened
1/2 cup (120 ml) whole milk
1/2 cup (100 g) granulated sugar, divided
1/4 cup (30 g) cake flour, sifted
2 tbsp (15 g) cornstarch, sifted
1 tsp lemon juice or white vinegar (for stabilizing meringue)
1/4 tsp salt
1 tsp vanilla extract
2 tbsp (30 g) unsalted butter, melted (for greasing pan)

Instructions

Preheat your oven to 320°F (160°C). Grease a 9-inch (23 cm) round cake pan with butter and line the bottom with parchment paper. If using a springform pan, wrap the outside tightly with two layers of aluminum foil to prevent water from seeping in during the water bath.
Separate the eggs while cold. Place the whites in a clean, dry mixing bowl and the yolks in a separate bowl. Let both come to room temperature (about 15 minutes).
In a medium saucepan, heat the cream cheese and milk over low heat, stirring constantly until smooth and lump-free. Remove from heat and let cool for 5 minutes.
Whisk the egg yolks into the cream cheese mixture one at a time, then add the vanilla extract and salt. Mix until fully combined.
Sift the cake flour and cornstarch over the yolk mixture and whisk gently until no dry streaks remain. Set aside.
In a separate bowl, beat the egg whites with an electric mixer on medium speed until foamy. Add the lemon juice, then gradually add the sugar, 1 tablespoon at a time, while continuing to beat. Increase speed to high and beat until stiff, glossy peaks form—about 4 to 5 minutes. The meringue should hold a firm peak when the whisk is lifted.
Fold one-third of the meringue into the yolk mixture using a rubber spatula, cutting through the center and lifting from the bottom. This lightens the batter. Then gently fold in the remaining meringue in two additions, being careful not to deflate the air. The batter should be homogenous but still airy.
Pour the batter into the prepared pan. Tap the pan on the counter a few times to release large air bubbles.
Place the cake pan into a larger roasting pan. Pour hot water (about 160°F / 70°C) into the roasting pan until it reaches about 1 inch up the side of the cake pan. This water bath ensures even, gentle heat and prevents cracking.
Bake for 60 to 75 minutes, until the top is golden brown and a skewer inserted into the center comes out clean. The internal temperature of the cake should reach at least 160°F (71°C) (USDA FSIS safe minimum for egg dishes). If the top browns too quickly, loosely cover with foil after 30 minutes.
Turn off the oven and leave the cake inside with the door slightly ajar for 15 minutes. This gradual cooling prevents sudden shrinkage.
Remove the cake from the water bath and let cool in the pan on a wire rack for 30 minutes. Then carefully invert onto a serving plate (or run a knife around the edges and release the springform). Serve warm or at room temperature.

Tips

Use cake flour: Cake flour has lower protein than all-purpose, which gives a tender crumb. If you only have all-purpose, substitute 2 tbsp of it with cornstarch (so 2 tbsp all-purpose + 2 tbsp cornstarch for the total).
Don’t overmix the meringue: Overbeaten egg whites become dry and difficult to fold, deflating the batter. Stop when the peaks are stiff but still glossy.
Water bath is essential: Skipping it can cause the cake to crack and become dense. The steam keeps the oven moist and the heat gentle.
Cool gradually: Sudden temperature changes cause the cake to collapse. Always let it rest in the oven with the door open for 15 minutes before removing.

Serving Suggestions

Serve this cheesecake slightly warm or at room temperature, dusted with powdered sugar. It pairs beautifully with fresh berries, a drizzle of honey, or a dollop of lightly sweetened whipped cream. For a traditional Japanese touch, enjoy it with a cup of green tea or coffee.

Variations

Matcha: Add 1 tbsp of matcha powder to the flour mixture for a subtle earthy flavor.
Lemon: Add 1 tbsp of lemon zest to the cream cheese mixture for a bright citrus note.
Chocolate: Replace 1 tbsp of cake flour with 1 tbsp of unsweetened cocoa powder and add 2 oz (60 g) melted dark chocolate to the cream cheese mixture.
Less sweet: Reduce sugar to 1/3 cup (65 g) if you prefer a less sweet dessert.

Storage and Reheating

Store leftover cheesecake in an airtight container in the refrigerator for up to 4 days. To reheat, place a slice on a microwave-safe plate and heat for 15–20 seconds until just warm. You can also enjoy it cold, straight from the fridge. For longer storage, wrap the whole cake (or individual slices) tightly in plastic wrap and freeze for up to 1 month. Thaw overnight in the refrigerator before serving.

Frequently Asked Questions

Why did my cheesecake crack? Cracks usually happen from overbaking or a sudden temperature change. Make sure you use a water bath and cool the cake gradually in the oven. Also, avoid opening the oven door during baking.

Can I use a regular cake pan instead of a springform? Yes, but you’ll need to line it with parchment paper and leave enough overhang to lift the cake out. A springform is easier because you can simply release the sides.

My cake deflated after baking—what went wrong? This often occurs if the meringue was underbeaten or overfolded, or if the cake was removed from the oven too quickly. Ensure stiff peaks and fold gently. Also, never skip the 15-minute rest in the oven.

Can I make this gluten-free? Yes, replace the cake flour with a gluten-free all-purpose blend that contains xanthan gum. The texture may be slightly denser but still delicious.

Do I need a kitchen scale? Not strictly, but weighing the eggs and flour gives the most consistent results. If using cups, spoon the flour into the cup and level it off—don’t scoop directly.

Can I use low-fat cream cheese? It’s not recommended. Low-fat cream cheese has a higher water content, which can make the batter too loose and affect the cake’s structure. Use full-fat cream cheese for the best texture.
