Japanese soft cheesecake, also known as cotton cheesecake or soufflé cheesecake, is a cloud-like dessert that melts in your mouth. Unlike its dense American cousin, this version relies on a whipped meringue folded into a cream cheese base, giving it an airy, jiggly texture that’s more soufflé than cheesecake. It’s baked in a water bath at a low temperature, which keeps the crumb tender and prevents cracking. This recipe is designed to be foolproof, with precise steps to help you achieve that signature wobble without the dreaded deflate.
Ingredients
- 8 oz (226 g) cream cheese, at room temperature
- 1/2 cup (120 ml) whole milk
- 1/4 cup (60 g) unsalted butter, melted and cooled
- 6 large eggs, separated, at room temperature
- 1/4 cup (30 g) cake flour, sifted
- 1/4 cup (30 g) cornstarch, sifted
- 1/2 cup (100 g) granulated sugar, divided
- 1 teaspoon lemon juice (optional, for stability)
- 1/4 teaspoon salt
- Powdered sugar, for dusting (optional)
Instructions
- Preheat your oven to 325°F (160°C). Line the bottom of a 9-inch (23 cm) round springform pan with parchment paper. Wrap the outside of the pan tightly with two layers of aluminum foil to prevent water from seeping in during the water bath.
- In a large bowl, beat the cream cheese with an electric mixer on medium speed until smooth and creamy, about 2 minutes. Add the milk and melted butter, and beat until fully combined and no lumps remain.
- Add the egg yolks one at a time, beating well after each addition. Scrape down the sides of the bowl as needed.
- Sift the cake flour, cornstarch, and salt into the cream cheese mixture. Mix on low speed just until combined — do not overmix. Set aside.
- In a separate clean, dry bowl, beat the egg whites with the lemon juice (if using) on medium speed until foamy. Gradually add the sugar, 1 tablespoon at a time, while continuing to beat. Increase speed to high and beat until stiff peaks form — the meringue should hold a firm peak when the beaters are lifted, but not be dry or grainy.
- Gently fold one-third of the meringue into the cream cheese mixture using a rubber spatula, using a cutting motion to lighten the batter. Then fold in the remaining meringue in two additions, being careful not to deflate the air. The batter should be smooth and airy, with no white streaks.
- Pour the batter into the prepared pan and smooth the top with a spatula. Tap the pan gently on the counter a few times to release large air bubbles.
- Place the springform pan into a larger roasting pan. Pour hot water (not boiling) into the roasting pan until it comes about 1 inch (2.5 cm) up the sides of the springform pan.
- Bake for 30 minutes at 325°F (160°C), then reduce the oven temperature to 300°F (150°C) and continue baking for another 40 minutes, or until the cheesecake is set around the edges but still slightly jiggly in the center. The top should be golden brown.
- Turn off the oven, crack the oven door open, and let the cheesecake cool inside for 1 hour. This gradual cooling helps prevent cracking and shrinking.
- Remove the cheesecake from the water bath and let it cool completely on a wire rack. Then refrigerate for at least 4 hours, or overnight, before serving. This helps the cake set and makes it easier to slice.
- To serve, run a knife around the edges, release the springform, and dust with powdered sugar if desired.
Tips
- Room temperature ingredients are key: Cold cream cheese and eggs will create lumps and make the meringue less stable. Let them sit on the counter for 30–60 minutes before starting.
- Don’t overfold: Folding the meringue too vigorously or too many times will deflate the batter, resulting in a dense, flat cheesecake. Fold until just combined — a few streaks are okay.
- Water bath is non-negotiable: The steam from the water bath keeps the cheesecake moist and prevents the top from cracking. If you skip it, the cake will likely dry out and sink.
- Cool slowly: Sudden temperature changes cause the cake to collapse. Always cool in the oven with the door ajar, then at room temperature, then in the fridge.
Serving Suggestions
Serve chilled or at room temperature. A light dusting of powdered sugar is classic, but you can also top it with fresh berries, a drizzle of honey, or a dollop of whipped cream. It pairs beautifully with green tea or coffee. For a more decadent twist, serve with a spoonful of strawberry compote or lemon curd.
Variations
- Matcha: Add 1 tablespoon of matcha powder to the dry ingredients for a subtly bitter, earthy flavor.
- Lemon: Add the zest of one lemon to the cream cheese mixture and replace the lemon juice in the meringue with 1 teaspoon of lemon extract.
- Chocolate: Replace 2 tablespoons of cake flour with 2 tablespoons of unsweetened cocoa powder.
- Vanilla bean: Scrape the seeds of one vanilla bean into the cream cheese mixture for a more aromatic flavor.
Storage and Reheating
Store leftover cheesecake in an airtight container in the refrigerator for up to 4 days. To freeze, wrap the cooled cheesecake (without powdered sugar) tightly in plastic wrap and then in aluminum foil; freeze for up to 2 months. Thaw overnight in the refrigerator before serving. To reheat, place individual slices on a baking sheet and warm in a 300°F (150°C) oven for 5–10 minutes, or microwave for 15–20 seconds. Note that reheating will make the texture softer and more soufflé-like, which is delicious but different from the chilled version.
Frequently Asked Questions
Why did my cheesecake deflate after baking? The most common cause is underbaking — the center wasn’t set enough. It can also happen if you open the oven door during baking or if you cool it too quickly. Always follow the cooling steps: oven off, door ajar, then room temperature, then fridge.
Can I use all-purpose flour instead of cake flour? Yes, but the texture will be slightly denser. To mimic cake flour, replace 2 tablespoons of all-purpose flour with 2 tablespoons of cornstarch per cup.
Why did my meringue deflate when I folded it in? Your egg whites may have been overbeaten (dry and grainy) or underbeaten (soft peaks). Also, folding too aggressively or in too many strokes will knock out the air. Be gentle and stop as soon as the batter is uniform.
Can I make this without a springform pan? Yes, you can use a regular 9-inch cake pan lined with parchment paper. To remove the cake easily, line the bottom and sides with parchment strips that extend above the rim. Just make sure the pan is at least 3 inches deep, and you’ll need to carefully invert or lift the cake out.
How do I know when it’s done? The edges should be set and the top golden, but the center should still jiggle slightly when you gently shake the pan. A toothpick inserted near the center should come out with a few moist crumbs, not wet batter.
Can I use a hand mixer instead of a stand mixer? Absolutely. Just make sure the bowl and beaters are completely clean and free of any grease or yolk, as that will prevent the egg whites from whipping.
