Japanese Cheesecake Ottawa Recipe: Cotton Soft

Japanese cheesecake, also known as cotton cheesecake or soufflé cheesecake, is a delicately jiggly, cloud-like dessert that is immensely popular in Ottawa’s bakeries and home kitchens. Unlike its dense New York cousin, this version relies on a whipped meringue folded into a cream cheese base, creating an airy texture that melts in your mouth. This recipe is designed for home ovens, using a water bath to ensure a smooth, crack-free top and that signature wobble.

Ingredients

8 oz (226 g) cream cheese, at room temperature
1/2 cup (120 ml) whole milk
1/4 cup (57 g) unsalted butter, cubed
6 large eggs, separated (yolks in one bowl, whites in another)
1/2 cup (100 g) granulated sugar, divided
1/4 cup (32 g) all-purpose flour
2 tablespoons (16 g) cornstarch
1 teaspoon vanilla extract
1/4 teaspoon cream of tartar
Pinch of salt

Instructions

Prep the pan and oven: Preheat your oven to 325°F (165°C). Grease a 9-inch (23 cm) round springform pan with butter and line the bottom and sides with parchment paper. If your springform pan tends to leak, wrap the outside tightly with two layers of aluminum foil to keep water out during the water bath.
Make the cream cheese base: In a large heatproof bowl set over a pot of simmering water (a double boiler), combine the cream cheese, milk, and butter. Stir frequently until the mixture is completely smooth and no lumps remain. Remove from heat and let it cool slightly for 5 minutes.
Add yolks and dry ingredients: Whisk the egg yolks into the cream cheese mixture one at a time, mixing well after each addition. Add the vanilla extract. Sift the flour, cornstarch, and salt over the mixture and whisk gently until just combined. The batter should be smooth and thick. Set aside.
Whip the meringue: In a clean, dry bowl (preferably metal or glass), beat the egg whites with an electric mixer on medium speed until frothy. Add the cream of tartar. Continue beating, gradually adding the remaining 1/4 cup (50 g) of sugar in a slow stream. Increase the speed to high and beat until stiff peaks form. The meringue should be glossy and hold a firm peak when the whisk is lifted, but not dry or clumpy.
Fold the batter: Add one-third of the meringue to the cream cheese mixture and whisk gently to lighten the batter. Then, use a rubber spatula to fold in the remaining meringue in two additions. Fold with a sweeping motion from the bottom up, rotating the bowl, until no white streaks remain. Be careful not to overmix, as this will deflate the air and make the cake dense.
Bake in a water bath: Pour the batter into the prepared springform pan and smooth the top with a spatula. Place the pan into a larger roasting pan or baking dish. Place the roasting pan on the oven rack, then carefully pour hot (not boiling) water into the roasting pan until it reaches about 1 inch (2.5 cm) up the sides of the springform pan.
Bake low and slow: Bake at 325°F (165°C) for 20 minutes. Then, without opening the oven door, reduce the temperature to 300°F (150°C) and bake for another 50 to 55 minutes. The cake is done when the top is golden brown and the center is just set—it should jiggle slightly when the pan is gently shaken. A skewer inserted into the center should come out mostly clean, with a few moist crumbs. The internal temperature of the cake should reach 160°F (71°C) for food safety, as this is an egg dish.
Cool in the oven: Turn off the oven and leave the cake inside with the door slightly ajar (prop it open with a wooden spoon) for 1 hour. This gradual cooling prevents the cake from collapsing and cracking.
Chill completely: Remove the pan from the water bath and take off the aluminum foil. Let the cake cool to room temperature on a wire rack for about 30 minutes, then cover the pan with plastic wrap and refrigerate for at least 3 hours, or preferably overnight. This step is essential for the texture to set properly.

Tips

Room temperature ingredients: Cold cream cheese and eggs will create a lumpy batter and a meringue that won’t whip as well. Set everything out 30-45 minutes before starting.
Don’t skip the water bath: The steam from the hot water keeps the oven humid, which prevents the top from drying out and cracking. If you don’t have a roasting pan, use any large oven-safe dish.
Fold, don’t stir: When combining the meringue, use a gentle folding motion. Overmixing deflates the batter and results in a dense, rubbery cake.
Substitutions: For a gluten-free version, replace both the all-purpose flour and cornstarch with 1/4 cup (32 g) of gluten-free all-purpose flour blend. The texture will be slightly less tender but still delicious. For a richer flavor, substitute half the milk with heavy cream.

Serving Suggestions

Serve this cheesecake chilled, straight from the refrigerator. It is delicious on its own, but a light dusting of powdered sugar and a few fresh berries (strawberries or raspberries) add a nice contrast. In Ottawa, it’s often enjoyed with a cup of green tea or a light coffee. You can also drizzle it with a simple fruit coulis or a spoonful of sweetened whipped cream.

Variations

For a matcha Japanese cheesecake, sift 1 tablespoon (8 g) of matcha powder with the flour and cornstarch. For a lemon version, add the zest of one lemon to the cream cheese mixture and replace the vanilla with lemon extract. A chocolate version can be made by replacing 2 tablespoons (16 g) of the flour with 2 tablespoons (16 g) of unsweetened cocoa powder.

Storage and Reheating

Store the cheesecake in an airtight container in the refrigerator for up to 4 days. This cake is best served cold and does not need reheating. If you prefer a slightly warm center, you can microwave a single slice for 10-15 seconds, but be aware it will lose some of its delicate structure. To freeze, wrap the whole cake (or individual slices) tightly in plastic wrap and then in aluminum foil for up to 1 month. Thaw overnight in the refrigerator before serving.

Frequently Asked Questions

Why did my cheesecake crack on top? Cracks are usually caused by a sudden temperature change or an oven that’s too hot. Make sure you are using a water bath, cooling the cake in the oven with the door ajar, and not opening the oven door during baking.

Why is my cheesecake dense and not fluffy? This is almost always due to overmixing the batter when folding in the meringue, or the meringue being under-whipped. Ensure your egg whites reach stiff peaks, and fold gently but thoroughly until just combined.

Can I use a regular cake pan instead of a springform pan? Yes, but you’ll need to line it with parchment paper that extends above the rim so you can lift the cake out. A springform pan is easier because it allows you to release the sides without flipping the cake.

My cheesecake is too brown on top. What went wrong? Your oven might be running hot, or the cake was positioned too close to the top heating element. Place the roasting pan on the lower-middle rack. If the top is browning too quickly, you can tent it loosely with aluminum foil for the last 20 minutes of baking.

Do I have to refrigerate it overnight? While you can serve it after just 3 hours of chilling, overnight refrigeration allows the flavors to meld and the texture to become perfectly creamy and stable. It’s highly recommended for the best result.

Can I double this recipe? Yes, you can double the ingredients, but you will need to use two separate 9-inch pans. Bake them both in the same water bath, making sure the roasting pan is large enough to hold both without them touching.
