Medium Japanese Cheesecake Recipe (Cotton Soft)

Medium Japanese cheesecake, also known as cotton cheesecake, is a delicate hybrid between a classic American cheesecake and a sponge cake. It’s made with cream cheese, eggs, sugar, and a small amount of flour, then baked in a water bath to achieve its signature jiggle and cloud-like crumb. This recipe is designed to give you that perfect “medium� texture—tall enough to slice cleanly, but soft enough to melt on your tongue.

Ingredients

8 oz (226 g) cream cheese, at room temperature
1/2 cup (120 ml) whole milk
1/4 cup (57 g) unsalted butter, at room temperature
6 large eggs, separated (yolks in one bowl, whites in another)
1/2 cup (100 g) granulated sugar, divided (2 tbsp for yolks, 6 tbsp for whites)
1/4 cup (30 g) cake flour, sifted
2 tbsp (16 g) cornstarch, sifted
1 tsp lemon juice (optional, for flavor)
1/4 tsp cream of tartar (or 1/2 tsp lemon juice for stabilizing egg whites)
Pinch of salt

Instructions

Prep the pan and oven: Preheat your oven to 325°F (163°C). Grease a 9-inch (23 cm) round springform pan with butter, then line the bottom and sides 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.
Make the cream cheese base: In a large bowl, beat the cream cheese and butter together until smooth and creamy, about 2 minutes. Add the milk and mix until combined. It’s okay if the mixture looks slightly curdled; it will smooth out later.
Add egg yolks: Beat in the egg yolks one at a time, mixing well after each addition. Add 2 tablespoons of the sugar, the lemon juice (if using), and the salt. Mix until smooth.
Add dry ingredients: Gently fold in the sifted cake flour and cornstarch with a spatula until just combined. Do not overmix; set aside.
Whip the egg whites: In a clean, dry bowl, beat the egg whites with an electric mixer on medium speed until foamy. Add the cream of tartar (or lemon juice) and continue beating. Gradually add the remaining 6 tablespoons of sugar, 1 tablespoon at a time, while beating. Increase speed to high and beat until stiff peaks form—when you lift the beater, the whites should stand straight up but still look glossy.
Fold the meringue: Add one-third of the egg whites to the cream cheese mixture and fold gently with a spatula to lighten. Then add the remaining whites in two batches, folding slowly and carefully until no white streaks remain. The batter should be airy but smooth.
Fill the pan: Pour the batter into the prepared springform pan. Tap the pan on the counter a few times to release any large air bubbles.
Water bath: Place the springform pan in a larger roasting pan. Pour hot (not boiling) water into the roasting pan until it reaches about halfway up the sides of the springform pan. The water should be about 140°F (60°C)—hot to the touch but not bubbling.
Bake: Bake at 325°F (163°C) for 20 minutes. Then reduce the oven temperature to 300°F (149°C) and continue baking for 50–55 minutes, until the top is golden brown and the center is just set—it should wobble slightly when gently shaken. A toothpick inserted into the center should come out clean or with a few moist crumbs.
Cool in the oven: Turn off the oven and leave the cheesecake inside with the door slightly ajar (use a wooden spoon to keep it open) for 1 hour. This gradual cooling prevents the cake from collapsing.
Chill: Remove the cheesecake from the water bath, take off the aluminum foil, and let it cool to room temperature on a wire rack. Then cover the pan with plastic wrap and refrigerate for at least 4 hours, preferably overnight. This step is essential for the texture to set properly.
Serve: Run a knife around the edge of the pan, release the springform, and carefully peel off the parchment. Slice with a sharp, non-serrated knife, wiping the blade between cuts for clean slices.

Tips

Room temperature ingredients are non-negotiable: Cream cheese, butter, and eggs must be at room temperature to avoid lumps and to ensure a smooth batter. Cold eggs will make the mixture seize.
Don’t skip the water bath: The steam from the hot water keeps the oven moist and the cheesecake from cracking. If you skip it, the top will brown too quickly and the center will be dry.
Fold, don’t stir: Overmixing deflates the egg whites, resulting in a dense, rubbery cake. Use a spatula and cut through the center, then scrape the sides—just until no streaks remain.
Cool gradually: Sudden temperature changes cause the cake to sink. Always cool in the oven with the door ajar, then at room temperature, then in the fridge.

Serving Suggestions

Serve medium Japanese cheesecake slightly chilled or at room temperature. It’s wonderful on its own, but you can dust it with powdered sugar, drizzle with honey, or top with fresh berries and a dollop of whipped cream. For a more decadent touch, serve with a warm fruit compote or a spoonful of lemon curd. The mild flavor pairs well with green tea, coffee, or a glass of cold milk.

Variations

Matcha: Add 1 tablespoon of matcha powder to the dry ingredients for a subtle earthy flavor and a beautiful green hue.
Lemon: Increase the lemon juice to 2 tablespoons and add 1 teaspoon of lemon zest to the cream cheese mixture for a brighter, citrusy version.
Chocolate: Replace 1 tablespoon of cake flour with 1 tablespoon of unsweetened cocoa powder and add 2 oz (57 g) of melted dark chocolate to the cream cheese mixture.
Vanilla bean: Scrape the seeds of half a 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 whole cake (or individual slices) tightly in plastic wrap, then in aluminum foil, and freeze for up to 1 month. Thaw in the refrigerator overnight before serving. To reheat, place slices in a 300°F (149°C) oven for 5–8 minutes until just warm—this will make them extra soft, but note that reheating may cause the cake to lose some of its delicate structure. It’s best enjoyed cold or at room temperature.

Frequently Asked Questions

Why did my cheesecake crack on top? Cracks usually happen because the oven is too hot, the batter was overmixed, or the cake cooled too quickly. Make sure to use a water bath, bake at the lower temperature as instructed, and always cool in the oven with the door ajar.

Can I use a regular round cake pan instead of a springform pan? Yes, but line the bottom with parchment paper and leave a “collar� of parchment extending above the rim to help lift the cake out. You’ll need to carefully invert it to remove, which is easier if you let it cool completely and run a knife around the edges.

My egg whites won’t stiffen—what’s wrong? Make sure the bowl and beaters are completely clean and free of any grease or yolk. Even a tiny amount of fat can prevent egg whites from whipping. Also, use room-temperature eggs; cold whites are harder to whip.

Can I reduce the sugar? You can reduce the total sugar by up to 2 tablespoons, but the meringue may be less stable and the cake will be less sweet. Don’t reduce more than that or the texture will suffer.

Why is my cake dense and rubbery? This is usually caused by overmixing the batter after adding the egg whites, or by using too much flour. Be gentle when folding, and measure your flour correctly by spooning it into the cup and leveling off.

Do I need to use cake flour? Cake flour gives a lighter crumb due to its lower protein content. If you don’t have it, you can substitute all-purpose flour, but the texture may be slightly denser. To make a quick substitute, remove 2 tablespoons of all-purpose flour and replace with 2 tablespoons of cornstarch.
