Key Ingredients
Before you begin, gather these carefully measured ingredients to achieve the signature light and fluffy texture Japanese cotton cheesecake is known for:
- 200 g cream cheese – The creamy, slightly tangy foundation of the cupcakes
- 30 ml milk – Adds moisture and smoothness
- 50 g unsalted butter – Creates richness and a tender crumb
- 6 large eggs, separated – Yolks enrich the batter; whites create lift
- 40 g sugar – Sweetens the cream cheese mixture
- 60 g sugar – Whipped into the egg whites for a stable meringue
- 50 g cake flour – Keeps the texture soft and delicate
- 20 g cornstarch – Ensures a fine, airy crumb
- 1 teaspoon vanilla extract – Adds gentle warmth and aroma
- 1/4 teaspoon cream of tartar – Stabilizes the egg whites
- Pinch of salt – Enhances overall flavor
How to Make Fluffy Japanese Cotton Cheesecake Cupcakes
- Prepare the oven
Preheat oven to 160°C (320°F). Line a 12-cup muffin tin with paper liners. Place a shallow roasting pan on the lower rack to prepare for a water bath. - Melt the base
In a heatproof bowl over simmering water, melt the cream cheese, milk, and butter together. Stir until completely smooth, then remove from heat. - Build the batter
Whisk egg yolks into the warm cream cheese mixture one at a time. Add 40 g sugar and mix until smooth. Sift in cake flour, cornstarch, and salt, folding gently. Stir in vanilla extract. - Whip the meringue
In a clean, grease-free bowl, beat egg whites with cream of tartar until foamy. Gradually add 60 g sugar and continue whipping until stiff, glossy peaks form. - Fold carefully
Fold one-third of the meringue into the batter to lighten it. Gently fold in the remaining meringue in two batches, using slow, sweeping motions. - Fill and bake
Divide batter evenly into cupcake liners, filling about two-thirds full. Lightly tap the pan to release air bubbles. Pour hot water into the roasting pan until it reaches halfway up the muffin tin. - Bake gently
Bake for 25–30 minutes, until the tops are lightly golden and the centers are set. - Cool gradually
Turn off the oven and crack the door open slightly. Let cupcakes sit in the water bath for 15 minutes, then remove and cool completely on a wire rack.

Frequently Asked Questions
Why is a water bath necessary?
The water bath provides gentle, even heat and moisture, preventing cracking and collapse while creating a silky texture.
Can I use all-purpose flour instead of cake flour?
Yes. Replace 50 g cake flour with 47 g all-purpose flour plus 3 g cornstarch. Sift well.
Why did my cupcakes deflate?
Overmixing or aggressive folding can knock out air. Fold gently and stop as soon as combined.
Can I make these ahead of time?
Yes. Bake up to one day ahead and store refrigerated until serving.
