Japanese Milk Cake

This Japanese milk cake is soft, fluffy and light as a cloud. It is not overly sweet, just delicately milky with a hint of vanilla, which makes it perfect with a cup of tea or coffee.

The secret is whipping the egg whites into a glossy meringue and baking the cake gently in a water bath. The result is a tender, jiggly-soft crumb that melts in your mouth.

Ingredients

• ¼ cup (4 tablespoons) unsalted butter
• ¾ cup cake flour, sifted
• 2 tablespoons cornstarch
• ⅓ cup plus 2 tablespoons sugar, divided
• 1 teaspoon vanilla extract

How to Make Japanese Milk Cake

1. Prepare. Heat the oven to 320°F (160°C). Line an 8-inch round pan with parchment and wrap the outside with foil.
2. Warm milk and butter. Heat the milk and butter until the butter melts. Whisk in the flour and cornstarch until smooth.
3. Add yolks. Whisk in the egg yolks, vanilla and salt to make a silky batter.
4. Whip the meringue. Beat the egg whites with lemon juice until foamy, then gradually add the sugar and whip to soft-firm peaks.
5. Fold. Fold the meringue into the batter in three additions, gently, until no white streaks remain.
6. Bake in a water bath. Pour into the pan, tap to release bubbles and place in a larger tray with 1 inch of hot water. Bake for about 60 minutes until golden and springy.
7. Cool. Leave in the turned-off oven with the door slightly open for 10 minutes, then cool completely and dust with powdered sugar.

Tips for the Best Results

• Do not overwhip the meringue; soft-firm peaks give a smoother cake.
• Fold with a spatula using big, gentle strokes.
• Let the cake cool slowly to avoid sinking.

Variations

• Matcha: Replace 1 tablespoon of flour with matcha powder.
• Chocolate: Replace 2 tablespoons of flour with cocoa powder.
• Milk glaze: Brush the top with sweetened condensed milk while warm.

What to Serve With It

Serve plain with tea, or top with whipped cream and fresh strawberries for a special dessert.

Storage and Reheating

Keep covered at room temperature for 1 day or refrigerate for up to 4 days. Let it come to room temperature before serving for the softest texture.

FAQs

Why did my cake crack?

The oven was too hot. Bake low and use a water bath.

Why did it shrink?

Sudden temperature changes cause shrinking. Cool it gradually in the oven.

Can I make it without a mixer?

Yes, but whipping the whites by hand takes patience and a large whisk.
