Cloud cake is an ultra-light, airy dessert that quite literally feels like eating a sweet cloud. Unlike dense butter cakes or rich cheesecakes, cloud cake focuses on whipped egg whites for structure, creating a soft, melt-in-your-mouth texture. It’s often compared to Japanese soufflé cheesecake, sponge cake, or angel food cake—but it stands in a category of its own thanks to its delicate crumb and slightly jiggly center.

One of the most famous modern versions is inspired by the Japanese cotton cheesecake popularized by bakeries in cities like Osaka and later made globally famous by stores such as Uncle Tetsu. However, today we’ll focus on a classic vanilla cloud cake that you can easily make at home.

This recipe yields a tall, soft, beautifully risen cake that serves 8–10 people.

☁️ Classic Vanilla Cloud Cake Recie

⏱ Time Required

• Prep Time: 25 minutes
• Bake Time: 50–60 minutes
• Cooling Time: 1 hour

🍰 Equipment Needed

• 8-inch (20 cm) round cake pan
• Parchment paper
• Electric hand mixer or stand mixer
• Mixing bowls (one large, one medium)
• Rubber spatula
• Fine sieve (optional but recommended)

🧁 Ingredients

For the Cake:

• 4 large eggs (room temperature, separated)
• ½ cup (100g) granulated sugar, divided
• ½ cup (120ml) whole milk (room temperature)
• ¼ cup (60ml) neutral oil (vegetable or sunflower)
• ¾ cup (90g) cake flour (or all-purpose flour sifted twice)
• 1 teaspoon vanilla extract
• ½ teaspoon cream of tartar (or 1 teaspoon lemon juice)
• Pinch of salt

Optional Toppings:

• Powdered sugar
• Fresh berries
• Whipped cream
• Lemon zest

👩‍🍳 Step-by-Step Instructions

Step 1: Prepare the Pan

1. Preheat your oven to 325°F (160°C).
2. Line the bottom of your cake pan with parchment paper.
3. Lightly grease the sides.
4. Wrap the outside of the pan with foil if you plan to bake it in a water bath (recommended for extra softness).

The water bath helps regulate heat and prevents cracking, giving you that signature cloud-like texture

Step 2: Separate the Eggs

Carefully separate the egg whites from the yolks.

• Place the whites in a clean, grease-free bowl.
• Put the yolks in a separate bowl.

Tip: Even a tiny bit of yolk in the whites can prevent pr

1. Add milk, oil, and vanilla extract to the egg yolks.
2. Whisk until smooth and pale.
3. Sift in the flour and salt.
4. Gently mix until just combined.

Do not overmix. The batter should be smooth and slightly thick but pourable.

Step 4: Whip the Egg Whites (The Key to Cloud Texture)

1. Begin beating the egg whites on medium speed.
2. Once foamy, add cream of tartar.
3. Gradually add sugar (about 1 tablespoon at a time).
4. Increase speed and whip until medium-stiff peaks form.

You’re looking for peaks that stand but slightly curl at the tip. Overwhipping can make the cake collapse

Step 5: Fold theThis step determines whether your cake stays airy.

Use slow, circular motions. Rotate the bowl while lifting the batter from bottom to top. Do not

Step 6: Bake

Option A: Water Bath (Recommended)

1. Pour batter into the prepared pan.
2. Tap lightly to remove large air bubbles.
3. Place the pan into a larger baking dish.
4. Pour hot water around the cake pan until halfway up the sides.
5. Bake for 50–60 minutes.

Option B: Without Water Bath

Bake directly on the oven rack for 40–50 minutes, but watch carefully for cracks.

The cake is done w

Step 7: Cooling

1. Turn off oven.
2. Leave cake inside with door slightly open for 15 minutes.
3. Remove and cool completely before unmolding.

Sudden temperature changes cause collapse, so patience is important.

🎂 Serving Ideas

Cloud cake pairs beautifully with:

• Lightly sweetened whipped cream

• Matcha dusting

For a Japanese-style presentation reminiscent of specialty shops in Kyoto, serve the cake simply dusted with powdered sugar and cut into tall, clean slices.

💡 Expert Tips for the Perfect Cloud Cake

1. Room temperature eggs whip better.
2. Use cake flour for lighter texture.
3. Don’t rush folding.
4. Use a scale for accuracy.
5. Bake on the lower rack to avoid over-browning.
6. Avoid convection mode if possible.

☁️ Why Cloud Cake Works (The Science)

Cloud cake relies on whipped egg whites (a foam structure). When beaten, proteins in egg whites trap air. During baking:

• Air expands
• Proteins set
• Moisture turns into steam
• Structure stabilizes

The water bath keeps temperature gentle, preventing rapid expansion that causes cracks.

Unlike butter cakes, cloud cake contains little fat. Its structure comes primarily from egg foam rather than gluten development, which explains its airy feel.
