Light and Airy Coconut Cloud Cake
Coconut Cloud Cake is a tender sponge with real coconut woven through every layer, not just a hint of extract. Whipped egg whites make it so light you could eat a second slice without thinking twice. It tastes like the tropics but feels like a bakery treat you can pull off on a weeknight.
The frosting is nothing more than whipped cream enriched with coconut milk powder, so it lands somewhere between mousse and fresh coconut cream. Stacked up and showered with snowy shreds, it looks like a special-occasion cake while being gentle enough for an afternoon snack.
What Makes This Cake Stay So Light
This cake skips butter creaming entirely. Instead, you whip egg whites into a glossy meringue and fold them into a batter built on coconut milk and egg yolks. That airy meringue is what gives the crumb its cloud-like softness without any tricks.
The frosting plays along, too. Heavy cream whipped with a little powdered sugar and coconut milk powder tastes like fresh coconut without thinning out the cream. It swipes on smooth and stays pillowy, never gritty like buttercream. Every forkful melts.
Ingredients
- 2 cups (250 g) all-purpose flour: spooned and leveled, never scooped.
- 2 tsp baking powder
- ½ tsp fine sea salt
- 1 cup (200 g) granulated sugar: divided.
- 4 large eggs, separated: yolks and whites at room temperature for the best rise.
- ⅔ cup (160 ml) full-fat coconut milk: shake the can well before measuring.
- ¼ cup (60 ml) melted unsalted butter: cooled slightly; coconut oil works too.
- 2 tsp vanilla extract
- ½ tsp coconut extract: optional, but it deepens the tropical notes.
- ¼ tsp cream of tartar: helps the egg whites hold their gloss.
For the frosting
- 1 cup (240 ml) heavy whipping cream: straight from the fridge.
- 3 tbsp powdered sugar: adjust to your sweet tooth.
- 2 tbsp coconut milk powder: found in the baking aisle or Asian grocer; it packs intense coconut without watering down the cream.
- ¼ cup (20 g) unsweetened shredded coconut: for the top, toasted if you like a little crunch.
Variations / Substitutions
- Make it gluten-free: swap in a good cup-for-cup gluten-free flour blend. The crumb stays tender.
- Dairy-free frosting: use chilled full-fat coconut cream instead of heavy cream. Refrigerate the can overnight and scoop off the solid cream, leaving the watery part behind.
- Extra tang: add the finely grated zest of 1 lime to the frosting for a lime-coconut duo.
- Cake filling: spread a thin layer of mango or passion fruit curd between the layers before the cream.

How to Make Coconut Cloud Cake
Step 1: Whisk the Dry and Wet Mixtures
In a medium bowl, whisk the 2 cups flour, baking powder, and salt until evenly mixed. In a larger bowl, beat the egg yolks, ½ cup of the sugar (reserve the remaining sugar for the whites), coconut milk, melted butter, vanilla, and coconut extract until smooth and a shade paler, about 1 minute.
The yolk mixture will look thin at first but turns a soft yellow as the sugar dissolves. Don’t skip the full minute of whisking; it helps the sugar start to dissolve so you don’t feel grit later.
Step 2: Whip the Egg Whites
Pour the egg whites into a completely clean, grease-free bowl and add the cream of tartar. Beat on medium speed until they turn foamy, about 1 minute. With the mixer running, rain in the reserved ½ cup of sugar a tablespoon at a time, then crank the speed to high. Keep whipping until the whites hold stiff, glossy peaks that stand straight up, 3 to 4 minutes total.
Rub a dab between your fingers. If it feels smooth and marshmallow-light, you are there. Any graininess means the sugar hasn’t fully dissolved; beat a bit longer, then test again.
Step 3: Fold the Batter Together
Add the flour mixture to the yolk bowl all at once and stir until almost no dry streaks remain, about 10 seconds. Scoop a heaping spatula of whipped whites onto the batter and gently cut through the center with a large spatula, scraping up from the bottom and turning the bowl a quarter turn each time. Fold until the mixture is evenly pale with no pockets of white, about 30 seconds.
The batter should look airy and thick, like coconut mousse. It’s okay if a few tiny white flecks hide in the batter; overmixing knocks out the air you just worked in, so stop sooner rather than later.
Step 4: Bake the Cake Layers
Preheat the oven to 350°F (180°C) with a rack in the middle. Grease two 8-inch round cake pans and line the bottoms with parchment circles. Divide the batter evenly between the pans and smooth the tops with an offset spatula. Give each pan a gentle tap on the counter to pop any large air bubbles. Bake for 25 to 30 minutes, until the tops are lightly golden and a toothpick inserted in the center comes out clean.
The cakes will feel springy when you press the middle, and the edges will pull slightly away from the sides of the pans. Cool them in the pans on a wire rack for 10 minutes, then turn them out and let them cool completely before you even think about frosting.
Step 5: Frost and Slice the Cake
Chill a mixing bowl and the beaters for 5 minutes, then whip the cold heavy cream, powdered sugar, and coconut milk powder on medium speed until it holds soft to medium peaks, 2 to 3 minutes. Place one cooled cake layer on a serving plate, pile on a generous swoop of the coconut cream, and spread it to the edges. Set the second layer on top and frost the top and sides; a semi-naked look with thin, swirly sides is pretty here. Scatter the shredded coconut over the top and gently press some onto the sides if you like.
Run a serrated knife through the cake using a gentle sawing motion, wiping the blade between slices. Each cut reveals ribbons of white cake and creamy layers. Serve right away or pop it in the fridge for 10 minutes to let the cream set a little firmer.
Tips for a Fluffy Coconut Crumb
- Room temperature eggs are not a suggestion. Cold whites don’t whip to the same lofty volume, so pull the eggs from the fridge 30 minutes before you start.
- Don’t open the oven door in the first 20 minutes of baking. A rush of cool air can cause the delicate batter to sink.
- Use full-fat canned coconut milk. Light versions contain more water and can thin the batter, leaving the cake a little dry.
- Toast the shredded coconut for the garnish. Spread it on a sheet pan and bake at 325°F for 5 to 8 minutes, shaking once, until golden. It adds a warm nuttiness that plays against the creamy frosting.
- No coconut milk powder?: Use 2 tablespoons of cream of coconut (the sweetened, syrup-like kind) and reduce the powdered sugar in the frosting to 1 tablespoon. The cream will still whip up beautifully.
Bake times by pan size:
| Pan Size | Bake Time |
|---|---|
| Two 8-inch rounds | 25–30 mins |
| Two 9-inch rounds | 22–25 mins |
| 12-cup cupcake pan | 18–20 mins |
Storing Leftover Cake
Cover the frosted cake loosely with plastic wrap or a cake dome and refrigerate for up to 3 days. The cream stays soft straight from the fridge, though the cake firms up gently. Let it sit on the counter for 10 minutes before serving if you want a more tender bite.
What to Serve With Coconut Cloud Cake
Fresh mango slices or a pile of ripe berries cut through the richness with a little tart brightness. A cold glass of iced jasmine tea or a mug of dark roast coffee also works, its bitterness balancing the sweet cream and coconut.
Frequently Asked Questions
Why did my cake sink in the middle after baking?
The most common culprit is under-baking—the structure wasn’t set. Check with a toothpick, not just the clock, and make sure it comes out clean. Slamming the oven door while the cake bakes can also jolt the air out.
Can I bake this as a single 9×13 sheet cake?
Yes. Grease a 9×13 pan and bake at the same temperature for 28 to 32 minutes. Keep an eye on it; the thinner layer bakes faster. Frost it right in the pan and cut into squares.
The cake turned out dense and gummy. What went wrong?
Likely the folding step was too heavy-handed. Use the lightest touch you can, just until the batter looks uniform, and don’t stir once that happens. Overmixing the flour into the yolk mixture can also chew up the gluten and weigh things down.
Is the coconut extract necessary?
It is not essential, but it amplifies the flavor in a way coconut milk alone cannot. If you leave it out, the cake will still taste lightly of coconut. Another option: add 2 teaspoons of dark rum for a subtle Caribbean note.
