Cloud Cake
Cloud cake is a light, egg-foam-based cake built by folding a stiff meringue into a thin batter, then baking it slowly in a water bath so it puffs without drying out. The result is a cake that trembles when nudged, tears in soft, spongy shreds rather than crumbs, and tastes faintly of egg and vanilla rather than butter. Most versions found online are a Japanese-influenced soufflé style, sometimes with a little cream cheese folded in for tang, though a simpler egg-only version (closer to the Italian 'nuvola' cake) skips the cheese entirely.
Varieties
The Japanese soufflé version usually includes cream cheese and has a tangier, denser crumb, while the Italian 'nuvola' (cloud) cake is closer to a plain egg-white sponge with no cheese at all, relying only on whipped whites and a touch of cornstarch for its lift.
Buying tips
If buying instead of baking, choose a cake that feels surprisingly light for its size and shows a fine, even network of tiny holes when sliced. Avoid ones with a wet, gummy-looking bottom layer, a sign the water bath ran too hot or too long.
Substitutes
Angel food cake — 1:1 by slice
Also built on whipped egg whites, but baked dry-heat instead of a water bath, so it's drier and springier with none of cloud cake's jiggle.
Chiffon cake — 1:1 by slice
Uses oil and whipped egg whites together, so it's sturdier and holds a frosting better, but loses the barely-there texture cloud cake is known for.
Japanese soufflé cheesecake — 1:1 by slice
The cream-cheese-forward cousin of cloud cake. Denser and tangier, but shares the same water-bath jiggle and delicate crumb.
Classic sponge cake (genoise) — 1:1 by slice
Whipped whole eggs instead of separated whites give it more structure and a slightly eggier flavor, with less lift and no jiggle.
Tres leches cake — not a clean swap
Soaked in sweetened milk after baking, so it's wet and dense rather than airy. Only reach for this if the goal is richness, not lightness.
Storage
Cloud cake keeps for 2 to 3 days refrigerated in an airtight container, since the loose egg-foam structure dries out and deflates quickly at room temperature. Let refrigerated slices sit out for 10 to 15 minutes before serving to soften slightly. It freezes reasonably well wrapped tightly in plastic and foil for up to a month, though thawed texture is a touch denser than fresh.
How to use
Serve plain or with a dusting of powdered sugar, fresh berries, or a light whipped cream. Its mild flavor and soft texture also make it a good base for trifles or layered with fruit compote, since it soaks up syrup or juice without turning gummy the way a denser butter cake would.
What it pairs with
Pairs well with fresh strawberries, a light matcha or black tea, or a thin fruit glaze. Rich sauces or heavy frostings tend to overwhelm its subtle flavor and delicate texture.
Nutrition
Cloud cake gets most of its calories from eggs and sugar rather than butter or oil, so a slice tends to run lower in fat than a traditional layer cake, though cream-cheese versions add back some fat and protein.
FAQ
Why does cloud cake jiggle?
The whipped egg whites trap air into a fine, stable foam, and baking it gently in a water bath sets that foam without fully drying it out, leaving a loose gel-like structure that wobbles when the cake is moved.
Why did the cake sink in the middle after baking?
This usually means the egg whites were underwhipped or overmixed into the batter, deflating the foam, or the cake was pulled from the oven before the center fully set and collapsed as it cooled.
Is cloud cake the same as angel food cake?
No. Both rely on whipped egg whites, but angel food cake bakes dry in a tube pan and comes out springy and dry-textured, while cloud cake bakes in a water bath and stays moist, dense-feeling, and jiggly.
Can cloud cake be made without a water bath?
Not successfully. Baking it directly in dry oven heat causes the top to brown and crack before the center sets, and the cake dries out instead of staying soft and trembly.
