Cloud ice is the ultra-fluffy, snow-like shaved ice that melts on your tongue, popular in Korean bingsu shops and Taiwanese dessert cafes. You can make it at home with milk, sweetened condensed milk, and a food processor or shaved ice machine. The secret is freezing a sweetened milk mixture into solid blocks, then shaving or grinding them into feathery ribbons that hold toppings without turning into a soggy puddle.
Why Cloud Ice Feels Different From Regular Shaved Ice
Regular shaved ice starts with plain water frozen into a block, then scraped into crystals. It’s crunchy, melts fast, and pools at the bottom of the bowl. Cloud ice replaces water with a milk-based liquid. The fat and sugar in milk change the way ice crystals form during freezing, producing smaller, more uniform crystals. When you shave or grind those milk-ice blocks, the result is thin, ribbon-like curls that feel creamy rather than icy. They compress softly under a spoon instead of shattering, which is where the “cloud” comparison comes from.
The Basic Recipe
The simplest version uses just two ingredients:
- 1 cup whole milk
- 2 tablespoons sweetened condensed milk
Stir the milk and condensed milk together until fully combined. Pour the mixture into an ice cube tray or a shallow, freezer-safe container. Freeze for at least five hours, or until the blocks are completely solid. If you use a shallow container (like a loaf pan), the thinner slab will freeze faster and shave more evenly.
Once frozen, pop the blocks out and run them through a food processor. Pulse for about 20 seconds until the texture looks smooth and powdery, like fresh snow. If you over-process, the ice will start to melt from the friction and turn slushy, so work quickly. A dedicated shaved ice machine with a freezing drum produces even finer ribbons, but a food processor gets you 90% of the way there.
Variations Worth Trying
The base recipe is a starting point. Swapping in different liquids changes both the flavor and texture of the final product.
For a richer cloud ice, increase the condensed milk to three tablespoons or replace a quarter of the whole milk with heavy cream. The extra fat makes the shavings denser and slower to melt, which gives you more time to eat before everything collapses. For a lighter version, use low-fat milk, though the texture won’t be quite as creamy.
Fruit-flavored cloud ice works well too. Blend half a cup of mango, strawberry, or any soft fruit with the milk mixture before freezing. Coconut milk (full-fat, from a can) creates an especially smooth result because of its high fat content. Matcha powder, cocoa powder, or instant coffee dissolved into the milk base before freezing all produce great results. Just make sure any powder is fully dissolved so you don’t get gritty patches in the finished ice.
Getting the Texture Right
The most common mistake is freezing the mixture too long in too large a container. A massive block of milk ice is difficult to shave evenly, and it warms up on the outside while the center stays rock-hard. Use ice cube trays or small silicone molds so each piece is a manageable size for your food processor.
Temperature matters at every step. Pull the ice blocks out of the freezer and let them sit at room temperature for two to three minutes before processing. This brief temper softens the outer surface just enough for the blade to catch and create fine shavings instead of chunky fragments. If the pieces are too warm and you see liquid pooling in the processor, stop immediately and refreeze for 15 minutes.
Serve cloud ice the moment it’s ready. It loses its fluffy structure within a few minutes at room temperature. Chill your serving bowl in the freezer beforehand to buy yourself extra time.
Equipment Options
A standard food processor is the most accessible tool. It won’t produce the perfectly thin ribbons of a commercial machine, but the texture is still distinctly different from crushed ice. Use the S-blade and pulse in short bursts rather than running continuously.
If you make cloud ice often, a dedicated snow ice machine is a worthwhile upgrade. Commercial models use a freezing drum made of food-grade stainless steel that flash-freezes a thin layer of liquid directly onto the drum surface, then scrapes it off in delicate curls. Home versions of these machines are available for under $200 and produce results much closer to what you’d get at a bingsu shop. The key difference is consistency: a machine produces uniform, paper-thin shavings every time, while a food processor gives you a mix of fine powder and slightly larger pieces.
A high-powered blender can work in a pinch, but it tends to over-process quickly, turning the ice into slush rather than snow. If it’s your only option, use the lowest speed and stop the moment the texture looks right.
Classic Toppings and Combinations
Korean injeolmi bingsu tops the milk snow ice with roasted soybean powder, small pieces of rice cake, and an extra drizzle of condensed milk. The soybean powder sticks to the ice shavings and adds a nutty, toasty flavor that pairs surprisingly well with the sweet milk base.
Fresh fruit is the simplest topping. Mango, strawberries, and kiwi all work well. Cut fruit into small pieces so they nestle into the ice rather than sliding off. A scoop of red bean paste is traditional in both Korean and Taiwanese versions. Mochi pieces, crushed cookies, or a small scoop of ice cream on top are all common additions. For a chocolate version, drizzle melted chocolate or chocolate syrup over cocoa-flavored cloud ice and top with brownie pieces.
The Science Behind Cloud Formation
If you landed here looking for actual cloud ice (the kind that forms in the atmosphere), the process is fascinating but quite different from dessert-making. Real ice crystals form inside clouds when water vapor encounters tiny particles like dust, pollen, or even bacteria. These particles give water molecules a surface to latch onto and begin crystallizing, a process called heterogeneous nucleation. Without those particles, water droplets in clouds can remain liquid even at temperatures well below freezing, sometimes as cold as minus 36°C.
Inside clouds where ice crystals and supercooled water droplets coexist, the ice crystals actually steal moisture from the droplets. Water vapor naturally migrates from the liquid droplets toward the ice crystals because ice has a lower vapor pressure at the same temperature. This is called the Bergeron process, and it’s the main way ice crystals in clouds grow large enough to eventually fall as snow or rain.
You can see a simplified version of this at home with NASA’s cloud-in-a-bottle experiment. Fill a jar with two inches of warm water, drop in a just-extinguished match (the smoke provides particles for condensation), and immediately cover the top with a tray of ice. The warm water vapor rises, hits the cold air near the ice, and condenses on the smoke particles into a visible misty cloud inside the jar. It’s not quite “cloud ice,” but it demonstrates the same principles that create ice crystals thousands of feet above you.
