Whipped Cream Frosting: How to Get It on a Cake and Keep It There

Buttercream holds up because it’s mostly butter and icing sugar. Whipped cream tastes better and behaves worse — which is why people who try it once often go back.

It doesn’t have to go that way. The recipes are easy to find. What’s harder to find is how to get the stuff onto a cake and keep it standing until someone cuts it.

What makes frosting different from whipped cream

A few things separate the two, and only one of them is the recipe.

It’s stabilised. Plain whipped cream is a foam held up by fat alone, and it starts collapsing as soon as it’s exposed to air and warmth. Frosting has something in it doing structural work. Which stabiliser you use changes how long it holds and how it tastes, and our guide to stabilising whipped cream compares six of them.

It’s whipped stiffer. Cream for a dessert stops at soft peaks. Cream that has to hold a piped edge goes further, to the point where it looks almost too firm in the bowl. That’s the right texture. It’ll loosen slightly as you work with it.

It’s sweeter, though only just. A whipped cream frosting sits somewhere around a tablespoon of icing sugar per cup of cream. That’s a fraction of what goes into buttercream, which is the entire reason people want it.

How much you need

Cream roughly doubles in volume when you whip it, so work out the finished amount you need and halve it to get the carton size.

As a starting point, 600ml of liquid cream will fill and coat a 20cm two-layer cake with a bit spare for piping. A single-layer cake or a tray of cupcakes needs around half that. Scale from there, and buy more than the number says, because running out halfway through a crumb coat means starting the coat again with a fresh batch.

Use thickened cream, 35% fat or higher. Pure cream whips softer and won’t hold an edge as long. If your cream isn’t thickening at all, the fat percentage is nearly always the reason, and our guide to cream that won’t whip covers the rest.

Layering without the cake sliding

The classic failure is a two-layer cake where the top layer has quietly skated three centimetres to the left. Whipped cream is slippery in a way buttercream isn’t, and a heavy top layer sitting on a soft filling will move.

What stops it:

• Pipe a ring of firm cream around the edge of the bottom layer and fill inside it. The ring acts as a wall and takes the weight.
• Chill between steps. Fill, then refrigerate until the cream is firm to the touch before the next layer goes on.
• Keep the filling thin. A thick layer of cream in the middle is where the movement comes from.

Cake must be completely cool before any of this — a barely-warm sponge will melt the first thing you put on it.

Crumb coat and finishing

A crumb coat matters more with cream than with buttercream, because cream is thinner and every crumb it picks up shows through white.

Spread a deliberately thin layer over the whole cake, thin enough to see the sponge through it, and chill it until the surface is set. That layer traps the crumbs. The proper coat goes on top and stays clean.

Work with a cold offset spatula and don’t overwork the surface. Whipped cream doesn’t take endless smoothing the way buttercream does; keep pushing it around and it goes grainy under the palette knife.

Piping

Cream pipes well as long as it’s cold and firm, and it stops piping well the moment your hands warm the bag.

Fill the bag half full at most and keep the rest in the fridge. Work in short sessions. If the rosettes start losing their edges, the bag has warmed up, and a few minutes in the fridge brings it back.

Open star tips are the forgiving choice. Fine tips take longer and more squeezing, which means more time with your hands wrapped around the cream.

Where a dispenser fits, and where it doesn’t

Cream from a cream charger is lighter and more aerated than cream beaten in a bowl, which makes it the wrong texture for a crumb coat or a smooth-sided cake. It won’t spread flat and it won’t hold a sharp edge under a scraper. That’s a texture difference, not a stability one: charged cream keeps for days in the bottle, it just doesn’t behave like something you can scrape smooth.

Where it’s genuinely better is piped detail added at the last minute. Rosettes on cupcakes, a border around a base, a swirl on each slice as it’s served. The cream stays under pressure in the fridge until the moment it’s needed, so you’re piping fresh cream onto a cake that was finished hours ago. For decorating, a dispenser does the finishing work and a bowl does the frosting.

How far ahead, and getting it there

A stabilised cream cake will sit in the fridge overnight and be fine. Uncovered is better than wrapped, since plastic pressed against the surface takes the finish with it when you pull it off. If you need to cover it, use a cake box or an upturned bowl that doesn’t touch the cream.

Out of the fridge you have a couple of hours, not an afternoon. Heat softens the fat holding the structure, and an Australian summer works fast. Keep the cake inside until people are ready for it.

Transporting one is a flat surface and a cold car — the boot on a hot day is the worst place for it. If the drive is long, take the cake plain and pipe it at the other end.

Flavouring it

Vanilla is the default and it’s hard to beat. Cocoa sifted in with the icing sugar makes a chocolate version that pipes the same. Citrus zest works. A spoonful of good jam folded through at the end gives colour and flavour without loosening the structure much.

Anything with alcohol in it needs care, since spirits thin cream fast. We’ve covered the technique in alcohol-infused whipped cream.

Frequently asked questions

What’s the difference between whipped cream and whipped cream frosting?

Frosting is stabilised, whipped stiffer and usually a little sweeter. Plain whipped cream is made to be eaten within the hour. Frosting is made to hold a shape.

Can I turn whipped cream into frosting?

If it’s still soft, yes. Keep whipping and add a stabiliser. If it’s already grainy you’ve gone too far, and folding in a splash of cold cream by hand is the only thing that brings it back.

How much whipped cream do I need to frost a cake?

Start with 500 to 600ml of liquid cream for a 20cm two-layer cake, and around half that for a single layer or a batch of cupcakes. Buy extra.

Will a whipped cream cake survive a birthday party?

Stabilised and kept in the fridge until it’s needed, yes. Sitting on a table in the sun for two hours, no. Bring it out when you’re ready to cut it.

Can you freeze a cake frosted with whipped cream?

You can, though the texture changes on thawing and the surface tends to weep. Freeze the cake layers instead and frost after they’ve come back to room temperature.
