Quick answer: to stop whipped cream from weeping and deflating, whip cold heavy cream with a stabilizer: powdered sugar, gelatin, mascarpone, instant pudding mix or cornstarch. Stabilized whipped cream holds piped shapes and keeps longer in the fridge.
Start with the right cream
Use cold heavy cream with at least 36% milkfat for the most stable result; see heavy cream vs whipping cream. Chill the bowl and whisk too.
1. Powdered sugar
Whip 1 cup of heavy cream with 2–3 tablespoons of powdered sugar. U.S. powdered sugar usually contains a little cornstarch, which gives a light stabilizing effect. Best for toppings that will be eaten the same day.
2. Gelatin
Sprinkle 1 teaspoon of unflavored gelatin over 4 teaspoons of cold water, let it bloom for 5 minutes, then warm gently until clear. Cool slightly and drizzle it into 1 cup of cream once soft peaks form, then whip to firm peaks. This is the firmest option for piping and frosting.
3. Mascarpone or cream cheese
Beat ¼ to ½ cup of softened mascarpone until smooth, then add 1 cup of cold heavy cream and the sugar and whip together. Gives a rich, sturdy cream for cakes and fillings.
4. Instant pudding mix
Whip 1 cup of heavy cream with 1–2 tablespoons of instant vanilla pudding mix. It thickens quickly and adds flavor, so reduce any other sugar.
5. Cornstarch
Whisk 1 tablespoon of cornstarch with the powdered sugar before adding it to 1 cup of cream. A good choice when you do not have gelatin.
Whipped cream frosting for cakes
For frosting a cake, use the gelatin or mascarpone method above so the cream holds its shape at room temperature for serving. Chill the cake layers first, whip the stabilized cream to firm peaks, frost thinly, then refrigerate the finished cake until shortly before serving.
Using a whipped cream dispenser instead
A sealed whipped cream dispenser dispenses fresh cream on demand and keeps it chilled under nitrous oxide, so it often does not need stabilizing. See how long whipped cream lasts.
Frequently asked questions
What is the easiest way to stabilize whipped cream?
Whip it with powdered sugar, which in the U.S. usually contains cornstarch, or fold in a few spoonfuls of mascarpone. Both help it hold its shape without any cooking.
How long does stabilized whipped cream last?
It holds its shape noticeably longer than plain whipped cream, typically up to a few days covered in the fridge. Use your nose and eyes: discard it if it smells sour or separates.
Can I put stabilizers in a whipped cream dispenser?
Sugar and fully dissolved flavorings are fine. Avoid gelatin and thick add-ins in a dispenser, because they can set or clog the valve. Cream from a sealed dispenser is dispensed fresh, so it usually does not need stabilizing.
