You just bought a can of Reddi Wip and are wondering if it really needs to go in the fridge before you open it. Or you have leftover Cool Whip from a recipe and are not sure if it goes back in the fridge or the freezer. Does whipped cream need to be refrigerated? The answer is different depending on which product you have.
Does all whipped cream need to be refrigerated?
The short answer: Yes for homemade whipped cream and aerosol cans like Reddi Wip, which must be refrigerated at all times. Cool Whip is the exception: it is a frozen product that lives in the freezer and only moves to the refrigerator when you are ready to use it. All three types follow the standard 2-hour rule: do not leave any whipped product at room temperature for more than 2 hours.

Key Takeaways
- Homemade whipped cream: refrigerate immediately, use within 1 to 2 days
- Aerosol cans (Reddi Wip): refrigerate at all times, even before opening
- Cool Whip: store in the freezer; move to fridge 4 to 5 hours before use
- All types: discard if left at room temperature more than 2 hours
- Store aerosol cans upright; clean nozzle after every use
Does Homemade Whipped Cream Need to Be Refrigerated?
Yes, immediately and continuously. Homemade whipped cream is heavy cream with no preservatives, no stabilizers, and no protective packaging. It is one of the most perishable foods you can make. Left at room temperature, it begins to collapse and weep within an hour or two. The USDA 2-hour rule applies fully: any homemade whipped cream left out more than 2 hours should be discarded.
In the refrigerator, homemade unstabilized whipped cream holds for 1 to 2 days. Adding a stabilizer (unflavored gelatin or cornstarch) before whipping extends that to 3 to 4 days. Store it in an airtight container to prevent it from absorbing refrigerator odors, and keep it toward the back of the fridge on an interior shelf where temperatures are most stable.
Does Reddi Wip Need to Be Refrigerated Before Opening?
Yes. Reddi Wip and other aerosol whipped creams contain real dairy cream, which is perishable regardless of the pressurized packaging. The can must be refrigerated at all times, including before it is opened for the first time. You will find aerosol whipped cream in the refrigerated dairy section of the grocery store, and it belongs in your refrigerator from the moment you bring it home.
The pressurized nitrous oxide propellant inside the can limits oxygen exposure and helps preserve the cream, which is why aerosol whipped cream lasts 2 to 3 months in the fridge. But that protection only works when the can stays cold. Left at room temperature, the cream inside is subject to the same 2-hour perishable food rule as any other dairy product.
Store aerosol cans upright, not on their side. A can stored on its side can result in uneven pressure distribution, causing the propellant and cream to separate and the can to dispense poorly. Keep the can toward the back of the refrigerator on an interior shelf, not in the door where temperatures fluctuate.
Does Cool Whip Need to Be Refrigerated?
Cool Whip is different from the other two products. It is a frozen whipped topping sold in the freezer section of the grocery store, and the freezer is its primary home. It does not belong in the refrigerator long-term. Store it in your freezer until you are ready to use it, then transfer it to the refrigerator for 4 to 5 hours to thaw before serving.
Once thawed, Cool Whip should stay in the refrigerator and be used within 1 to 2 weeks. It should not sit on the counter long-term. While it is more structurally stable than dairy cream at room temperature due to its oil-based emulsion, it is still perishable and the 2-hour rule applies.
Quick Reference: Where Each Type Lives
- Homemade whipped cream: Refrigerator only. Use within 1 to 2 days (3 to 4 if stabilized).
- Reddi Wip (aerosol can): Refrigerator at all times, opened or not. Good for 2 to 3 months.
- Cool Whip (frozen tub): Freezer until needed, then refrigerator. Use within 1 to 2 weeks of thawing.
How to Store Each Type Correctly
Homemade Whipped Cream
- Transfer to an airtight container immediately. Do not leave in the mixing bowl uncovered.
- Store toward the back of the fridge on a middle shelf, away from the door.
- If stabilizing, add 1 teaspoon of gelatin (bloomed in 1 tablespoon cold water, then warmed until dissolved and cooled) per cup of cream before whipping, or 1 tablespoon of cornstarch per cup.
- Do not store on a dessert at room temperature for more than 2 hours. If the dessert will sit out longer, add the whipped cream at serving time or use stabilized whipped cream.
Aerosol Cans (Reddi Wip)
- Refrigerate immediately after purchase. Do not leave on the counter or in a cabinet.
- Store upright, not on the side.
- After every use, rinse the nozzle with warm water and wipe dry. The Reddi Wip label calls this out directly. A clogged or contaminated nozzle is one of the main ways aerosol whipped cream spoils prematurely.
- Keep toward the back of the fridge on an interior shelf, not in the door.
- Do not freeze the can. If you want to freeze some of the contents, dispense dollops onto parchment paper and freeze those instead.

Cool Whip and Frozen Whipped Toppings
- Keep in the freezer until needed. Freezer life is up to 4 months.
- Thaw in the refrigerator, 4 to 5 hours or overnight. Do not thaw on the counter or in the microwave; both methods damage the emulsion and result in a watery, separated texture.
- Once thawed, keep refrigerated and use within 1 to 2 weeks.
- Kraft’s official guidance is not to refreeze Cool Whip after thawing. If the Cool Whip was thawed in the refrigerator and has not been left at room temperature, a single refreeze may not cause significant quality loss in practice, but the manufacturer does not endorse it.
What About Whipped Cream on a Dessert That Is Sitting Out?
The 2-hour rule applies to the dessert as a whole once it has whipped cream on it. A pie topped with homemade whipped cream and left on the table at a party should be returned to the refrigerator or discarded after 2 hours. Cool Whip holds its shape much longer at room temperature than fresh cream does, which is one reason it is often preferred for outdoor events, but it still falls under the 2-hour perishable food guideline regardless of how it looks.
Recipes That Use Whipped Cream
If you have homemade whipped cream to use before it turns, put it to work. The Scottish cranachan is built around freshly whipped cream layered with raspberries, toasted oats, and whisky. The creamy caramel flan is traditionally served with a dollop alongside each slice. Both are worth making specifically to use up cream before it goes.

FAQ: Can You Leave Reddi Wip Unrefrigerated After Opening?No. Once the can is at room temperature, the cream inside is in the temperature danger zone just like any other dairy product. Brief exposure during use (setting it on the counter while topping a dessert) is fine. But leaving the can out at room temperature for an extended period, or storing it in a cabinet after opening, is not safe. Always return it to the refrigerator after each use.
FAQ: Does Cool Whip Need to Be Refrigerated After Opening?Yes. Once the tub is opened and thawed, it must stay refrigerated. It should not go back in the freezer per Kraft’s official guidance, though some sources note that a single refreeze after proper fridge-thawing causes minimal quality loss. Opened and thawed Cool Whip keeps in the refrigerator for 7 to 10 days. For how to tell if it has gone bad, see does whipped cream go bad.
FAQ: How Long Can Whipped Cream Sit Out on a Hot Day?When the ambient temperature is above 90 degrees Fahrenheit, the safe window for perishable foods at room temperature shrinks from 2 hours to 1 hour. This applies to all three types of whipped cream. At an outdoor summer gathering, whipped cream on a dessert should either be added at serving time or kept chilled over a bowl of ice until serving.
