FAQs

Can I use regular lime juice instead of Key lime juice?

Yes. Key lime juice offers a more distinctive tart flavor, but regular fresh lime juice works well if that’s what you have.

Can I make this dessert ahead of time?

Absolutely. It’s even more flavorful after chilling for several hours or overnight.

Why use pineapple with its juice?

The pineapple juice helps dissolve and activate the instant pudding mix while adding sweetness and tropical flavor.

Can I use homemade whipped cream?

Yes. Stabilized homemade whipped cream is an excellent substitute for whipped topping.

Do I have to use graham cracker crumbs?

No, but they add the classic Key lime pie flavor and a pleasant crunchy texture.

Can I make this without marshmallows?

Yes. The marshmallows are optional and can be omitted if preferred.

Is this recipe gluten-free?

The fluff itself can be gluten-free if all packaged ingredients are certified gluten-free. Substitute gluten-free graham-style crumbs if needed.

Can I add cream cheese?

Yes. Softened cream cheese creates a richer, cheesecake-like version of this dessert.

How long will Vintage Key Lime Pie Fluff Salad stay fresh?

It will remain fresh in the refrigerator for up to 3 days when stored in an airtight container.
