FAQs

Can I use regular limes instead of key limes?

Yes, regular limes work just fine. You can also use a mix of lemon and lime juice to mimic the unique flavor of key limes.

Can I freeze this cheesecake?

Yes, this cheesecake freezes well. Wrap it tightly and freeze for up to a month. Thaw in the fridge before slicing.

Why isn't my filling thickening?

Make sure your heavy cream is very cold and that you beat it to stiff peaks. Warm cream or under-whipping can result in a loose texture.

Can I make this ahead of time?

Absolutely. This is a perfect make-ahead dessert. Prepare it a day in advance and refrigerate until ready to serve.

What’s the best way to slice the cheesecake cleanly?

Use a sharp knife dipped in hot water and wiped dry between slices for clean, smooth cuts.

Is this cheesecake gluten-free?

The filling is gluten-free, but you’ll need to use gluten-free graham crackers for the crust.

Can I use a store-bought crust?

Yes, a store-bought graham cracker crust can save time, though it may not hold as much filling.

What can I use instead of cream cheese?

Mascarpone is a good substitute, but the flavor and texture will be slightly different.

Can I use bottled key lime juice?

Yes, bottled key lime juice is a great substitute when fresh key limes aren’t available.

Do I need gelatin to set this cheesecake?

No gelatin is required. The whipped cream combined with the cream cheese creates a firm yet creamy texture once chilled.
