directions

Preheat your oven to 325°F (163°C) and prepare a springform pan by greasing it and lining the bottom with parchment paper.

In a bowl, combine graham cracker crumbs, melted butter, and a bit of sugar. Press the mixture firmly into the bottom of the pan to form the crust.

Bake the crust for 10 minutes, then set aside to cool.

In a large mixing bowl, beat the softened cream cheese until smooth and creamy.

Add sugar and beat until fully incorporated, then mix in sour cream, vanilla extract, key lime juice, and zest.

Add eggs one at a time, mixing on low speed and scraping down the sides as needed.

Pour the filling over the cooled crust and smooth the top.

Bake in a water bath for 55-65 minutes, or until the center is set but slightly jiggly.

Turn off the oven, crack the door open, and let the cheesecake cool inside for 1 hour.

Refrigerate the cheesecake for at least 4 hours, preferably overnight.

Before serving, top with whipped cream and additional lime zest if desired.

FAQs

What’s the difference between key lime and regular lime?

Key limes are smaller, more aromatic, and more tart than Persian (regular) limes, offering a unique flavor.

Why use a water bath?

A water bath helps prevent cracking by baking the cheesecake gently and evenly.

Can I make this cheesecake without a springform pan?

While a springform pan is ideal, you can use a deep pie dish or cake pan lined with parchment for easier removal.

Is this cheesecake very tart?

It has a noticeable tang from the lime juice, but it’s balanced by the creamy and sweet filling.

Can I use low-fat cream cheese?

Full-fat cream cheese is recommended for the best texture and flavor, but low-fat can be used if necessary.

Why does my cheesecake crack?

Cracks can result from overmixing or overbaking. Cooling it slowly and using a water bath helps minimize this.

Can I make this ahead of time?

What kind of sour cream should I use?

Use full-fat sour cream for the creamiest consistency.
