Can I use regular limes instead of key limes?

Yes, you can substitute regular Persian limes if key limes aren't available. The flavor will be slightly different—less intensely aromatic and a bit less tart—but still delicious. You might want to add a bit of lime zest to amp up the flavor when using regular limes.

Why did my cheesecakes crack on top?

Cracking usually happens from either overmixing the batter (incorporating too much air), overbaking, or cooling too quickly. Next time, mix just until ingredients are combined, watch your baking time carefully, and allow the cheesecakes to cool gradually at room temperature before refrigerating.

Can I make these without a stand mixer?

Absolutely! While a stand mixer makes the process easier, you can achieve great results with a hand mixer or even mixing vigorously by hand with a spatula or wooden spoon. The key is ensuring your cream cheese is very soft so you can work out all the lumps.

How do I know when the cheesecakes are done baking?

Perfect mini cheesecakes should be mostly set around the edges but still have a slight jiggle in the center—about the size of a quarter. They'll continue to firm up as they cool. If they're completely firm throughout when you remove them from the oven, they're likely overbaked.

Ingredients You’ll Need

Graham Cracker Crumbs: These form the foundation of our classic crust, providing that distinctive honey-sweet flavor and perfect crumbly texture that complements the creamy filling.
Butter: Melted butter binds the graham cracker crumbs together, creating a firm yet tender crust that holds its shape when sliced.
Granulated Sugar: Added to both the crust and filling, it provides sweetness that balances the tanginess of the key lime and cream cheese.
Cream Cheese: The star of any cheesecake, cream cheese creates that luxuriously smooth texture we all crave. Make sure it’s fully softened for a lump-free batter.
Sour Cream: This secret ingredient adds extra creaminess and a subtle tang that enhances the key lime flavor.
Eggs: They provide structure and richness to the filling, helping it set properly during baking.
Key Lime Juice: The essential flavoring that gives these cheesecakes their refreshing, tropical taste. Fresh is best, but bottled works in a pinch.
Vanilla Extract: A warming background note that rounds out the citrus flavor and adds depth.
Whipped Cream: A billowy topping that adds a light, airy contrast to the dense cheesecake beneath.
Key Limes: Optional garnish that adds a beautiful finishing touch and signals the flavor within.

Variations

Flavor Twists

Chocolate Key Lime: Use chocolate graham crackers for the crust to create an interesting flavor contrast.

Dietary Adaptations

Lighter Version: Substitute Neufchâtel cheese (1/3 less fat cream cheese) and light sour cream to reduce calories without sacrificing too much flavor.
Gluten-Free Option: Use gluten-free graham crackers or cookies for the crust component.

How to Make Key Lime Mini Cheesecakes

Step 1: Prepare the Crust

Preheat your oven to 325°F and line a 12-cup muffin tin with paper liners. In a medium bowl, combine graham cracker crumbs, melted butter, and sugar until the mixture resembles wet sand. Divide the mixture among the liners (about 2 tablespoons per cup) and press firmly to create an even base. Bake for 5 minutes until slightly set, then remove and cool completely.

Step 2: Make the Cheesecake Filling

Once the crusts have cooled, prepare your filling. In a stand mixer fitted with the paddle attachment, beat the cream cheese until completely smooth. This step is crucial – no one wants lumpy cheesecake! Add sour cream, sugar, eggs, key lime juice, and vanilla extract. Mix on low speed until the ingredients are fully incorporated and the batter is silky smooth, stopping to scrape down the sides of the bowl as needed.

Step 3: Fill and Bake

Divide the cheesecake batter evenly among the prepared crusts, filling each liner almost to the top. Tap the pan gently on the counter to release any air bubbles. Bake for 20 minutes, until the edges are set but the centers maintain a slight jiggle. The cheesecakes will continue firming up as they cool.

Step 4: Cool and Chill

Allow the cheesecakes to cool at room temperature for 30 minutes. This gradual cooling helps prevent the tops from cracking. Then transfer to the refrigerator for at least 30 minutes (though longer is better) to fully set.

Step 5: Garnish and Serve

Just before serving, top each mini cheesecake with a swirl of whipped cream and a small slice of key lime for an elegant presentation that hints at the flavor inside.

Pro Tips for Making the Recipe

Room Temperature Ingredients: Ensure your cream cheese, sour cream, and eggs are at room temperature before mixing. Cold ingredients don’t blend as smoothly and can lead to a lumpy batter.
Don’t Overmix: Once you add the eggs, mix just until combined. Overmixing incorporates too much air, which can cause the cheesecakes to rise too quickly in the oven and then crack as they cool.
The Jiggle Test: The centers should still have a slight wobble when you remove them from the oven – they’ll continue to cook from residual heat and then set fully when chilled.
Cooling Gradually: Allow the cheesecakes to cool at room temperature before refrigerating. Sudden temperature changes can cause the tops to crack.
Make the Most of Your Limes: Before juicing your key limes, roll them firmly under your palm on the counter to help release more juice. And don’t forget to zest them first if you want an extra punch of lime flavor!

How to Serve

These versatile mini cheesecakes can be presented in various ways depending on the occasion:

Casual Serving

For family desserts or casual gatherings, serve them right in their liners topped with a dollop of whipped cream and perhaps a sprinkle of graham cracker crumbs.

Elegant Presentation

For dinner parties or special occasions, carefully remove the paper liners and place each cheesecake on a small dessert plate. Add a perfectly piped swirl of whipped cream, a thin slice of key lime, and perhaps a mint leaf for color contrast.

Perfect Pairings

Serve alongside fresh berries for a bright, complementary flavor
Pair with coffee or espresso – the bitterness contrasts beautifully with the sweet-tart cheesecakes
For an adult dessert, serve with a small glass of limoncello or a dessert wine

Make Ahead and Storage

Make Ahead

These mini cheesecakes actually benefit from being made a day ahead. The flavors have time to meld and develop, and the texture becomes even more luscious after a full night in the refrigerator.

Storing Leftovers

Keep any uneaten cheesecakes in an airtight container in the refrigerator for up to 4 days. I recommend adding the whipped cream topping just before serving rather than storing the cheesecakes with it.

Freezing

These mini cheesecakes freeze beautifully! Place them in a single layer in an airtight container and freeze for up to 2 months. For extra protection against freezer burn, wrap each individual cheesecake in plastic wrap before placing in the container.

Reheating (or Rather, Thawing)

To enjoy frozen cheesecakes, thaw them overnight in the refrigerator or at room temperature for about 2 hours. Add fresh whipped cream and garnishes after thawing.
