What Makes This Recipe So Good
- No baking required: Keep the kitchen cool and still enjoy a decadent dessert.
- Fast and simple: Easy ingredients and quick assembly mean dessert is ready in under 30 minutes, plus chill time.
- Bright, balanced flavor: The zesty key lime cuts through the rich cheesecake for a refreshing bite.
- Perfect for portion control: Cups make serving neat, cute, and customizable.
- Great make-ahead option: They set beautifully in the fridge and taste even better the next day.
What You’ll Need
- Cream cheese: Use full-fat, softened to room temperature for a smooth, rich filling.
- Sweetened condensed milk: Adds sweetness and that classic no-bake cheesecake texture.
- Heavy whipping cream: Whipped to stiff peaks for lightness and body.
- Key lime juice: Fresh is best; bottled works in a pinch. Regular lime juice is fine if key limes aren’t available.
- Lime zest: Adds fragrant citrus oils and extra zing.
- Graham crackers: Crushed for the crumb base. Shortbread or vanilla wafers also work.
- Butter: Melted, to bind the crumbs.
- Granulated sugar: A little for the crust to sweeten and crisp it.
- Vanilla extract: Rounds out the flavor of the filling.
- Salt: Just a pinch to balance the sweetness.
- Optional toppings: Whipped cream, extra lime zest, thin lime slices, or toasted coconut.
Step-by-Step Instructions
- Prep the cups: Set out 8 to 10 small dessert cups, jars, or ramekins.
Clear glasses look especially nice for layering.
- Make the crumb base: In a bowl, mix 1 1/2 cups crushed graham crackers, 2 tablespoons granulated sugar, and 6 tablespoons melted butter. Stir until the crumbs look like damp sand and clump slightly when pressed.
- Press the crust: Spoon 2 to 3 tablespoons of crumbs into each cup. Press down gently with the back of a spoon.
Pop the cups in the fridge while you make the filling.
- Whip the cream: In a cold bowl, whip 3/4 cup heavy cream to stiff peaks. Set aside. This keeps the filling light and mousse-like.
- Beat the cream cheese: In a separate bowl, beat 16 ounces softened cream cheese until very smooth and fluffy, about 1 to 2 minutes.
Scrape the bowl so there are no lumps.
- Add the sweetener and flavor: Beat in 3/4 cup sweetened condensed milk, 1 teaspoon vanilla extract, a pinch of salt, 1/2 cup key lime juice, and 1 to 2 teaspoons lime zest. Mix until fully combined and silky. Taste and adjust lime to your preference.
- Fold in the whipped cream: Gently fold the whipped cream into the lime-cream cheese mixture with a spatula.
Keep it airy—don’t overmix.
- Fill the cups: Spoon or pipe the cheesecake filling over the chilled crusts, leaving a little space at the top for garnish.
- Chill to set: Cover and refrigerate for at least 2 hours, ideally 4. Overnight is great for the best texture and flavor.
- Garnish and serve: Top with a dollop of whipped cream, a sprinkle of zest, or a thin lime slice. Serve cold.
How to Store
- Refrigerate: Cover cups tightly and chill for up to 4 days.
The crust will soften slightly over time but still tastes great.
- Avoid freezing fully assembled: Freezing can change the texture of the filling. If you must freeze, do so before adding toppings and thaw gently in the fridge.
- Transport tips: Keep cups cold in an insulated bag with ice packs. Add whipped cream at the destination to keep it neat.
Benefits of This Recipe
- Time-saving: Minimal prep and zero oven time means dessert without the wait.
- Beginner-friendly: Simple steps and forgiving measurements make it hard to mess up.
- Customizable portions: Make mini cups for a crowd or larger jars for a more indulgent serving.
- Fresh and light flavor: The citrus balances the creaminess, so it never tastes heavy.
- Ideal for gatherings: Easy to scale and assemble ahead, so you’re not scrambling at the last minute.
What Not to Do
- Don’t use cold cream cheese: Cold blocks won’t whip smooth and can leave lumps.
Let them soften to room temp first.
- Don’t skip the chill time: The filling needs time to firm up. Rushing will give you runny cups.
- Don’t overmix after adding whipped cream: Vigorous stirring deflates the mixture and makes it dense.
- Don’t add too much lime juice without adjusting: Too much liquid can loosen the filling. Balance with more cream cheese if you increase the juice.
- Don’t pack the crust too hard: Overly firm crusts are tough to scoop.
Press gently for a tender bite.
Variations You Can Try
- Coconut-lime cups: Stir 1/4 cup shredded toasted coconut into the crust and garnish with more on top.
- Berry swirl: Spoon a little raspberry or strawberry sauce between layers for a sweet-tart contrast.
- Gingersnap crust: Swap grahams for crushed gingersnaps to add warm spice against the lime.
- Mini pies: Use store-bought mini graham crusts if you prefer a classic pie look.
- Greek yogurt lightened: Replace 4 ounces of cream cheese with 1/2 cup thick Greek yogurt for a tangier, slightly lighter filling.
- Dairy-free option: Use dairy-free cream cheese, coconut cream (whipped), and vegan condensed coconut milk. Taste and adjust lime and sweetness.
- Chocolate crunch: Add a thin layer of melted white chocolate over the crust before filling for a sweet snap.

FAQ
Can I use regular limes instead of key limes?
Yes. Regular Persian limes work well and are easier to find.
Key limes are a bit more floral and tart, but the difference is subtle in this recipe.
Why is my filling runny?
It may not have chilled long enough, or your cream cheese wasn’t fully softened and blended smoothly. Too much lime juice can also thin the mixture. Make sure to whip the cream to stiff peaks and fold it in gently.
Can I make these a day ahead?
Absolutely.
They set beautifully overnight and the flavors meld. Add whipped cream and garnishes right before serving for the neatest look.
What size cups should I use?
Four to eight-ounce cups work best. Smaller cups are great for parties, while 8-ounce jars feel like a full dessert.
Adjust crumb and filling amounts to suit your container size.
How do I crush graham crackers without a food processor?
Place the crackers in a zip-top bag and roll them with a rolling pin until fine. A few small bits add nice texture.
Is sweetened condensed milk the same as evaporated milk?
No. Sweetened condensed milk is thicker and sweetened, which gives body and sweetness to the cheesecake.
Evaporated milk is unsweetened and too thin for this recipe.
Can I make this less sweet?
Yes. Reduce the sweetened condensed milk slightly and add an extra tablespoon of lime juice. Taste as you go so the balance stays bright, not sour.
How long can they sit out?
Keep them chilled as much as possible.
For serving, 1 to 2 hours at cool room temperature is fine, but return leftovers to the fridge promptly.
In Conclusion
No-bake key lime cheesecake cups are the kind of dessert that checks all the boxes: quick, refreshing, and downright pretty. The creamy filling and zesty lime feel luxurious without any baking drama. Keep a batch in the fridge for summer nights, bring them to a potluck, or dress them up for a dinner party.
