I’m such a fan of no bake cheesecakes (if you don’t believe me, just take a peek at my huge collection of no bake cheesecake recipes linked right here). They’re perfect for when you want something impressive but easy, and they feel a lot lighter than the classic baked versions—even though I absolutely love every kind of cheesecake out there.

Another one of my favorites is this bright Lemon Cheesecake, and if citrus isn’t what you’re after, my Easy Cheesecake Recipe is a fantastic go-to for any occasion.

I used to have a serious sweet tooth—still do, really—but as time goes on, I find that I can’t handle sugary desserts as intensely sweet as I once could.

Sometimes I’ll skip a rich chocolate cake in favor of something bright and fruity, or settle for a simple cookie instead of indulging in a big slice of frosted cake.

So, when it comes to tangy, citrusy desserts, that’s where I really shine.

Using a simple graham-cracker crust and pantry basics, you’ll get a dessert that looks like you worked all day but comes together in a flash.

What You’ll Need

• 2 1/2 cups graham crumbs, (350)
• 1/2 cup melted unsalted butter
• 3 packages full fat cream cheese, room temperature (24oz/750g)
• 1 1/2 cups powdered sugar, (200 grams)
• 1/4 cup key lime or lime juice, (2 limes)
• 1-2 tablespoon key lime or lime zest, (2 regular limes) Depending on your tastes
• 1 teaspoon vanilla
• 3/4 cup heavy whipping cream, cold, 30-35% fat ONLY
• sweetened whipped cream for garnish

Step-by-Step Preparation

1. Mix graham cracker crumbs with melted unsalted butter until combined.
2. Firmly press crumb mixture into the bottom and about 1″ up the sides of an 8″ or 9″ springform pan.
3. Beat room-temperature cream cheese in a large bowl with an electric mixer until completely smooth and creamy.
4. Add powdered sugar, lime juice, lime zest, and vanilla to the cream cheese and beat until silky and smooth.
5. In a separate chilled bowl, whip cold heavy whipping cream with an electric mixer to stiff peaks.

6. Gently fold whipped cream into the cream cheese mixture until combined, keeping it airy.

7. Taste the filling and adjust sweetness or lime to preference.
8. Spread the filling evenly over the prepared crust.
9. Cover and refrigerate the cheesecake for at least 5–6 hours or overnight until firm.

Pro Tips for Best Results

• Let your cream cheese sit out until it’s room temperature, then beat it alone first to avoid lumps and ensure a luscious filling.
• Keep the heavy cream cold and if you can, chill your mixing bowl ahead of time. Whip until stiff peaks form so it adds great structure to the filling.
• Fold the whipped cream in delicately to keep the cheesecake light and airy—overmixing will make it dense and heavy.
• Press that crust in firmly, and don’t forget to push it about an inch up the sides of your pan so it holds together beautifully when sliced.
• Refrigerate for at least 6 hours or overnight so the cheesecake sets just right. If you want firmer slices, give it extra fridge time.
• If freezing, thaw the cheesecake slowly on a cooling rack in your fridge to prevent the crust from getting soggy from excess moisture.
• If your powdered sugar feels clumpy, sift it first to get a perfectly smooth filling. Always taste before folding in whipped cream, and adjust the sugar or lime juice to fit your preference.

Flavor Swaps and Add-Ins

• Lemon lovers, swap the lime juice and zest for fresh lemon juice and zest for a classic lemon no bake cheesecake twist.
• Try adding ½ cup of toasted shredded coconut to the filling or sprinkle on top for a tropical coconut-lime flair.
• Switch up the crust by using crushed Oreos or buttery shortbread cookies instead of graham crackers for a richer foundation.
• For an extra pop of flavor and shine, spread a thin layer of store-bought or homemade lime curd on top before serving.
• Want smaller treats? Make mini cheesecakes in a muffin tin or little jars—they’re perfect for parties or portion control.
• For a lower-fat version, try lighter cream cheese or mix in some mascarpone for a silky texture (keep in mind the texture will be a bit different). If you’d prefer an even lighter, no-bake creamy dessert in jars, try our Raspberry Chia Pudding with Cottage Cheese.

Storing, Make-Ahead, and Freezing

Refrigerator

This no bake Key Lime Cheesecake is a perfect make-ahead dessert. You can prepare it 1–2 days in advance, just cover it tightly and keep it in the fridge. Just note that if you keep it longer, the crust might start to get a little soft.

Freezer

You can freeze this cheesecake too! However, I recommend eating it while it’s partially frozen, or thaw it slowly on a cooling rack in the fridge. That way, any moisture released as it thaws won’t ruin the crisp crust.

Following this thawing method will keep your cheesecake tasting just as fresh and creamy as the day you made it.

Common Questions Answered

• Can I use regular limes instead of key limes? Absolutely! Regular Persian limes work great here. Key limes tend to be a bit tarter and more fragrant, but either type will give you that wonderful lime flavor.
• How long should I chill the cheesecake? You’ll want to refrigerate it for at least 6 hours to let it fully set, though overnight chilling is best. You can make it 1 to 2 days ahead—just keep in mind the crust can soften after a couple of days.
• Can I freeze the cheesecake? Yes, you can freeze it fully or partially. Just make sure to thaw it on a cooling rack in the fridge so any extra moisture doesn’t soak the crust.
• Why is my filling lumpy? Lumps usually happen when the cream cheese is too cold. Let it come to room temperature and beat it well before adding anything else to get a smooth filling.
• Can I use whipped topping like Cool Whip instead of whipping cream? You can substitute it if needed, but keep in mind the texture and flavor won’t be quite the same. Real whipped cream gives you that light, creamy finish that makes this cheesecake special.
• How do I know when it’s set? The edges will feel firm and the center might still have a slight jiggle. After chilling overnight, it should be perfectly set and easy to slice.
• What pan should I use? An 8” or 9” springform pan works best for this no bake cheesecake. It makes lifting the slices out easy and keeps everything nice and neat.
