Kitchen Tools You’ll Need

Mixing bowls
Electric mixer
Measuring cups and spoons
9-inch springform pan
Rubber spatula
Whisk

Ingredients

1 cup finely ground graham crackers (from 9 crackers, for structure and crunch)
3 tablespoons sugar (adds sweetness)
½ teaspoon kosher salt (enhances flavor)
5 tablespoons unsalted butter, melted and cooled (binds the crust together)
2 packages (8 ounces each) cream cheese, room temperature (provides creaminess)
1 can (14 ounces) sweetened condensed milk (adds sweetness and creaminess)
⅓ cup fresh Key lime juice (gives the cheesecake its signature tart flavor)
2 teaspoons grated lime zest (enhances lime flavor)
Thinly sliced lime rounds for serving (for garnish)
½ teaspoon pure vanilla extract (rounds out the flavor)
½ cup cold heavy cream (whipped to create a light texture)

How to Make No-Bake Key Lime Cheesecake

Step 1. Begin by preparing the crust. In a mixing bowl, combine the finely ground graham crackers, sugar, and kosher salt. Pour in the melted unsalted butter and stir until the mixture resembles wet sand. This will create a crumbly, cohesive texture that will hold your crust together.

Step 2. Press the graham cracker mixture firmly into the bottom of a 9-inch springform pan. Use your fingers or the bottom of a flat measuring cup to evenly distribute the crumbs, creating a solid base. Make sure the crust is compact to support the filling once it sets.

Step 3. In another bowl, add the cream cheese. Using an electric mixer, beat the cream cheese until it’s smooth and creamy, which typically takes a few minutes. This step is crucial for ensuring that your cheesecake has a velvety texture without lumps.

Step 4. Slowly pour in the sweetened condensed milk while continuing to mix on low speed. This will add creaminess and sweetness to the filling without making it too dense. Mix until fully combined and smooth.

Step 5. Add the fresh Key lime juice, grated lime zest, and pure vanilla extract to the cream cheese mixture. Beat until everything is well incorporated, and the filling is light and airy. The vibrant lime juice gives the cheesecake its distinctive flavor, while the zest enhances that citrus note.

Serving Suggestions

This cheesecake is versatile enough to serve at various occasions. It works wonderfully as a light breakfast on special mornings when you want something sweet yet refreshing. It makes for a perfect snack on a warm afternoon or serves beautifully at family meals and gatherings. Any leftovers can be enjoyed as dessert the following day, making it an excellent make-ahead option for hosting or casual evenings.

Pro Tips for Best Results

Allow the cream cheese to reach room temperature before mixing. This ensures a smooth filling without lumps.
When folding in the whipped cream, do it gently to maintain the airy texture.
For a firmer cheesecake, increase the chilling time to a full overnight if possible.
To slice more easily, dip your knife in warm water and wipe it clean between cuts.
Use fresh Key limes for the best flavor, but bottled key lime juice can be a convenient alternative.
Pay attention to the consistency of the crust; it should hold together when pressed, but not be overly wet.

Common Mistakes to Avoid

Using Cold Cream Cheese: Starting with cold cream cheese can result in a lumpy filling. Let it soften to room temperature for easy mixing and smooth consistency.
Not Whipping the Cream Enough: If the heavy cream isn’t whipped to stiff peaks, the filling may end up flat and dense. Whip until the peaks hold their shape to create a light texture.
Skipping the Chilling Process: Not allowing the cheesecake to set properly can cause it to be too soft when you slice it. Patience is key for a neat finish.
Overmixing the Filling: Mixing the filling too vigorously can deflate the whipped cream, resulting in a denser cheesecake. Use gentle folding motions to combine while retaining airiness.
Uneven Crust: If the crust isn’t pressed firmly and evenly, it might crumble when serving. Make sure to pack it tightly into the pan.
Not Grating the Lime Zest: Omitting lime zest can result in a less vibrant flavor. The zest adds an aromatic lift, enhancing the overall taste of the cheesecake.

Variations & Substitutions

For a twist, you can add crushed fruit like berries or mangoes blended into the filling for a different flavor profile. You might also consider using a flavored extract, such as coconut, to create a unique layering of flavors. Additionally, consider different types of cookies for the crust base—gingersnaps or vanilla wafers can introduce new flavors to the dish.

Storage & Reheating

Store your no-bake cheesecake covered in the refrigerator, where it will stay fresh for about one week. If you want to keep it longer, you can freeze it for up to three months. For freezing, be sure to wrap it tightly to prevent freezer burn. When reheating, there is no need, as it is best enjoyed chilled straight from the fridge.
