Ingredients

2 cups heavy whipping cream
1/2 cup powdered sugar
1 teaspoon vanilla extract
8 oz cream cheese, softened

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

Directions

Prepare the graham cracker crust: In a medium bowl, combine the crushed graham crackers and melted butter. Stir until the crumbs are evenly coated with butter.
Press the mixture into the bottom of a 9×13-inch baking dish or a similar-sized dish to form a crust. Place the crust in the refrigerator while you prepare the filling.
Make the filling: In a large bowl, beat the heavy whipping cream, powdered sugar, and vanilla extract together until stiff peaks form.
In another bowl, beat the softened cream cheese until smooth. Add the sweetened condensed milk and key lime juice and mix until fully combined and smooth.
Gently fold the whipped cream into the cream cheese mixture until well incorporated. Be careful not to deflate the whipped cream too much.
Assemble the cake: Spread half of the key lime filling over the graham cracker crust in an even layer. Top with a layer of whole graham crackers, followed by the remaining filling.
Chill: Cover the cake and refrigerate for at least 4 hours, or overnight, to allow the layers to set and the flavors to meld together.
Before serving, garnish with lime zest, if desired.

Servings and Timing

This recipe makes about 12 servings. Preparation time is about 15 minutes, with a chilling time of at least 4 hours (or overnight) to allow the cake to set properly. The total time is around 4-6 hours, making it a great make-ahead dessert for busy days.

Variations

Different citrus: If you don’t have key limes, you can use regular limes or even lemons to make a citrus icebox cake with a similar tart flavor.
Add fruit: Top the cake with fresh fruit like raspberries, blueberries, or sliced strawberries for a colorful, fresh touch.
Chocolate graham crackers: Use chocolate graham crackers in place of regular ones to give the crust a rich, chocolatey flavor that pairs beautifully with the tangy key lime filling.
Coconut flavor: Add shredded coconut to the graham cracker crust or sprinkle on top for a tropical twist.
