Ingredients
  

  • Graham cracker crumbs: About 1 1/2 cups (from roughly 10–12 full sheets).
  • Granulated sugar: 3 tablespoons for the crust, plus 1/2 cup for the filling.
  • Unsalted butter: 6 tablespoons, melted.
  • Cream cheese: 16 ounces (two 8-ounce blocks), softened to room temperature.
  • Sweetened condensed milk: 1 can (14 ounces) for creamy sweetness and structure.
  • Fresh key lime juice: 1/2 cup. If you can’t find key limes, use regular Persian lime juice.
  • Lime zest: 1–2 teaspoons, finely grated (from key limes or regular limes).
  • Pure vanilla extract: 1 teaspoon.
  • Salt: A small pinch to balance sweetness.
  • Heavy cream: 3/4 cup, cold, for whipping.
  • Powdered sugar: 2 tablespoons, to stabilize the whipped cream.
  • Optional garnish: Extra lime zest, thin lime slices, or whipped cream swirls.

Method
 

  1. Prep the pan: Lightly grease a 9-inch springform pan. Line the bottom with parchment for easy removal. If you don’t have a springform, use a deep 9-inch pie dish.
  2. Make the crust: In a bowl, combine graham cracker crumbs, 3 tablespoons sugar, and melted butter. Stir until evenly moistened and the mixture looks like wet sand.
  3. Press and chill: Press the crumb mixture firmly into the bottom and 1–1.5 inches up the sides of the pan. Use the bottom of a measuring cup to compact it. Chill for at least 20 minutes while you make the filling.
  4. Whip the cream: In a cold bowl, beat heavy cream with powdered sugar to medium-stiff peaks. Set aside. This will lighten the filling and help it set.
  5. Beat the cream cheese: In a separate large bowl, beat softened cream cheese until completely smooth and fluffy, about 2 minutes. Scrape the bowl well so there are no lumps.
  6. Add the sweeteners and flavor: Mix in the granulated sugar, sweetened condensed milk, vanilla, and a pinch of salt. Beat until silky and fully combined.
  7. Add lime: Stir in the lime zest and lime juice. The mixture will thicken slightly as the citrus interacts with the dairy.
  8. Fold in whipped cream: Gently fold the whipped cream into the lime filling in two additions. Keep it airy to maintain a light texture.
  9. Fill the crust: Pour the filling into the chilled crust. Smooth the top with an offset spatula. Tap the pan gently to release any air bubbles.
  10. Chill to set: Cover and refrigerate for at least 6 hours, preferably overnight. The longer chill ensures clean slices and the best texture.
  11. Garnish and serve: Run a knife around the edge before releasing the springform. Top with lime zest, thin lime slices, or dollops of whipped cream. Slice with a warm, dry knife for neat pieces.
