Make a rich, tangy, no-bake key lime cheesecake with a simple graham cracker crust. This recipe is easy to prepare and perfect for summer desserts.

Ingredients

Scale
  • 1 1/2 cups graham cracker crumbs
  • 1/4 cup granulated sugar (for crust)
  • 6 tablespoons unsalted butter, melted
  • 2 (8 ounce) packages cream cheese, softened
  • 1 (14 ounce) can sweetened condensed milk
  • 1/2 cup fresh key lime juice (about 6-8 limes)
  • 1 teaspoon lime zest
  • 1 teaspoon vanilla extract
  • Optional: Whipped cream or lime slices for topping

Instructions

  1. Combine graham cracker crumbs and 1/4 cup sugar in a bowl. Pour in melted butter and mix until crumbs are evenly moistened.
  2. Press the crumb mixture firmly into the bottom of a 9-inch springform pan. Chill the crust in the refrigerator for 15 minutes.
  3. In a large bowl, beat the softened cream cheese with an electric mixer until smooth and creamy.
  4. Gradually beat in the sweetened condensed milk until fully combined.
  5. Stir in the key lime juice, lime zest, and vanilla extract until the mixture is uniform and slightly thickened.
  6. Pour the filling over the chilled crust. Spread the top evenly with a spatula.
  7. Cover the pan loosely with plastic wrap and refrigerate for at least 6 hours, or preferably overnight, until the cheesecake is firm.
  8. Before serving, carefully release the springform side. Top with whipped cream or lime slices if desired.

Notes

  • Use fresh key lime juice for the best tangy flavor; bottled juice changes the texture slightly.
  • If you cannot find key limes, use standard limes, but reduce the amount slightly as they are more acidic.
  • To make individual mini cheesecakes, use a muffin tin lined with paper liners and reduce the chilling time to about 4 hours.
