Servings 12 bars



  • 9 whole graham crackers
  • 6 tablespoons butter, melted
  • 1/4 cup granulated white sugar


  • 4 ounces cream cheese, softened to room temperature
  • One 14-ounce can sweetened condensed milk
  • 4 large egg yolks
  • 1/2 cup key lime juice (look for Nellie & Joe's brand in the juice aisle)
  • pinch of salt


  • 1 cup heavy whipping cream
  • 1 tablespoon powdered sugar
  • 3 regular key limes, cut into thin slices and then cut in half


  • Preheat the oven to 350 degrees F. Spray an 8x8-inch pan with nonstick spray.


  • In a medium bowl, combine the graham cracker crumbs, butter and sugar. Stir until well combined. Press the crust mixture into the prepared pan. Bake for 8 minutes.


  • In a large bowl, use a mixer to combine the cream cheese, sweetened condensed milk, egg yolks, lime juice and salt; beat until well combined and smooth. Scrape the filling on top of the baked crust and smooth with a rubber spatula to make it even. Bake 15 to 20 minutes, or until the filling is set. Chill the cooked bars for at least 2 hours (or overnight).


  • In a medium bowl, use an electric mixer to whip the cream and sugar until the cream has thickened. Cut the bars into squares and move them to a serving platter. Spoon the whipped cream onto the bars and garnish with a piece of lime. Alternately, you can put the whipped cream into a piping bag and pipe it decoratively on top of each bar.
