Instructions

To make the graham cracker crust

  • Preheat the oven to 350°F, and grease a 9x13-inch pan or line with parchment paper.
  • In a medium bowl, stir together the graham cracker crumbs, and sugar. Add the melted butter and mix until evenly coated and the texture resembles wet sand.

  • Press the crust mixture firmly and evenly into the bottom of the prepared pan. Use the bottom of a measuring cup to pack it down tightly.
  • Bake for 10 minutes, until lightly golden brown and set. Remove from the oven and let cool slightly while you prepare the filling.

To make the filling

  • In a large bowl, beat the softened cream cheese until completely smooth and free of lumps.

  • Add the egg yolks and mix until fully incorporated. Pour in the sweetened condensed milk and beat until smooth.

  • Add the key lime juice and lime zest. Mix until fully combined. The mixture will thicken slightly. Pour the filling over the warm crust and spread evenly.
    1 cup key lime juice, 1 heaping tablespoon lime zest
  • Bake for 20–25 minutes, just until the center is set with a slight jiggle in the middle. Do not allow the top to brown.
  • Cool at room temperature for 30–45 minutes, then refrigerate for at least 4 hours or until fully chilled and firm.

To make the topping

  • In a large bowl, beat the heavy whipping cream and powdered sugar until stiff peaks form.
    2 cups heavy whipping cream, ¼ cup powdered sugar
  • Spread the whipped cream evenly over the chilled bars, and add more lime zest if desired.
  • Slice into squares with a sharp knife, wiping the blade clean between cuts for neat slices.
