Print Recipe Pin Recipe

Ingredients
  

For the Crust:

  • 1 11-ounce box vanilla wafers
  • 2 tbsp. granulated sugar
  • 8 tbsp. unsalted butter, melted

For the Filling:

  • 1 ¾ cup condensed milk
  • 5 large egg yolks
  • ¾ cup key lime or conventional lime juice
  • 1 tsp. lime zest

For the Topping:

  • 1 cup cold heavy cream
  • 1 tbsp. confectioners’ sugar

Instructions
 

To prepare the crust:

  • Pre-heat oven to 350°F.
  • Line a 9-inch square pan with parchment paper, leaving a 2-inch overhang on two sides.
  • In a food processor, combine vanilla wafers and sugar, and pulse until you have fine crumbs.
  • Add butter and process until evenly moistened.
  • Transfer mixture to prepared pan and press down into an even layer.
  • Bake until fragrant and a shade darker, 15 to 17 minutes.

To prepare the filling:

  • Meanwhile, in a medium bowl, whisk together condensed milk, egg yolks, lime juice and lime zest.

To prepare the key lime bars:

  • Remove bars from oven, after baking is complete, and pour filling over crust; it’s ok if the crust is still warm.
  • Bake until the filling is set, about 15 minutes.
  • Remove from oven and transfer to a rack to cool completely; then cover and refrigerate for at least 4 hours.
  • Use a sharp knife to release edges.
  • Using the parchment overhang, carefully lift and transfer the bar to a cutting board.
  • Just before serving, whip heavy cream and confectioners’ sugar until soft peaks form.
  • Top bars with whipped cream and cut into ~16 squares.
