Meringue

  • 2 egg whites

Instructions 

  • Preheat oven to 350 degrees F. Line a 12-cup muffin pan with liners and set aside.

Crust

  • To make the crust, process the graham crackers in a food processor until fine crumbs. Add melted butter and mix until combined.

Filling

  • Whisk together the sweetened condensed milk, lime juice, zest, vanilla, egg, and egg yolks. Pour into the baked crusts (about 45 g of filling per pie). Bake for 15-18 minutes, or until the filling is set. Remove from oven and allow to cool completely. Chill the pies for at least 2 hours or overnight.
    1 can sweetened condensed milk, ⅓ cup lime juice, 1 tbsp lime zest, 1 tsp vanilla extract, 1 egg, 2 egg yolks

Meringue

  • Whisk egg whites and sugar in a heat-resistant bowl over a double boiler. Whisk until the egg whites reach 150°F. Remove from the heat and beat with a hand mixer or in a stand mixer fitted with the whisk attachment until the meringue has cooled completely and stiff peaks are formed.
    2 egg whites, ½ cup sugar

Assembly

  • Transfer the meringue to a piping bag fitted with a piping tip. Pipe the meringue on the chilled pies and then use a kitchen torch to gently toast the tops. Top with lime zest and a lime wedge. Serve.

Notes

  • Storage: Store leftover pies covered in the refrigerator (covered) for up to 1 week. 
  • Make ahead: You can prepare the pies up to 1 day in advance and store in the refrigerator until ready to serve.
  • Topping: If you are not a fan of meringue, you can top the pies with whipped cream.
  • Full size key lime pie: You can bake this recipe in an 8-inch tart pan. The ingredient measurements and baking times remain the same.
  • Can I use regular limes in place of Key limes? Yes, if you cannot find Key limes, you can use regular limes.
  • Can I use bottled lime juice for Key Lime Pie? You can use bottled lime juice, but I recommend using fresh squeezed juice for the best taste.
