We created this refreshing mini pie with a homemade crumb crust and a pudding-like lime filling. If you can’t find Key lime juice, regular lime juice works just fine. —Taste of Home Test Kitchen


  • 2/3 cup graham cracker crumbs
  • 2 tablespoons sugar
  • 3 tablespoons butter, melted
  • 1/2 cup sugar
  • 2 tablespoons all-purpose flour
  • 1 tablespoon plus 1-1/2 teaspoons cornstarch
  • 1/8 teaspoon salt
  • 1 cup water
  • 1 drop green food coloring, optional
  • 2 large egg yolks, room temperature, beaten
  • 2 tablespoons Key lime juice
  • 1 teaspoon butter
  • 1/2 teaspoon grated lime zest
  • Optional: Whipped cream, thinly sliced Key limes and additional grated lime zest


  1. In a small bowl, combine cracker crumbs and sugar; stir in butter. Press onto the bottom and up the sides of a 7-in. pie plate coated with cooking spray. Bake at 325° for 8-10 minutes or until lightly browned. Cool on a wire rack.
  2. In a small saucepan, combine the sugar, flour, cornstarch and salt; gradually stir in water and, if desired, food coloring. Cook and stir over medium heat until thickened. Remove from the heat. Stir a small amount of hot filling into egg yolks; return all to the pan, stirring constantly. Bring to a gentle boil; cook and stir 2 minutes longer. Remove from the heat. Gently stir in lime juice, butter and lime zest.
  3. Pour into crust. Cool for 15 minutes. Refrigerate for 1-2 hours. If desired, garnish with whipped cream, lime slices and zest. Refrigerate leftovers.
