Key Lime Pie

Quick Answer

To make Key Lime Pie, build a smooth filling around lime, condensed milk, and graham crackers, spread it into a crust, and chill it long enough to slice cleanly. It works because the filling is thick enough to feel rich without turning heavy.

Jump to Recipe

This key lime pie builds a smooth, tangy filling from lime juice, condensed milk, and a graham cracker crust, chilled until it slices clean. Simple ingredients, real key lime flavor.

It's a good summer dessert or a bright finish to a heavier meal. Chill it fully before slicing so the filling holds its shape.

  • 1 cup condensed milk
  • 1/2 cup graham crackers
  • 1/2 cup powdered sugar or condensed milk depending on the filling
  • 1 teaspoon vanilla or citrus zest

Instructions

  2. 2Whip or mix the filling built around lime, condensed milk, and graham crackers until smooth and thick enough to hold a clean slice.
  3. 3Spread into the crust evenly and chill until firm.
  4. 4Top just before serving if whipped cream or garnish belongs on the finish.

Pro Tips

  • A fully cooled crust matters for chilled pies.
  • Chill long enough for slices to set cleanly.
  • A little salt sharpens sweet pie fillings more than people expect.

Substitutions

A cookie crust can replace graham crackers easily.
Cream cheese gives structure if the filling feels too loose.
Fresh citrus zest wakes up peanut butter and chocolate as well as fruit pies.

Storage Instructions

Keep chilled and covered for up to 4 days.

Make Ahead

Pies are strong make-ahead desserts because the chill time helps.
