Key Lime Pie Bars

Key Lime Pie Bars

There are few desserts that make me think of carefree vacation days filled with sunshine and warm ocean breezes more than key lime pie. It has a smooth, light texture and is packed with a lime punch. The flavor of citrus – be it lemon, lime, orange, etc. – always makes me think of sunny days; it has such a bright flavor. Last year, I made my first key lime pie and was pleasantly surprised at how easy it was to assemble and bake. I’m a big fan of portable desserts and with summer picnics in full force right now, I thought that a key lime bar was long overdue.

Key Lime Pie Bars

Just as with the pie, these bars came together in no time at all. You’d think that a creamy pie filling such as this would require a tedious curd, but instead you simply whisk together a tiny bit of cream cheese, lime zest, sweetened condensed milk, an egg yolk and lime juice… pour into the crust and bam! Done!

While key limes can sometimes be hard to come by unless you live in a major citrus-growing area, you can also substitute regular limes for both the zest and the juice. The crust is made with animal crackers (my inner kid loved munching on the leftovers!), but if you can’t find them, you could easily use graham crackers or your favorite basic cookie for the crumb crust.

A crunchy crumb crust combined with a cool, creamy filling and zesty lime flavor is the perfect recipe for a hot summer day.

A recipe for Key Lime Pie Bars - all the wonderful flavors of the pie, but in easy bar form!


For the Crust:

  • 5
    animal crackers
  • 3
    light brown sugar
  • Pinch
    of salt
  • 4
    unsalted butter
    (melted and cooled slightly)

For the Filling:

  • 2
    cream cheese
    (at room temperature)
  • 1
    grated lime zest
  • Pinch
    of salt
  • 14
    canned sweetened condensed milk
  • 1
    egg yolk
  • ½
    Key lime juice

For the Garnish:

  • ¾
    shredded coconut
    (sweetened or unsweetened, toasted)


  1. Preheat oven to 325 degrees F. Line an 8-inch square baking pan with foil, allowing the extra foil to hang over the edges of the pan. Lightly coat with non-stick cooking spray; set aside.
  2. Make the Crust: Process the animal crackers in a food processor until finely ground, about 10 seconds. Add the brown sugar and salt and pulse a few times to combine. Drizzle the melted butter over the crumbs and pulse until the crumbs are evenly moistened, about 10 pulses. Press the crumbs evenly into the bottom of the pan. Bake until golden brown, 18 to 20 minutes. Place the pan on a wire rack while you prepare the filling.
  3. Make the Filling: Stir together the cream cheese, lime zest and salt in a medium bowl. Add the sweetened condensed milk and whisk until completely incorporated and no lumps remain. Whisk in the egg yolk, then add the lime juice and whisk gently until incorporated.
  4. Pour the filling into the crust and smooth into an even layer. Bake until the filling set and the edges are beginning to pull away slightly from the sides of the pan, 15 to 20 minutes. Place the pan on a wire rack and cool to room temperature, 1 to 2 hours. Cover with foil and refrigerate until thoroughly chilled, at least 2 hours or overnight.
  5. When ready to serve, run a paring knife around the edges of the pan and lift the bars from the pan using the foil overhangs. Cut into 16 squares and sprinkle with toasted coconut, if desired. Leftovers can be refrigerated in an airtight container for up to 2 days.
