These Key Lime Pie Bars are bright, creamy, and perfectly tart with a crunchy graham cracker crust. They’re everything you love about Key lime pie in a fun, handheld version. Great for potlucks, parties, or an easy summer dessert!

Ingredients

Scale

For the Crust:

  • 1 ½ cups graham cracker crumbs

  • ¼ cup granulated sugar

  • 6 tablespoons unsalted butter, melted

  • Pinch of salt

For the Filling:

  • 3 large egg yolks

  • 1 (14 oz) can sweetened condensed milk

  • ½ cup fresh Key lime juice (or regular lime juice)

  • 1 tablespoon lime zest

  • Optional: powdered sugar for dusting or whipped cream for topping

Instructions

  1. Preheat oven to 350°F (175°C). Line an 8×8-inch or 9×9-inch baking pan with parchment paper, leaving an overhang on the sides.

  2. Make the crust:
    In a medium bowl, mix graham cracker crumbs, sugar, melted butter, and a pinch of salt until combined. Press firmly into the bottom of the pan.
    Bake for 8–10 minutes, then let cool slightly.

  3. Make the filling:
    In a large bowl, whisk together egg yolks and lime zest until slightly thickened, about 1 minute.
    Whisk in sweetened condensed milk until smooth. Add lime juice and mix until fully combined.

  4. Pour filling over the slightly cooled crust. Bake for 15–18 minutes, or until the center is just set (it will jiggle slightly).

  5. Let cool to room temperature, then refrigerate for at least 3 hours (or overnight) to firm up.

  6. Lift bars out of the pan using the parchment paper. Slice into squares and serve chilled. Top with whipped cream or dust with powdered sugar, if desired.

 


Notes

  • If you can’t find Key limes, regular limes work just as well!

  • Store in the fridge for up to 5 days or freeze for up to 2 months.

  • For extra lime flavor, add more zest or a splash of lime extract.
