4.9 from 51 reviews

These Key Lime Pie Bars offer a delightful twist on the classic Key Lime Pie, featuring a buttery graham cracker crust topped with a tangy, creamy key lime filling. Perfectly baked until set and chilled to perfection, these bars are finished with a dollop of whipped cream and fresh lime zest for an irresistible citrusy treat.

Ingredients

Scale

Crust

  • 2.5 cups graham cracker crumbs
  • 0.75 cup granulated sugar
  • 0.5 cup unsalted butter, melted

Filling

  • 14 ounce sweetened condensed milk
  • 0.5 cup key lime juice (freshly squeezed)
  • 0.5 cup sour cream
  • 4 large egg yolks

Topping

  • 1 cup whipped cream
  • 0.5 cup lime zest

Instructions

  1. Preheat and prepare pan: Preheat your oven to 350°F (175°C) and line a 9×13 inch baking pan with parchment paper, leaving an overhang on the sides to help lift out the bars later.
  2. Make the crust: In a medium bowl, combine the graham cracker crumbs and granulated sugar. Pour in the melted butter and stir until the mixture is well combined. Press the crust mixture evenly into the bottom of the prepared pan.
  3. Bake the crust: Bake the crust for 8-10 minutes until it turns lightly golden. Remove it from the oven and let it cool slightly.
  4. Prepare the filling: In a large bowl, whisk together the sweetened condensed milk, freshly squeezed key lime juice, sour cream, and egg yolks until smooth and fully combined.
  5. Assemble and bake: Pour the lime filling over the cooled crust and smooth the top evenly with a spatula. Bake for 15-20 minutes, or until the filling is set but still has a slight wobble in the center to ensure it doesn’t overbake.
  6. Cool and chill: Remove from the oven and let the bars cool completely in the pan on a wire rack. Once cooled, refrigerate for at least 2-3 hours or until firm.
  7. Serve: Use the parchment paper overhang to lift the bars out of the pan and cut them into squares. Top each bar with whipped cream and lime zest before serving for extra flavor and presentation.

Notes

  • For best flavor, use fresh key lime juice rather than bottled.
  • Ensure not to overbake the filling to maintain a creamy texture with a slight wobble.
  • Chilling is essential for the bars to set properly; do not skip refrigeration.
  • The parchment paper overhang makes it easy to remove the bars without damage.
  • These bars can be stored in an airtight container in the refrigerator for up to 3 days.
