Description

These Key Lime Bars are sweet, tangy, and perfectly creamy, with a buttery graham cracker crust and a zesty key lime filling. They’re easy to make and perfect for summer, holidays, or anytime you crave a refreshing citrus dessert!


Ingredients

Scale

For the Crust:

  • 1 1/2 cups graham cracker crumbs (about 12 crackers, finely crushed)
  • 1/4 cup granulated sugar
  • 6 tbsp unsalted butter (melted)

For the Key Lime Filling:

  • 4 large egg yolks
  • 1 can (14 oz) sweetened condensed milk
  • 1/2 cup key lime juice (freshly squeezed preferred, or bottled key lime juice)
  • 1 tbsp lime zest (adds extra citrus flavor!)

For Garnish (Optional):

  • Powdered sugar (for dusting)
  • Whipped cream
  • Extra lime zest or lime slices

Instructions

Step 1: Prepare the Crust

  1. Preheat oven to 350°F (175°C).
  2. Line a 9×9-inch baking pan with parchment paper, leaving some overhang for easy removal.
  3. In a bowl, mix graham cracker crumbs, sugar, and melted butter until combined.
  4. Press the mixture firmly into the bottom of the pan.
  5. Bake for 8-10 minutes, until lightly golden. Let cool slightly.

Step 2: Make the Key Lime Filling

  1. In a medium bowl, whisk together egg yolks, sweetened condensed milk, key lime juice, and lime zest until smooth.
  2. Pour the mixture over the slightly cooled crust and spread evenly.

Step 3: Bake & Chill

  1. Bake for 15-18 minutes, until the edges are set but the center is slightly jiggly.
  2. Let cool at room temperature for 30 minutes, then refrigerate for at least 2 hours (or overnight) for best results.

Step 4: Slice & Serve

  1. Lift the bars out using the parchment paper overhang.
  2. Slice into 16 squares.
  3. Dust with powdered sugar, top with whipped cream, and garnish with lime zest or slices.

Notes

  • No Key Limes? Use regular lime juice or a mix of lemon & lime juice for a similar taste.
  • Make Ahead: These bars store well in the fridge for up to 5 days.
  • Gluten-Free Option: Use gluten-free graham crackers for the crust.
  • Extra Tart? Add 1 more tbsp of lime juice for an extra zing!
