These Key Lime Bars are bright, creamy, and irresistibly tangy with a buttery graham cracker crust and a smooth citrus filling. Topped with whipped cream and fresh lime slices, they’re the perfect make-ahead dessert for summer parties, potlucks, or anytime you need a refreshing treat.

Ingredients

  • For the Crust:
  • Cooking spray
  • 9 graham crackers, crushed
  • 6 tbsp butter, melted
  • ¼ cup granulated sugar
  • For the Filling & Assembly:
  • 4 oz cream cheese, room temperature
  • 4 large egg yolks
  • 1 (14 oz) can sweetened condensed milk
  • ½ cup fresh lime juice
  • Pinch of kosher salt
  • 1 cup Cool Whip
  • Zest of 1 lime
  • 3 Key limes or 2 regular limes, sliced for garnish

Instructions

  1. Preheat oven to 350°F. Grease an 8″ x 8″ baking pan with cooking spray.
  2. Mix crushed graham crackers, melted butter, and sugar in a medium bowl. Press into the prepared pan.
  3. Bake crust for 10 minutes, until slightly darkened and fragrant.
  4. In a large bowl, beat cream cheese until smooth.
  5. Add egg yolks, sweetened condensed milk, lime juice, and salt. Beat until fully combined.
  6. Pour filling over baked crust. Bake for 15–20 minutes, until the center is set.
  7. Let bars cool, then refrigerate for at least 2 hours (or overnight).
  8. Slice into squares. Top each with a dollop of Cool Whip, lime zest, and a lime slice before serving.

Notes

  • Substitute lemon juice for a lemon version.
  • Sprinkle shredded coconut into the crust or on top for a tropical variation.
  • Use vanilla wafers in place of graham crackers for a different crust flavor.
  • Use homemade whipped cream if preferred.
  • Store bars and toppings separately if making ahead.
