Ingredients, Substitutions & Foolproof Tips

  • 1 cup graham cracker crumbs (about 8 full crackers, finely crushed) – provides a crunchy base
  • ¼ cup light brown sugar – adds sweetness and depth to the crust
  • 2 tablespoons unsalted butter (melted) – brings everything together in the crust
  • 1 ¾ cups sweetened condensed milk (about 1 1/2 cans, or 21 ounces) – gives the filling a creamy sweetness
  • 6 egg yolks – helps to thicken and enrich the filling
  • 1 cup key lime juice – the star ingredient that gives bars their distinct flavor
  • 1 tablespoon fresh lime zest – for an extra layer of citrus brightness
  • 1 cup heavy cream – used for a luscious whipped topping
  • 1 tablespoon granulated sugar – sweetens the whipped cream
  • 1 teaspoon vanilla extract – enhances the flavors
  • Lime zest (for garnish, optional) – adds a pop of color and flavor for serving

Step-by-Step Directions

  1. Preheat your oven: Heat oven to 300°F. Line an 8x8x2-inch square baking pan with foil for easy removal.
  2. Make the crust: In a small bowl, stir together graham cracker crumbs, brown sugar, and melted butter until a sandy mixture forms. Press gently into the bottom of the prepared pan. Bake for 12 to 15 minutes until the crust is golden brown and set. Set aside to cool completely.
  3. Prepare the filling: In a medium mixing bowl, whisk together sweetened condensed milk, egg yolks, lime juice, and lime zest until well combined. Pour this mixture carefully and evenly over the cooled crust.
  4. Bake the filling: Bake at 300°F for 30 to 40 minutes. The filling should be slightly jiggly but the center set. Transfer the pan to a cooling rack to cool completely, about 2 hours.
  5. Make the topping: In a medium bowl using an electric hand mixer, beat heavy cream, sugar, and vanilla on medium-high speed until stiff peaks form. Spread the whipped cream evenly over the cooled bars and sprinkle with lime zest if desired. Cover and refrigerate for at least 2 hours before slicing and serving. Use the foil to help remove the bars from the pan for easy slicing.

Common Mistakes to Avoid & Pro Tips

  • Overbaking: This can lead to a dry filling. Look for a slight jiggle in the center.
  • Not allowing the crust to cool: If the crust is hot, it can affect the filling layer.
  • Tip: Use fresh key limes for the best flavor.
  • Tip: If you prefer a sweeter whipped cream, adjust sugar to taste.
