Ingredients

Scale

Key Ingredients:

  • 1 can (14 ounces / 396 grams) sweetened condensed milk
  • 4 large egg yolks
  • ½ cup (120 milliliters) key lime juice

Crust Ingredients:

  • 1 ½ cups (180 grams) graham cracker crumbs
  • ¼ cup (50 grams) granulated sugar
  • 6 tablespoons (85 grams) unsalted butter, melted

Garnish Ingredients:

  • 1 tablespoon lime zest
  • Powdered sugar
  • Whipped cream
  • Lime slices (optional)

Instructions

  1. Prepare the oven by setting the temperature to 350°F (175°C), ensuring an optimal baking environment.
  2. Create a convenient lifting mechanism for the bars by lining a 9×9-inch baking pan with parchment paper, allowing extra material to hang over the edges.
  3. Craft the crust by thoroughly blending graham cracker crumbs, granulated sugar, and melted butter into a cohesive, slightly moistened mixture.
  4. Transform the crumb mixture into a uniform base by pressing it evenly and firmly across the bottom of the prepared pan, creating a compact foundation.
  5. Initiate the crust’s initial cooking phase by placing the pan in the preheated oven and baking for approximately 8-10 minutes, watching for a delicate golden hue to develop.
  6. Remove the crust from the oven and allow it to cool momentarily, establishing a stable platform for the subsequent layers of the key lime bars.

Notes

  • Swap graham crackers with gluten-free alternatives like almond flour or gluten-free cookie crumbs for celiac or gluten-sensitive diets.
  • For a richer crust, add finely chopped toasted nuts like pecans or almonds to enhance the texture and bring deeper nutty undertones.
  • Ensure butter is completely melted and evenly mixed to create a uniform, compact crust that holds together without crumbling when sliced.
  • Use room temperature eggs and fresh key lime juice for the most vibrant, tangy flavor that makes these bars truly zesty and bright.
