Equipment

  • 8 inch square pan

Ingredients
 
 

For the Crust:

  • 7 tablespoons unsalted butter melted
  • 1 ½ cups graham crackers or digestive biscuits crumbs
  • 2 tablespoons granulated white sugar optional

For the Filling:

  • 1 14oz sweetened condensed milk can
  • 3 egg yolks
  • cup freshly squeezed lime juice
  • Zest of 2 limes
  • ¼ teaspoon kosher salt

Instructions
 

  • Pre-heat your oven to 350F. Butter and Line an 8*8 inch square pan with parchment paper, leaving a 2 inch overhang on the sides and set aside.
  • In a large bowl combine your melted butter, graham crackers crumbs and sugar (if using) and mix until they resemble wet sand.
  • Press the crumbs evenly into your prepared pan using a mug or a measuring cup.
  • Bake the crust for 10 minutes.
  • While the crust is baking in another large bowl, combine the condensed milk, egg yolks, lime juice, lime zest and salt until mixed well.
  • Pour the prepared filling over the baked crust making sure its evenly spread.
  • Bake the bars at 350F for 15-20 mins until the bars are set. The bars are done when the sides are set but center is slightly jiggly.
  • Let the bars cool completely in the pan on a wire rack and refrigerate for 1-2 hours before cutting then into squares using a sharp knife. Enjoy

Notes

  • Don’t Skip the Zest: Lime zest adds concentrated citrus flavor. Use a microplane to get fine zest without the bitter white pith.
  • Room Temperature Ingredients: Make sure the egg yolks and condensed milk are at room temperature before mixing. This helps the filling blend smoothly and evenly.
  • Avoid Overbaking: The filling should be just set with a slight jiggle in the center. Overbaking can cause the bars to crack or become rubbery.
  • Chill Before Slicing: Let the bars cool completely, then refrigerate for at least 2 hours before cutting. This helps the filling set and makes slicing easier.
