Ingredients Method Notes

Ingredients
  

  • Ingredients You’ll Need
  • For the Crust
  • 15 full graham cracker sheets about 30 squares
  • 2 tablespoons granulated sugar
  • Pinch of salt
  • 6 tablespoons unsalted butter melted
  • For the Filling
  • 6 ounces cream cheese softened
  • 1 can 14 ounces sweetened condensed milk
  • 4 large egg yolks
  • 1 tablespoon fresh lime zest
  • ½ cup key lime juice regular lime juice works too
  • ½ teaspoon vanilla extract

Method
 

Step 1: Prep the Pan

Preheat your oven to 350°F (175°C). Line a 9×9-inch baking pan with parchment paper or foil, leaving extra hanging over the sides. This makes lifting and slicing way easier later.

    Step 2: Make the Crust

    Crush the graham crackers into fine crumbs using a food processor or by sealing them in a bag and rolling over them. Transfer crumbs to a bowl, then stir in sugar, salt, and melted butter until everything looks evenly coated. Press the mixture firmly into the bottom of your prepared pan. Press hard—this keeps the crust from crumbling later. Bake for 10 minutes, then remove from the oven.

      Step 3: Mix the Filling

      In a large bowl, beat the softened cream cheese until completely smooth—no lumps allowed. Add the sweetened condensed milk and mix until silky. Add the egg yolks one at a time, mixing after each addition. Stir in lime zest, lime juice, and vanilla extract until fully combined.

        Step 4: Bake the Bars

        Pour the filling over the warm crust and spread it evenly. Bake for 15–18 minutes, just until the center is set. Don’t let the top brown—these bars should stay pale and creamy.

          Step 5: Chill & Slice

          Let the bars cool at room temperature, then refrigerate for at least 2–4 hours. Once fully chilled, lift them out using the parchment and slice into squares.

            Expert Tips for Perfect Bars

            • Don’t overbake—the center should still have a slight jiggle

            Frequently Asked Questions

            Can I use regular limes instead of key limes?

            How do I know when the bars are done baking?
             The edges should look set, and the center should have a slight wobble when gently shaken.

             Absolutely. These bars actually taste better after chilling, making them perfect for prepping in advance.
