Preparation Steps

• Preheat oven to 350°F (175°C). Line an 8x8 inch baking pan with parchment paper, leaving an overhang on the sides.
• In a medium bowl, combine graham cracker crumbs, melted butter, and granulated sugar for the crust. Mix until well combined.

• Press the crumb mixture evenly into the bottom of the prepared baking pan to form the crust.
• Bake the crust for 10 minutes. Remove from oven and let cool slightly while you prepare the filling.
• In a separate bowl, whisk together the egg yolks, sweetened condensed milk, key lime juice, and lime zest until smooth.

• Pour the filling over the baked crust. Spread evenly.
• Bake for another 15-18 minutes, or until the filling is set but still has a slight jiggle in the center.
• Let the bars cool completely at room temperature, then refrigerate for at least 2 hours, or until firm.
• Use the parchment paper overhang to lift the bars out of the pan. Cut into bars.
• Serve chilled, topped with whipped cream and lime slices if desired.
