Zesty Key Lime Bars with a Refreshing Lime Twist

Preheat your oven to 350°F (175°C). Grease a 9x9-inch baking pan with butter or line it with parchment paper.
In a medium bowl, combine the graham cracker crumbs, granulated sugar, and melted butter. Stir until well combined. Press the mixture evenly into the bottom of the prepared baking pan to form a crust. Bake for 8-10 minutes until golden and slightly crisp. Remove from the oven and set aside to cool.
In a separate bowl, whisk together the sweetened condensed milk, lime juice, lime zest, and egg yolks. If you want a slightly thicker filling, add the tablespoon of flour and whisk again.
Pour the lime mixture over the cooled crust. Bake for an additional 15-20 minutes, or until the filling is set and slightly jiggly in the center.
Allow the key lime bars to cool completely in the pan on a wire rack. Once cooled, refrigerate for at least 2 hours before slicing.
Once chilled, slice the bars into squares. Garnish each with a lime slice and a light dusting of lime zest before serving.
