Preheat your oven to 175°C (350°F). Grease and line a 9x9-inch (23x23 cm) baking pan with parchment paper, leaving some overhang for easy removal later.
In a medium bowl, cream together the softened butter and granulated sugar until smooth and fluffy. Gradually mix in the flour until a dough forms.
Press the dough evenly into the bottom of the prepared pan to form the crust. Use the back of a spoon or your fingertips to press it down firmly.
Bake the crust in the preheated oven for 15 minutes, or until lightly golden around the edges. Remove from the oven and allow to cool slightly while preparing the filling.
In a separate bowl, whisk together the egg yolks, sweetened condensed milk, key lime juice, and lime zest until smooth and well combined.
Pour the lime filling onto the slightly cooled crust, spreading it evenly with a spatula.
Return the pan to the oven and bake for an additional 20 minutes, or until the filling is set and does not jiggle when shaken.
Remove from the oven and let the bars cool completely to room temperature. Then, refrigerate for at least 2 hours (or overnight) to firm up the filling.
Once chilled, use the parchment paper overhang to lift the bars out of the pan. Dust the top with powdered sugar for an elegant finish.
Cut into 12 squares or bars and serve chilled. Store leftovers in the refrigerator for up to 3 days.
