Preheat your oven to 350°F (175°C). Line an 8x8 inch baking pan with parchment paper, allowing some overhang for easy removal later.
In a medium bowl, combine the graham cracker crumbs, melted butter, and granulated sugar. Mix until the crumbs are evenly coated and the texture resembles damp sand.
Press the mixture firmly and evenly into the bottom of the prepared pan to form the crust. Use the back of a measuring cup for uniformity.
Bake the crust in the preheated oven for 8 minutes. Remove from the oven and allow it to cool slightly while you prepare the filling.
In a large bowl, whisk together the sweetened condensed milk, key lime juice, key lime zest, Greek yogurt, and egg whites until smooth and well combined.
Pour the filling over the pre-baked crust, spreading it evenly with a spatula.
Bake the bars in the oven at 350°F (175°C) for 15–17 minutes, or until the filling is just set. It should jiggle slightly but not look liquid in the center.
Remove from the oven and let the bars cool to room temperature. Then transfer the pan to the refrigerator to chill for at least 2 hours, or until fully set.
Once chilled, gently lift the bars out of the pan using the parchment paper overhang. Slice into 12 squares using a sharp knife, wiping the blade clean between cuts for neat edges.
Optional: Garnish with additional lime zest or a dollop of whipped topping before serving.
