01 - Preheat the oven to 350°F. Line an 8-inch square baking pan with parchment paper, leaving a 2-inch overhang for effortless removal.
02 - Combine graham cracker crumbs, melted butter, sweetened shredded coconut, granulated sugar, and salt in a mixing bowl. Stir until the mixture achieves the texture of wet sand.
03 - Press the crust mixture firmly and evenly into the base of the prepared pan. Bake for 10 minutes, then set aside to cool slightly.
04 - In a separate bowl, vigorously whisk together sweetened condensed milk, egg yolks, freshly squeezed lime juice, lime zest, coconut cream, all-purpose flour, and vanilla extract until completely smooth and uniform.
05 - Pour the filling over the baked crust, spreading evenly with a spatula. Bake for 18 to 20 minutes, just until the edges appear set and the center remains slightly wobbly.
06 - Allow to cool in the pan at room temperature for 1 hour. Refrigerate for a minimum of 2 hours, or until thoroughly chilled.
07 - Using the parchment overhang, lift the set bars from the pan and cut into equal portions. Top with whipped cream, toasted coconut, and extra lime zest as desired. Serve bars well-chilled.
