Making Coconut Lime Bars is easy and enjoyable! Follow these steps for a perfect outcome:

1. Preheat the Oven: Preheat your oven to 350°F (175°C) and grease an 8×8-inch baking dish or line it with parchment paper for easy removal.
2. Prepare the Crust: In a bowl, combine the flour and powdered sugar. Add the softened butter, mixing with your fingers or a pastry cutter until crumbly.
3. Press the Crust: Evenly press the mixture into the bottom of the prepared baking dish. Bake in the preheated oven for 15-20 minutes, or until lightly golden.
4. Make the Filling: In a separate bowl, whisk together the eggs, granulated sugar, lime juice, lime zest, shredded coconut, salt, and cornstarch until smooth and well combined.
5. Pour the Filling: Once the crust is done baking, remove it from the oven and pour the lime filling over the hot crust.
6. Bake Again: Return to the oven and bake for an additional 25-30 minutes, or until the filling is set and slightly jiggly in the center.
7. Cool Down: Let the bars cool in the pan on a wire rack for 15-20 minutes. Then, refrigerate for at least 1 hour to fully set.
8. Cut and Serve: Once cooled and set, cut into squares or bars. Dust with powdered sugar or garnish with shredded coconut and lime slices if desired.
