Instructions
Crust
Heat the oven to 350°F. Prepare a 9x9" baking pan by lining it with parchment paper (cut the paper about 4 inches larger than the bottom of the pan, crease the paper where the edges of the pan will be, and cut vertical slits in each of the 4 corners of the paper).
Add 1 cup all-purpose flour, 1/2 cup pecan halves, 2 Tablespoons brown sugar, and 1/4 teaspoon salt to the bowl of a food processor or mini food processor. Process until the mixture resembles coarse sand. Add the cubed butter and pulse the food processor again, until the mixture resembles damp coarse sand.
Press the pecan mixture firmly into the parchment-lined baking pan, ensuring that the crust will be of even thickness and that it reaches into the corners. Bake the crust for about 20 minutes until it becomes fragrant and slightly browned.
Coconut Filling
While you're waiting for the crust to bake, start preparing the filling. Using a hand mixer or a stand mixer, beat together 1/2 cup brown sugar, 1/4 cup light corn syrup, 1 large egg, the melted butter, 1 teaspoon vanilla extract, and 1/4 teaspoon salt until the mixture appears pale and foamy. Fold in 1 cup unsweetened shredded coconut and 1/4 cup chocolate chips with a spatula.
Pour the coconut filling mixture onto the pre-cooked crust, smoothing the top and making sure the filling reaches the corners of the pan. Bake for 25-30 minutes, until the filling appears golden brown on top and the edges of the squares are set but the filling still jiggles when gently shaken. Set the pan on a cooling rack and cool completely to room temperature, about 2 hours. If you need your squares to cool faster, put the pan in the fridge for about an hour, or the freezer for 15-30 minutes.
If desired, melt about 2-4 Tablespoons of dark, milk, and/or white chocolate to drizzle over the top of your cooked squares (you can drizzle using a spoon or spatula, or, for the most control, use a squeeze bottle or piping bag). Let the chocolate set before cutting.
Carefully lift the parchment paper out of the pan and move to a cutting board. Cut the squares into your desired size using a large chef's knife. Serve at room temperature, keeping any leftovers in an airtight container or zipper bag in the fridge or freezer.
