Whisk the melted butter and sugar vigorously for one minute. Add eggs, water, and vanilla extract, whisking again for about 30 seconds. Tap excess batter off the whisk and set it aside.

Sprinkle cocoa powder, powdered sugar, flour, and salt over the wet ingredients. Use a rubber or silicone spatula to stir the mixture until it is glossy and well combined. Stir in the chocolate chips.

Pour the batter into the prepared pan and smooth the top. Bake for 18-20 minutes, until a toothpick inserted into the center comes out with moist crumbs but no raw batter. Remove from the oven and place on a cooling rack. Allow the brownies to cool completely.

In a medium saucepan over medium-low heat, combine evaporated milk, brown sugar, egg yolks, butter, and salt. While whisking constantly, slowly bring to a gentle simmer. Continue whisking for 3-4 minutes until the sugar has dissolved and the mixture thickens slightly. Remove from heat and stir in vanilla, pecans, and coconut.

Spread the topping evenly over the cooled brownies. Sprinkle with flaky sea salt if desired and let the topping firm up before cutting. For quicker results, refrigerate the brownies. Serve at room temperature.
