Preheat the oven to 325°. Line a 9-by-13-inch baking pan with foil. In the top of a double boiler or in a microwave-safe bowl, melt the chocolate with the butter. Stir well and let cool.
Spread the coconut on a rimmed baking sheet in a thin layer and toast in the oven for about 7 minutes, until light brown and fragrant. Season the coconut with 1/2 teaspoon of the salt.
Meanwhile, in a large bowl, beat the eggs with the sugar. Using a rubber spatula, gently fold in the cooled chocolate mixture. Sift the flour, cocoa powder and the remaining 1/2 teaspoon of salt over the mixture and stir until incorporated. Pour the batter into the prepared pan and bake for about 20 minutes, or until a tester inserted in the center comes out with fudgy crumbs attached. Transfer the pan to a rack and let the brownies cool completely.
In a microwave-safe bowl, heat the dulce de leche in the microwave until bubbling. Drizzle the hot dulce de leche over the brownies and sprinkle evenly with the toasted coconut. Let cool.
