I always use Kosher salt in my kitchen! If using table salt, start with half the amount and adjust to taste, as it is much "saltier" by volume.
Instructions
Brownie Batter
Preheat the oven to 350°F. Lightly grease a 9x13 metal baking pan.
Melt butter with sugar in a microwave safe bowl, heating in 30-second intervals until fully melted. Set aside to cool for a few minutes.
After the butter mixture has cooled slightly, whisk in eggs, egg yolk, and vanilla extract. Once fully combined stir in the cocoa powder.
Now add in the flour, salt, and cornstarch and stir until fully combined.
Spread evenly in the prepared pan. Bake for 30-35 minutes or until a toothpick inserted in the center comes out with moist crumbs attached. Let cool completely before topping.
Coconut-Pecan Topping
In a medium saucepan, combined butter, both sugars, egg yolks, and evaporated milk. Heat over medium heat, whisking constantly. Bring to a gentle boil and continue cooking until thick enough to coat a spoon.
Remove from the heat and stir in the vanilla, salt, shredded coconut, and pecans.
Spread the topping evenly over the cooled brownies. Let cool before serving. Enjoy!
Notes
Use a metal 9x13 pan for the best results; it helps the brownies bake evenly.
Don't be alarmed, this brownie batter is very thick!
If lining with parchment paper, hold it into place while spreading the thick brownies batter.
Unsweetened coconut is my preference for balance, but sweetened coconut works too.
Pecans can be toasted before adding to the filling for extra flavor.
