Preheat your oven to 350°F (175°C). And lightly grease an 8x8-inch baking pan.
In a medium saucepan over medium heat, melt the butter. Keep a close eye on it and swirl the pan regularly to avoid burning. Once the butter takes on a beautiful amber hue and releases a nutty aroma, remove it from the heat.
Stir the brown sugar into the browned butter, mixing thoroughly until the sugar is fully dissolved. Add in the eggs and vanilla, stirring until everything is smooth and well combined.
In a separate bowl, whisk together the flour with baking powder and salt. Gradually add the dry ingredients to the wet mixture, stirring gently until just combined.
Fold in the shredded coconut to incorporate that delicious texture. Pour the batter into your prepared baking dish, spreading it evenly.
Bake in the preheated oven for 40-45 minutes. If the top starts to brown too quickly, cover it with foil for the final 10 minutes. Let the bars cool completely before slicing and serving.
