Preheat the oven to 350°F. Line an 8 by 8-inch metal baking pan with foil or parchment, leaving an overhang. Spray with nonstick cooking spray.

In a large bowl, combine the melted butter and light brown sugar with a rubber spatula. Add the eggs, egg yolk, and vanilla extract; stir until well incorporated.

Stir in the fine salt and all-purpose flour until a thick dough-like batter forms. Fold in 3/4 of the shredded coconut and chopped chocolate chunks.

Spread the batter evenly into the prepared pan. Sprinkle the remaining coconut and chocolate chunks over the top, pressing them slightly into the batter.

Bake for approximately 40 minutes, or until the blondies are set but still slightly gooey in the center.
06 -
Allow the blondies to cool completely before cutting into bars with a large sharp knife or plastic knife. For cleaner cuts, wipe the blade under hot running water between cuts.

Cover and store the blondies at room temperature for up to 3 days. Optionally, reheat slightly in the microwave before serving.
