Step 1: Preheat your oven to 350°F (175°C). Grease your 9x9 inch baking pan or line it with parchment paper for easy removal.
Step 2: In a microwave-safe bowl, melt the unsalted butter until it's completely liquid. Allow it to cool slightly before adding to the other ingredients.
Step 3: In a mixing bowl, combine the melted butter and packed light brown sugar. Whisk together until smooth. Add the egg and vanilla extract, mixing until fully incorporated.
Step 4: In a separate bowl, whisk together the all-purpose flour and salt. Gradually add this mixture to the wet ingredients, stirring until just combined.
Step 5: Gently fold in the sweetened shredded coconut and white chocolate chips. Be careful not to overmix; you want to keep that lovely chewy texture.
Step 6: Pour the batter into the prepared baking pan, spreading it evenly. Bake in the preheated oven for 20-25 minutes, or until the edges are golden and a toothpick inserted into the center comes out with a few moist crumbs.
Step 7: Once baked, remove from the oven and allow the blondies to cool in the pan for about 10 minutes. While they cool, melt the semi-sweet chocolate chips in the microwave. Drizzle the melted chocolate over the top of the blondies for an extra touch of indulgence.
Step 8: Once fully cooled, use the parchment paper to lift the blondies out of the pan. Cut them into squares and enjoy!
