Preheat your oven to 350°F. Lightly grease and flour an 8x8-inch baking pan, or line it with parchment paper, leaving an overhang on two sides to easily lift the blondies out later.

In a light-colored saucepan, melt the unsalted butter over medium heat. This allows you to easily see the color change.

Continue to cook the butter, stirring occasionally, until it foams, then turns a rich golden brown, and smells nutty. Be careful not to burn it; this process usually takes 5-7 minutes.

Immediately pour the brown butter into a heatproof bowl to stop the cooking process. Let it cool slightly for about 5 minutes.

In a large mixing bowl, combine the slightly cooled brown butter with the packed light brown sugar and granulated sugar. Whisk until well combined and smooth.

Add the large egg and vanilla extract to the sugar mixture. Whisk vigorously for about 1 to 2 minutes until the mixture is lightened in color and fluffy.

In a separate small bowl, whisk together the all-purpose flour, baking powder, and salt.

Gradually add the dry ingredients to the wet ingredients, mixing with a spatula or wooden spoon until just combined. Be careful not to overmix, as this can lead to tough blondies.

Gently fold in the semi-sweet chocolate chips until evenly distributed throughout the batter.

Pour the blondie batter into the prepared 8x8-inch baking pan and spread evenly with a spatula.

Bake for 20 to 25 minutes, or until the edges are set and lightly golden brown, and a toothpick inserted into the center comes out with moist crumbs attached (not wet batter). Do not overbake for moist blondies.

Remove the pan from the oven and let the blondies cool completely in the pan on a wire rack before cutting into squares. This allows them to set properly and become fudgy.
