Preheat the oven to 350°F. Grease and line a 9x9-inch baking pan with parchment paper.
Place the butter in a large skillet and melt it over medium heat. Cook until the milk solids in the butter begin to brown. Transfer the butter to a large mixing bowl and let it cool for 5 minutes.
Add the granulated sugar and brown sugar to the butter and whisk until the mixture lightens in color. Stir in the eggs and vanilla extract. Mix in the all-purpose flour and salt. Fold in the white chocolate. Pour the batter into your prepared baking pan and spread evenly.
Bake for 30 to 35 minutes, until golden brown.
Allow the blondies to cool completely. Cut into squares and enjoy.
Notes
Can I add nuts to the batter? Yes. If you’d like to add nuts, go for it. Chopped walnuts, pecans, or almonds all work great. Toffee pieces or caramel bits are also delicious additions if you want an extra layer of sweetness.How do I know when the blondies are done baking? Insert a toothpick into the center—if it comes out mostly clean with just a few crumbs, they’re done. Be careful not to overbake, as blondies can dry out quickly.Do I have to add the chocolate chunks? No. The chocolate chunks are optional, and the blondies will still taste amazing without them.Do they reheat well? Yes. If you prefer them warm, microwave individual bars for 10–15 seconds to recreate that fresh-from-the-oven feel. Just be careful not to overheat them or they’ll dry out.
