04 - In a large bowl, combine browned butter, brown sugar, and granulated sugar. Mix until blended.
05 - Add eggs one at a time, beating well after each addition. Stir in vanilla extract.
06 - Gradually mix in the dry ingredients until just combined.
07 - Gently fold in white chocolate chips until evenly distributed.
08 - Scoop tablespoonfuls of dough onto prepared baking sheets, spacing about 2 inches apart.
09 - Bake for 10–12 minutes, or until edges are golden and centers are just set.
10 - Cool on the pan for 5 minutes, then transfer to a wire rack to cool completely.
