Tips

  • Using melted butter instead of solid butter helps the sugars dissolve, bringing together all ingredients consistently.
  • When forming cookie balls, gently bring them together so they stay light and airy; do not smooth the edges. The rough edges provide extra surface area for crispiness while baking.
  • Chill the cookie dough for at least 4 hours (preferably overnight) so that the flavors can come together.
