04 - In a separate bowl, whisk together flour, baking soda, and salt. Gradually fold dry mixture into wet ingredients until just combined. Do not overmix.
05 - Scoop tablespoon-sized portions of dough onto prepared baking sheets, spacing 2 inches apart. Flatten each portion slightly with your hand.
06 - Bake for 10 to 12 minutes until edges are set but centers remain soft. Transfer to wire rack and cool completely.
