- Preheat oven to 350ºF and line two 16×11 baking sheets with parchment paper. In a small mixing bowl, stir together all-purpose flour and baking soda. In a separate medium-sized mixing bowl, use a hand-mixer on medium speed to cream together butter and sugar. Beat in soy sauce and vanilla extract. Add eggs and beat until just combined.
- Gradually beat flour mixture into wet ingredients until combined. Fold in chocolate chips. Transfer bowl to freezer for 15 minutes.
- Place rounded tablespoon-sized mounds of dough onto baking sheet 2 inches apart. Bake for 12 minutes or until edges are golden brown. Sprinkle immediately with flaky sea salt. Cool on baking pan for 10 minutes. Transfer to wire cooking rack to cool completely.
