Method
- Step 1: Preheat oven to 325°F (163°C) and line 2-3 large baking sheets with parchment paper, spacing cookies well.
- Step 2: In a medium bowl, whisk together flour, cornstarch, baking soda, and salt until well combined.
- Step 3: In a large bowl, beat softened butter with brown and granulated sugars on medium-high speed for about 2 minutes until creamy and fluffy.
- Step 4: Beat in the large egg, egg yolk, and vanilla extract until fully incorporated.
- Step 5: Gradually add the dry ingredients on low speed, mixing just until combined. Avoid overmixing.
- Step 6: Fold in the chocolate chips by hand using a spatula to evenly distribute.
- Step 7: Divide dough into 6 equal portions (~½ cup each), roll into balls, and gently flatten into thick discs. Place 2-3 cookies per baking sheet, spaced at least 6 inches apart.
- Step 8: Bake for 20-25 minutes until edges are lightly golden and tops look set but centers remain soft.
- Step 9: Cool cookies on baking sheets for 15 minutes before transferring to a wire rack to cool completely.
Notes
Store cookies in an airtight container at room temperature up to 4-5 days. Add a slice of bread to keep them soft. Freeze tightly wrapped cookies up to 3 months. Dough can be chilled or frozen before baking to improve texture and flavor.
