Method
- Step 1: Preheat oven to 325°F (163°C). Line 2-3 large baking sheets with parchment paper.
- Step 2: In a medium bowl, whisk together flour, cornstarch, baking soda, and salt until evenly combined.
- Step 3: In a large bowl, beat softened butter, brown sugar, and granulated sugar on medium-high speed until creamy and well combined, about 2 minutes.
- Step 4: Add egg, egg yolk, and vanilla extract to the butter mixture. Beat until fully incorporated.
- Step 5: Gradually add dry ingredients to the wet ingredients on low speed, mixing just until combined to avoid tough cookies.
- Step 6: Fold in chocolate chips by hand until evenly distributed.
- Step 7: Divide dough into six equal portions (about ½ cup each). Roll into balls and slightly flatten tops. Place on baking sheets, leaving at least 6 inches between cookies.
- Step 8: Bake for 20-25 minutes until edges are lightly golden and centers look soft.
- Step 9: Cool cookies on baking sheets for 15 minutes to set before transferring to a wire rack to cool completely.
Notes
For softer cookies, chill dough for 30 minutes before baking. Store in an airtight container at room temperature up to 4 days or freeze for up to 3 months. Add nuts or chocolate chunks for variety. Use parchment paper or silicone mats to prevent sticking.
