Step 1: Preheat your oven to 350°F (175°C).
Step 2: In a large mixing bowl, cream together the softened butter, light brown sugar, and granulated sugar until light and fluffy, about 2-3 minutes. Mix in corn syrup, egg, and vanilla extract until combined.
Step 3: In another bowl, whisk together all-purpose flour, baking soda, and salt until no lumps remain.
Step 4: Gradually add dry ingredients to wet mixture, stirring gently until just combined.
Step 5: Fold in chocolate chips using a silicone spatula.
Step 6: Drop rounded balls of dough onto a baking sheet lined with parchment paper, leaving about 2 inches of space between each.
Step 7: Bake for 10-12 minutes, until edges are lightly golden and centers appear slightly underbaked.
Step 8: Cool cookies on the baking sheet for 5 minutes, then transfer to a wire rack to cool completely.
