Preheat oven to 350°F. Prepare two baking sheets with silicone mats or parchment paper.
Place the butter and brown sugar in the bowl of a stand mixer. Beat on high until creamy, about 3–4 minutes. Beat in the corn syrup, egg, and vanilla just until combined.
In a large bowl, combine the flour, baking soda, and salt. With the mixer on low, carefully add the flour mixture and beat until just combined.
Stir in the chocolate chips and orange zest.
Drop dough by heaping tablespoons onto the baking sheets.
Bake the cookies for 9–11 minutes or until lightly browned. Let cool for 2 minutes on the baking sheet before removing and placing on a wire rack to cool.
Notes
Use a cookie scoop or ice cream scoop to scoop the dough—it keeps the cookies uniform in size and eliminates mess.
