Copycat Starbucks Chocolate Chunk Cookies

Preheat oven to 375°. As it heats, cream the butter and both types of sugar together until light and fluffy, 2 to 3 minutes. Add egg and vanilla, beating to combine. In a separate bowl, combine flour, baking soda, and salt. Slowly mix in flour mixture, then fold in chocolate chunks. Roll into 1 1/2" balls, placing them about 2 inches apart on a parchment-lined baking sheet. Top each cookie with a few extra chocolate chunks, for presentation's sake, and bake for 8 to 10 minutes, or until the cookie is lightly golden and no longer gooey in the center.
