Copycat Starbucks Chocolate Chunk Cookies

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