To make cookies: Preheat oven to 375°. Line two baking sheets with parchment paper; set aside.
In a small bowl, whisk together flour and baking soda; set aside.
In a large mixing bowl, beat together the butter, shortening, and sugars until fluffy. Add in egg, salt, and vanilla, until thoroughly mixed.
Add in flour mixture, stirring until combined. Stir in chocolate chips.
Drop tablespoon-sized balls of dough onto prepared baking sheets, about 2 inches apart. Bake 8-10 minutes until edges are lightly browned. Let cool on baking sheet for 5 minutes, then transfer to a wire rack to cool completely.
