Preheat the oven to 350 degrees F. Line a baking sheet with parchment paper.
Cream together the butter and sugars in a mixing bowl, mixing until pale yellow and light and fluffy, about 3 minutes. Mix in the eggs one at a time, and then the vanilla until combined.
Whisk together the flour, baking powder, baking soda and salt in a separate mixing bowl. Slowly incorporate the dry ingredients into the wet ingredients. Stir in the chocolate chips. Portion 2 tablespoons of dough for each cookie and roll together to form a ball, spacing the dough balls 2 inches apart on the baking sheet.
Bake until the edges just start to brown, 12 to 14 minutes. Transfer to a wire rack to cool.
