Cream the butter, brown sugar and granulated sugar until fluffy. Add the vanilla and eggs and beat for an additional 2 minutes. Add the flour, baking powder, baking soda and salt and mix until fully incorporated. Add the chocolate chips and mix until well distributed. (The cookie dough should be somewhat thick.)
Scoop up about 2 tablespoons of the dough per cookie (or use a medium cookie scoop) and plop the dough onto the baking sheets. Bake until the edges are golden brown, 12 to 14 minutes. Allow the cookies to stay on the baking sheets for an additional 2 minutes. Pick up the parchment paper with the cookies still on top and transfer to a cool non-porous surface. Allow the cookies to cool on the paper for at least 3 minutes before serving. Enjoy!
