Preheat the oven to 350°F.
Use an electric hand mixer to cream the butter and sugars together in a large mixing bowl. Mix the ingredients together on medium speed for 3 minutes, or until smooth and creamy.
Once the butter and sugars are creamed together, add the eggs and vanilla to the mixing bowl. Keep the hand mixer on a medium speed and whisk in the eggs until combined.
Sprinkle in the baking powder, baking soda, and flour. Then mix on medium-high speed. Mix until just combined and there are no clumps of flour in the cookie dough.
Use a large spoon or spatula to fold in the chocolate chips until they are evenly distributed, if you are using a stand mixer you can add them to the bowl and run the stand mixer for a moment until they are combined in.
Spread the cookie dough out in a 9x13 inch baking sheet. Bake your sheet pan cookies for 20 minutes, or until the edges begin to turn golden brown..
Remove the pan from the oven and allow the cookies to cool in the pan on a cooling rack or trivet for 15-30 minutes before slicing them.
Serve and enjoy!
