In a bowl of an electric mixer fitted with a paddle attachment or a large bowl with a handheld electric mixer cream the butter and sugars for a minute or two, until light and fluffy.
I prefer to scoop the dough at this point but you could just cover the bowl with plastic wrap and chill. If you scoop the dough now it will be very soft, so just before baking I will reshape them and top them with more chocolate chips to make them look prettier.
