In a large bowl, beat together the butter, brown & granulated sugars, vanilla, baking powder & soda, eggs
Stir in the baking chips
Stir in the flour
Split the dough in half & form two logs (roughly 2 inches wide) on plastic wrap & wrap up tightly
Place in the refrigerator & chill for roughly an hour
Preheat oven to 350 degrees, place baking rack 1 level above the middle
Slice the chilled cookie dough logs into half inch thick slices & place on baking sheet lined with parchment paper
Bake for 8-10 minutes (I baked mine for exactly 9 minutes but all ovens are different so check at the 8 minute mark, be careful to not over bake)
Remove when done & transfer cookies to a cooling rack after resting on the pan for 1-2 minutes
I prefer to make logs out of the dough for several reasons. I can slice them however thick I want. I also find it so much easier & faster then scooping out one by one onto the baking sheet. I think the best reason for doing this is I can stick one in the freezer for a later time. This is nice for when I want to make homemade cookies but don't want to start from the beginning or if I don't want tons of cookies sitting around tempting me to eat, eat, eat. I can just pull the dough out of the freezer, slice, and bake whenever I am in the mood for cookies.
