Beat butter and sugars.
Add egg and vanilla.
Add dry ingredients.
Fold in chips.
Measure out 6 ounce mounds and shape into 2 pretty even ball-bottom should be pressed into a slight disk and then I did a round ball on top. Freeze until solid.
Bake on parchment lined jellyroll pan at 400 degrees for 12-16mins.
Should be slightly underdone as they will cook more as they cool on cookie sheets.
