The mixing order on this cookie is also unique!
Mix butter just to break it down.
Add sugars and mix just to combine-not cream.
Add both white chocolates and mix.
Add all the dry ingredients and stir, including sprinkles.
Mix eggs and vanilla in a bowl and add last just until dough all comes together in mixer.
Weigh out balls of 125 grams and press down to form disks. (Otherwise mine did not spread enough).
Preheat a jellyroll pan at 350 for 5 minutes.
Remove and place cookies directly on pan -NO parchment.
Bake 14 mins, remove and cool on pan a few minutes.
(Update: I now like to bake these for 13 mins at 400)
