Mix the dry ingredients together in a stand mixer to combine.
Cut up cold butter and add to dry ingredients. Mix quickly to combine (should resemble a coarse meal)
Add the buttermilk and eggs and mix until combined.Add white chocolate and cranberries and mix quickly. You do not want to overwork the dough, just a couple quick pulses will do.
Scoop out the dough into even portions. I have an extra large ice cream scoop that I like to use. It allows then equal sizes.
Place dough onto a parchment lined cookie sheet and bake in a 375 degree oven for 14-16 minutes. Place on a rack to cool. Enjoy!
