Get your ingredients out and prepped.
Hydrate the Cranberries - by pouring HOT water over the cranberries - and allow them to sit about 10 minutes.
Combine the flour, cinnamon, baking soda and salt and whisk together and set aside.
Zip up 1/2 (or more) of the oatmeal in your food processor or mini food processor. Set aside oatmeal.
In the bowl of your mixer - combine the sugar, brown sugar and butter. Cream the sugars and butter together.
Add in eggs one at a time and mix well between them.
Add in vanilla extra and mix well.
Mix in the flour mixture that was set aside - mix only till combined.
Remove the bowl from your mixer and add the oatmeal, white chocolate chips and DRAINED cranberries. Stir up the mixture - a wooden spoon or sturdy spatula works well. Make sure all is well combined.
Refrigerate the dough for at least a couple of hours - or overnight.
When ready to bake - set the oven to 350℉
Prepare your cookie sheets. One time I wrote that the refrigerated dough stuck to the cookie sheet. I therefore recommended using parchment on the cookie sheet. Either use parchment - or Grease / Butter up your cookie sheets for the first use.
Use a cookie scoop and roll 1" balls of dough. Place 12 on each cookie sheet.
Bake for 11-13 minutes depending on your oven / temp etc. Rotate cookie sheets half way through cooking time.
When cookies are golden remove and let the cookies set on the cookie sheet for 2- 3 minutes - before allowing them to cool completely on a cooling rack.
