Preheat oven to 375 degrees.
In a large bowl, mix together the flour, baking soda, and salt. Whisk to combine.
Beat the butter and sugar together in a mix until well blended. Add eggs, one at a time until combined. Add vanilla and milk.
Slowly add the flour mixture on a low speed setting. Mix until just combined.
Fold in cranberries and white chocolate chips.
Drop large spoonfuls of cookie dough onto parchment or silpat lined cookie sheets.
Bake 13-15 minutes. Let rest two minutes on cookie sheet, then transfer to cooling racks.
(I bake two racks at a time and use my convection oven setting. Halfway through I switch the trays so they bake evenly.)
