In large mixing bowl, cream together butter and sugars. Add eggs and vanilla and combine. Set aside.
In another bowl, combine oatmeal, flour, baking soda and salt. Gradually add this dry ingredient combination to the butter/sugar mixture. Mixture will will be thick. Lastly, fold in white chocolate chips and cranberries.
By the teaspoonful, drop cookie batter on to an ungreased cookie sheet. (About a dozen per cookie sheet.) Bake at 350 degrees for 10-12 minutes or until golden brown. Let cool on sheet for a couple minutes and transfer cookies to a cooling rack.
Notes
This recipe will yield approximately 3 1/2 dozen cookies.Storage: Store the cooled cookies in an airtight container at room temperature. Cookies will keep for 5-7 days at room temperature.Freezing: Store cookies in a freezer bag or container. Separate with parchment paper or waxed paper to prevent cookies from sticking together. Will keep frozen for up to 3 months.Notes on Butter: Feel free to use salted or unsalted butter. I prefer using salted butter, as it lends to the flavor of the cookies and helps balance the sweetness. If you prefer to use unsalted butter (or that's just what you have), increase the salt from 1/2 teaspoon to 1 teaspoon.
