In a clean, dry quart-size mason jar add the dry ingredients in the order listed (flour, soda, salt, sugars, oats, cranberries, white chocolate, nuts) using a large funnel and tapping the jar on the counter between each layer to settle.
Add lid to jar, print out direction tags and attach tag to the jar with ribbon or twine.
When Ready To Bake:
Preheat oven to 350 degrees. Lightly grease or line two cookie sheets.
In a large bowl mix the melted butter, egg and vanilla. Add the contents of the cookie mix jar and stir well until everything is combined.
Use a small cookie scoop to portion out dough onto the prepared cookie sheets, 2 inches apart. You will need to shape the dough a bit, pressing the fruit, nuts and chips into the dough and making small round balls.
Bake for 8-10 minutes. Remove to a wire rack to cool completely before storing in an airtight container (or freezing for longer storage).
One jar makes about 24 cookies.
Notes
The sealed cookie mix will stay fresh for 4-6 months.
