Preheat oven to 350 degrees F. Prepare baking pan.
Cream together the butter, sugar, and brown sugar with an electric mixer. Add eggs one at a time and mix in.
Sift together the flour, old fashion oats, baking soda, cinnamon, and salt add to the creamed mixture and mix in.
Mix in the zucchini, pecans, and dried cranberries until well blended.
Scoop with a teaspoon. Make the scoops well rounded. Place on prepared cookie sheets and place in the preheated oven. Bake 12 to 14 minutes or until they are lightly browned.
Remove from the oven and cool on cooling racks until completely cooled. These cookies freeze well.
Notes
Make sure to squeeze as much liquid as you can from the shredded zucchini before adding it to the cookie dough.
