Sift flour before measuring. In a small bowl, combine flour, baking soda and salt.
Layer 1/2 the flour mixture in the bottom of a 1-quart canning jar, then add oats to the jar. Continue layering the remaining ingredients: flour mixture, granulated sugar, brown sugar (tamp tightly), dried cranberries, white chocolate baking chips, and chopped nuts.
Seal the jar, print and attach a printable gift tag. Or, hand-write recipe tag from the recipe below.
Preheat oven to 350°F. Grease cookie sheet or line with parchment paper.
In a medium bowl, beat together 1/2 cup softened butter, 1 egg and 1 teaspoon vanilla until fluffy. Add contents of jar, and mix until well blended.
Drop rounded tablespoons onto the prepared cookie sheet. Bake for 8 to 10 minutes, until edges start to brown.
Cool on wire rack.
Makes 18-24 cookies.
