Combine all and store in airtight container; give the mix with a shortbread mold.
Scottish Shortbread (16 pieces): 1 cup butter softened, 1 package shortbread mix. Preheat oven to 300ºF. Knead the butter into the shortbread mix, and press mixture firmly into an 8" pie plate, or shortbread mold. Bake for 1 hour. The shortbread should be pale in color, not browned. Cut into wedges while still warm.
