  3. In a large mixing bowl beat melted butter with both sugars and vanilla.
  4. Add in egg; beat until combined.
  5. In a small bowl mix together the flour, salt and oatmeal; add to the butter mixture; mix well to combine (the dough will be loose!).

  7. Spread out on top of the parchment paper to about 1/2-inch thick (or as best and as thin as you can).
