1 c. butter, melted
1 1/2 c. brown sugar, packed
2 1/4 c. rolled oats
1/2 tsp. salt
1 tbsp. molasses (if desired)
3 tbsp. flour
1 egg, slightly beaten
1 tsp. vanilla

Add sugar to butter; pour over rolled oats. Let stand at room temperature overnight so oats absorb butter.

Heat oven to 375 degrees. Mix remaining ingredients into oats. Drop level teaspoonfuls of dough 2 inches apart in heavily greased baking sheet. Bake only 12 cookies on a sheet. Bake 5 to 7 minutes, or until brown around edges. Allow to remain on sheet a few minutes until firm, then immediately remove with spatula to cooling rack. Makes 6 dozen cookies.

Note: Do not make these cookies in hot, humid weather, as cookies absorb moisture from air and become limp.
