1-1/2 cup brown sugar (packed)
2-1/4 cup rolled oats
1/2 teaspoon salt
1 tablespoon molasses
3 tablespoons flour
1 egg, slightly beaten
1 teaspoon vanilla
Preheat oven to 375 degrees. Add sugar to butter; pour over rolled oats. Stir well. Let stand at room temperature overnight so that the oats absorb the butter.
Mix remaining ingredients into oats. Drop level teaspoonfuls of dough 2 inches apart on heavily greased baking sheet. Put 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.
