1/2 cup unsalted butter
1 cup firmly packed brown sugar
1 tablespoon vanilla extract
4 tablespoons flour
2 tablespoons milk
1 cup old-fashioned rolled oats

Preheat oven to 350°F. Grease and flour 2 baking sheets.

Cream butter and sugar. Add vanilla; stir in flour, milk, and rolled oats. Drop batter by the tablespoon onto prepared baking sheets; allow room for cookies to spread to about 3-inches in diameter. Each baking sheet will hold about 6 cookies.

Bake until cookies flatten and look dry (10 minutes). Let cookies cool for 4 to 5 minutes on baking sheets. Lift from baking sheet with a metal spatula and cool completely.

Makes 2 dozen cookies.
