Ingredients

1/2 cup butter
2 cups light brown sugar, firmly packed
1/2 cup milk (or evaporated milk)
pinch of salt
1/2 cup peanut butter
1 teaspoon vanilla extract
3 cups quick-cooking rolled oats

Directions

Line two baking sheets with waxed paper. In a large heavy saucepan combine the butter, brown sugar, milk, and salt. Bring mixture to boil over medium heat, stirring occasionally, until mixture comes to a full rolling boil. Without stirring, let mixture boil for exactly 3 minutes. Immediately remove from heat. Stir in peanut butter and vanilla, stirring until peanut butter has melted. Quickly stir in the oats, mix well. Working fast, drop mixture by tablespoonfuls onto prepared baking sheets. Allow to cool and become firm, about 30 minutes. Makes 3-4 dozen cookies.
