Preheat oven to 350°. Oil baking sheet. Combine milk and chocolate in top of double boiler. Place over boiling water on high heat and stir constantly until mixture thickens, about 5 minutes. Add remaining ingredients and stir to blend. Drop by teaspoonfuls onto prepared sheet and bake about 10 minutes, or until bottoms are set. (Watch carefully, these burn easily.) Do not overbake; should be soft and chewy. To cool, transfer to a plate or a rack lined with wax paper. Makes 2 to 2 1/2 dozen.
