Peppermint Patties

In a bowl, combine first four ingredients. Add milk and mix well. Roll into 1-in. balls and place on a waxed paper-lined cookie sheet. Chill for 20 minutes. Flatten with a glass to 1/4 in.; chill for 30 minutes. In a double boiler or microwave-safe bowl, melt chocolate chips and shortening. Dip patties; place on waxed paper to harden and freeze for a short while.

Makes about 5 dozen.
