I found the following recipe in this board, but in the directions it mentions to add eggs, but there aren't any eggs in the ingredients list. Would whoever posted it please correct me?

Chocolate Mint Wafers

 1/4 cup heavy cream

 1 tablespoon vinegar

 1/2 cup shortening

 1 cup sugar

 1/8 teaspoon peppermint extract

 2 cups sifted flour

 3/4 cup cocoa

 1/2 teaspoon baking soda

 1/4 teaspoon salt

Combine heavy cream and vinegar in measuring cup; set aside.

Cream together shortening and sugar; stir in egg and peppermint extract.

Sift together remaining dry ingredients; add alternately with heavy cream to creamed mixture. Mix thoroughly.

Divide dough in half and shape into two rolls. Wrap tightly in waxed paper and chill several hours in refrigerator.

Cut dough in 1/8 inch slices with sharp knife; place 1 1/2 inches apart on ungreased baking sheet. Bake in 350 degree oven 15 minutes.

Remove cookies and cool on wire racks.

Makes 3 dozen cookies
