1 large egg (or two medium)
1 tsp. soda
1 tsp. baking powder
1 tbsp. vinegar
½ c. milk
1½ c. sugar
1 c. shortening
Flour (see below, but about 3 cups in the mix)

Mix all ingredients except flour. Gradually add flour until the shortening is mixed in and the dough is stiff enough to roll out. Roll on floured surface. Cut cookies out and bake at 400 degrees until brown, 10-12 minutes. Top with sprinkled sugar or icing:

Black And White cookie style frosting:

(Let cookies cool completely before starting)

4 cups confectioners' sugar
1/3 cup boiling water
1 (1 ounce) square bittersweet chocolate, chopped

Place confectioners sugar in large bowl. Mix in boiling water one tablespoon at a time until mixture is thick and spreadable. (Add more than the indicated amount if you need to).
Transfer half of the frosting to the top of a double boiler set over simmering water. Stir in the chocolate. Warm mixture, stirring frequently, until the chocolate melts. Remove from heat.
With a brush, coat half the cookie with chocolate frosting and the other half with the white frosting. Set on waxed paper until frosting hardens.
