soc.culture.turkish/Aysen Eren-Aksoy (1996)

2 cups sugar
1/2 cup shortening
2 eggs
2 tsp. baking soda
1/2 cup sour milk
1/2 cup cocoa
2 cups flour
1 tsp. vanilla
1 cup boiling water

Cream sugar, shortening, and 1 egg (save white from second egg for frosting). Add baking soda and milk. Then add dry ingredients, cocoa and flour. Add vanilla and boiling water. Beat on medium speed for 2 min. Bake at 375 degrees for 30 min.

Frosting
1 lb powdered sugar
1/2 cup shortening
1/2 cup peanut butter
1 tsp. vanilla
1 egg white (pasteurized or reconstituted powder)
Milk (enough to make a creamy frosting)

Put powdered sugar, shortening, peanut butter, vanilla, and egg white in a bowl. You can mix by hand or by mixer on medium speed. As you start mixing, start adding milk a little at a time. When your frosting is creamy but not too stiff, your frosting is done.

Spread on cooled cake. If cake is still warm to touch, don't put frosting on because it will warm up the frosting and start sliding off the cake.
