Pies: 2 cups sugar
1 cup shortening
1 cup cocoa
2 egg yolks and 2 whole eggs (save the egg whites for the filling)
2 teaspoons vanilla
1 cup sour milk or buttermilk
2 teaspoon baking soda
1/2 teaspoon salt
4 cups flour Cream sugar and shortening together in a large bowl. Add eggs and mix. Sift dry ingredients together and add to the creamed mixture alternatively with milk. Batter will be stiff. If it is too thin, add more flour. Drop by tablespoon onto greased sheets. Bake at 350 for 8 to 10 minutes, until a toothpick inserted in the cookies comes out clean. Filling: 2 egg whites
1 box 10X sugar
1 cup shortening
4 tablespoons milk
1 teaspoon vanilla Beat egg whites till stiff. Add shortening and vanilla and blend. Add milk and then add the sugar. Beat until smooth. Spread some filling on the bottom side of one cookie; top with a second cookie. Repeat with the remaining cookies and filling. Store in the refrigerator or freezer. Yields approximately 5 dozen. Note: You can buy a powdered buttermilk mix to make your own buttermilk or you can substitute 1 cup yogurt for either the buttermilk or sour milk. To make sour milk, place 1 tablespoon lemon juice (or vinegar) and fill with milk to make 1 cup. Let stand for 5 minutes. Submitted by: kitchenpanhands |
