Ingredients:
10 cups flour
6 cups sugar
1 1/3 Tbsp. salt
5 1/2 Tbs. double acting baking powder
1 cup vegetable shortening

Preparation:

1. Combine flour, sugar, salt and baking powder. Put 2 cups of the flour mixture in a food processor together with shortening. Process until mixture is very fine.
2. Add remaining flour mixture and stir well. Divide into four equal portions (1 portion = about 4 cups). Store in covered jar in cool dry place. Store in the refrigerator for up to a month, or in the freezer for up to 3 months.

Each portion of cake mix (about 4 cups) will make two 8″ cakes or one 13×9″ cake.
