Mix together the following:
9 cups flour (I used all whole wheat)
2 1/2 cups sugar
1 1/8 cup dry milk powder
3 Tbsp baking powder
1 Tbsp baking soda
1 Tbsp salt
1 Tbsp ground cinnamon
1 1/2 tsp ground nutmeg
2 1/2 cup dried butter powder
1 cup dried egg powder
Put 2 3/4 cups mixture in quart baggie and store in the refrigerator (the master mix will make 5 mixes). Since the chocolate chip-fudge muffins only had dry ingredients I added the ingredients into one baggie with the mix so it would be ready when I wanted it.
To make muffins:
Add 1 1/2 cups water
1 1/2 tsp vanilla
If dried butter or eggs weren't added to mix add 1/2 cup butter and 3 eggs.
