Perfect Pancakes

I mix up this pancake mix and store it in the fridge. We eat a lot of pancakes, and this will last about a month's worth.
3 Cups all purpose flour
3 teaspoons baking soda
4 1/2 teaspoons baking powder
1 1/2 teaspoons salt
1 tablespoon sugar
2 cups whole wheat or oat flour
1 cup seven whole grain cereal
1 cup cornmeal
4 tablespoons wheat germ

Store all in airtight container and store in the fridge.
to use for pancakes:
1 egg
1/2 cup yogurt or sour cream or milk (we like sour cream the best, its the thickest, makes really fat pancakes)
1/2 cup pancake mix
I usually triple this recipe.
