Refrigerator Bran Muffins

I have had a recipe similar to this with dates but this seems to be more popular and I also like that it is made with olive oil instead of shortening.

2 cups water, boiling
2 cups Kellogg’s All Bran Bran Buds
¾ cup olive oil
2 ¼ cups sugar
4 eggs
1 quart buttermilk
5 cups flour – part wheat might be good
5 t. soda
1 t. salt
4 cups All Bran

Combine bran buds and boiling water and let sit until softened.  Mix olive oil and sugar together with a mixer.  Add eggs and buttermilk.  Add softened bran mixture.  Stir in flour, soda, salt and all bran.  Place in container in refrigerator for up to a month.  To bake, place mix in muffin cups that have been sprayed with nonstick cooking spray.  Bake at 400° for 15 minutes.  They also taste delicious if you stir in extra ingredients just before you bake them, such as: diced apple, craisins, raisins, chopped nuts.
