Bran Muffins (10 servings) 1 (20 oz.) box of Bran Cereal 5 cups all-purpose flour 4 cups sugar 4 teaspoons baking soda 2 teaspoons salt 4 large eggs - beaten 1 cup oil 1 quart buttermilk 1 Tablespoon cinnamon Mix in large container with wooden spoon. Cover and refrigerate overnight. Bake at 400 for 12 to 15 minutes. You can also make bread with the batter, just use a loaf pan instead of muffin tins. Cooking time is about the same, but check it after 10 minutes. The easiest bran muffin recipe I think you'll find. You can refrigerate the mix up to 6 weeks.
