Raisin Bran Banana Muffins

Everyone needs more recipes for using up over-ripe bananas. I tried this one the other day and we loved it. They're healthier than the average muffin with the fruit and fiber in them.

2 Cups Raisin Bran Cereal
1 1/4 Cups All-Purpose Flour
1/2 Cup Sugar
1/4 Cup Walnuts, chopped
1 1/4 teaspoons Baking Soda
1/2 teaspoon Salt
1 Egg
1 Cup Buttermilk
1/4 Cup Cooking Oil

1. Preheat oven to 375 degrees.
2. In a large mixing bowl, stir together the cereal, flour, sugar, walnuts, baking soda and salt.
3. Break the egg into another bowl and beat it together with the buttermilk and oil.
4. Mix the wet and dry ingredients together.
5. Fill greased muffin tins 3/4 full with mixture.
6. Bake about 20-25 minutes.
