banana oatmeal muffins

1.5 cups flour
1 cup oats (I used quick cooking)
1/3 cup white sugar
1/3 cup brown sugar
2 tsp baking powder
1 tsp baking soda
1/2 tsp salt
2 eggs
3/4 cup milk
1/3 cup melted butter
4 bananas (mashed)
1 cup chocolate chips

Combine butter, milk, eggs and mashed bananas, mix throughly.  Add sugars, mix well again.  Add dry ingredients (flour, oats, baking powder, baking soda, salt), mix until just throughly wet.  Stir in chocolate chips and pour into muffin tins (this filled 15 muffins), bake at 350 ~20-25 mins
