Muffins are so good in the morning with a cup of coffee, at night with a glass of milk or just anytime. These sour cream banana muffins are a great way to use up extra bananas and the chocolate chips really add to this recipe. Make these muffins for an after school snack for the kids or let the children or grandchildren help you make these banana treats. You could add raisins to these muffins if desired or you could leave out the nuts. This recipe would make a wonderful gift for a sick friend, new neighbor or give them just for a good deed.
