Zucchini Muffins

This recipe comes from the "Best-Loved Recipes Westercamp Family Cookbook".  They are from my cousin, Kate whom I have very fond memories of when we were both younger.  I babysat her during the summer months.  She is a very good cook and I knew this recipe would be a hit since it had her name on it!  :)
