The recipe we use can be found at DianaDesserts.com (but we make "mini muffins", and reduce the baking temperature to 350 degrees).
I love three things about this recipe:
1) The muffins are moist and delicious.
2) It is a fun to bake them with kids. "Little hands" can fill the tins with muffin liners, mash the bananas, and add and stir the ingredients.
3) They make perfect "little treats" for school lunch boxes. (I freeze them in individual snack bags, which makes them easy to "pop" into lunches each night.)
Give them a try, and let me know what you think.
