While looking for a muffin recipe, I came across this one which claims to be low fat. http://www.food.com/recipe/banana-chocolate-chip-muffins-19424.
My oldest daughter cannot eat dairy, so I used almond milk instead of regular milk and added 1/2 cup of applesauce in place of the egg.
I made them today and oh my goodness, they are divine. They are so moist and not too sweet. I think it's safe to say these will not last long in our house.
