Another favorite muffin of ours is the "Oatmeal Apple Muffins" from page 40 of Company's Coming Mostly Muffins. I think they are popular because they have a topping of brown sugar, rolled oats and cinnamon. They remind me of apple cake. What's not to love?
I'm sure these muffins would be great with nuts too, but I try to make nut-free muffins so my children can bring them to school.
