Glutenfree apple cinnamon muffins

It is not always easy to bake cakes without gluten, the result vary to say the least. So I think muffins is the best way to go, they never fail me. This is a fall version with apples, sugar and cinnamon.  The muffin recipe is a great basic one to use for other flavours as well, like chocolate, berries or why not citrus.
