One of my best friends in elementary school would always bring these in her lunch or on snack days. I LOVED them! One year our school made a cookbook for a fundraiser. My mom bought a copy for herself and stored two away, one for me and one for my sister.  My friend's mom submitted her recipe for the tandy cakes and I love to make them using her recipe. They taste just as good years later.
