I feel like I should be appologizing to all the dieters today, but this is the only recipe I have that I know came from my grandmother. She would have been cooking during the Depression, so the using of left overs sounds right. Of course, you can adjust the amount of butter & sugar you used - I suspect Grandma used a very light hand (see Depression cooking, above).
My mother would make this for us if we had hard rolls that went stale & for us, it was a treat. Another fond childhood memory.
