Lois,
You are amazing - such a simple idea that is wonderful! I know what I'm making for my mother-in-law and grandmother-in-law this week.
My MIL had an accident on wednesday and was in the hospital overnight. She is home now and very sore but OK. She was at therapy on the treadmill and hit a wrong button and her feet went out from under her. She was hanging to the handlebars when this happened and pulled both arms out of their sockets - OUCH! They were able to restore the joints without surgery - Thank God. She has limited movement in her arms currently but this is susposed to fade and she will have normal arm usage fairly soon.
She loves cupcakes and these will be a big hit.
Thanks for posting!
