The public library
is full of diabetes cookbooks. Some are better than others. I like the Joslin books by Polin and Giedt, but my favorite is now out of print, the UCSD Healthy Diet For Diabetes, by Algert and Grasse.
However, my internist, certified diabetes educator, registered dietician, and endocrinologist have all said that if a person's blood sugars are well controlled, there is no reason why a person with diabetes cannot have a small (< key concept there) piece of "normal" cake. Even with frosting. An example would be a 2 x 2 square from a 9 x 13 pan. A slice of angel food cake is another good choice.
It is a question of choices, and information. Many people with diabetes do not test their blood sugar often enough. The more information, the more choices. If a pre-meal blood sugar is 59, (too low) a person can safely have more carbohydrate than if their pre-meal blood sugar was 259. (Way too high.)
It's about balance.
I sincerely hope your Grandmother has a lovely birthday.
