The cookbook 'Sweet and Sugarfree' by Karen E. Barkie is full of all natural, fruit sweetened desserts. It has cakes, cookies, crackers, pretzels, puddings, etc. Several recipes use applesauce or juice, and several use bananas. I am not a diabetic but I would think the recipes would qualify, or be easily adapted.

Here is one recipe from the book
