If she is not overweight, and her blood sugars are well controlled, she should be able to work small amounts of "sweets" into her diet just fine.

The problem with "diabetic" foods (low sugar cakes, cookies, etc.) is that they are still often high in calories, fat, and carbs, and leave the person feeling unsatisfied. The person may even eat more of these than they normally word, defeating the purpose.

A better way is to have her eat her normal healthy diet, and perhaps add a small treat afterwards. For example, a SMALL dark piece of rich chocolate or a Halloween size mini chocolate bar (15 grams of carbs) is an OK treat.

It sounds like she is just going to binge if you only allow her what she has been eating, which defeats the purpose. As long as she is not eating an entire candy bar on a regular basis, one regular candy/mint after dinner should be fine.

Some people with diabetes like to use Splenda in their baking. I am not a fan of this because it causes people to think that it's OK to make "junk" foods a regular part of their diet as long as they are sugar free. These foods are still empty calories, carbs, and fat, none of which a diabetic needs. Once in awhile is fine. Others do not like to use artificial sweeteners due to the perceived safety concerns, side effects, taste, or the fact that studies show that they may cause people to eat more.

Some studies have linked Splenda to an increase in A1c, a test used to determine the average blood sugar over the past 3 months. Some Type 1 diabetics report an increase in blood sugar after comsuming Splenda.

Stevia is a natural herb that is used as a sweetner. I am not sure how well it will hold out for baking, but it can be used for coffee and cereal. I always reccommend Stevia over Splenda.

That said, Splenda is an option some people decide to use and they are very happy with it.

I would also make sure that she is not experiencing low blood sugar when she is having these cravings. Make sure she tests her blood glucose level when these cravings occur. She may need a change in her treatment plan.
