And not like "sugar free pudding" either. As good as it is, I've been searching for some relatively low-calorie desserts like cookies or muffins or SOMETHING baking-related to make. Any recipes/suggestions?

and pick up or check your library for Cooking Light Magazine, holiday baking issues are in full force right now and there are a lot of good recipes.

On the fun blog pbfingers.com, Julie has some yummy light desserts - pumpkin spike cookies made with just a few ingredients, etc. Good reading and good pictures on there ... Good luck!
