There are quite a lot of desserts that do not involve gluten. For instance puddings, some fruit desserts like baked apples. You can make fruit desserts by simply cutting up the fruit, adding a little sugar, as much as you personally like, and cooking it on the stove for a bit, adding spices like cinnamon ect and then serve with a scoop of vanilla ice cream.
I have been experimenting with gluten free healthy "cookies" and "cookie bars" but they hardly qualify as a dessert because I use almost no sugar at all.
Be careful with gluten free desserts though, white rice flour is a common ingredient and it is even higher on the glycemic index than white wheat flour. If you use it, you will want to add extra eggs for protein and/or more butter or oil to balance it.
