Try this instead:
Half the sugar with added cinnamon, nutmeg, or vanilla
In traditional baked goods, the final product will not be affected if you reduce the total amount of sugar. Try using only half of the sugar that the recipes calls for, and add spices such as cinnamon or nutmeg to intensify the flavor. Flavor extracts such as vanilla, peppermint, or almond add additional flavor without the added calories.
