Should I simple syrup a carrot cake?

Noooooo. I would stay away from the simple syrup in this case. Makes my teeth hurt to even think about it.

Most carrot cakes are quite moist (most recipes have at least 1 cup of oil). If your carrot cake came out dry, then maybe brushing with a little simple syrup can help. Or you can frost with cream cheese frosting. I hesitate to soak with simple syrup because it can make a cake gummy if its texture is fairly soft.

It seems like carrot cake should be moist and sweet enough without it. I'd be afraid it might end up achingly sweet.
