In the grocery store I have bought Sweet N Low cake mixes and they are good. I found them with the diabetic foods. I made one for my son's birthday and the kids did not even know the difference.
Good luck
You could read the packages and maybe try dark chocolate. Hubby loves the Dove brand and when I get a craving I have 2 or 3 and let them slowly melt. Unfortunately nothing makes me dump, so I limit myself to the occasional indulgence.
Hugs,
