Would help to know the menu as well....
I am assuming your specialty is barbeque (screen name) and down south banana pudding and fruit cobblers are traditional desserts served with this type meal.
Unless there is some way the pudding can be kept at optimal temp ( for flavor as well as safety) I would move on to a cobbler.
Pecan pie is also a go to but the price of nuts has made it almost impossible to make a profit on it.
Texas sheet cake with a hint of cinnamon could be an option as well.
Depends on the rest of the menu......
