A:AnswerHot Fudge and Caramel have so much sugar in them that they will tend to burn faster, than your cheddar cheese will, and even the "Warm Setting" won't be cool enough to keep them from burning.
A:AnswerI don't understand why it wouldn't be ok to heat ice cream toppings like hot fudge. We use a slow cooker for nacho cheese, I can't imagine it's that different. I think the manufacturer should explain why they don't recommend heating toppings like hot fudge? Wouldn't it be fine on just the warm setting?
