If you are using individually wrapped caramels, be sure they are fresh! If they are stale or old the caramel will be extremely tough after it is melted.
I prefer how almond bark melts and spreads compared to white chocolate. It is also hard for me to find white chocolate where I live but either will work, It’s your preference.
Once the caramel and other toppings are melted, I keep them warm by placing the containers in a large baking dish filled with a couple inches of hot tap water. Keeping them in a warm water bath makes it easier to keep everything melted if decorating is taking a while.
These caramel apple slices will last for a few hours for a party or a treat delivery, but keeping them overnight isn’t recommended. Since the apples are cut, the moisture from the inside of the fruit will evaporate and cause the caramel to slide.
