These are best when eaten right after they are made. If you would like to store leftovers you can cover the apples with plastic wrap or put them in an airtight container and store in your fridge for 24 hours. I recommend putting a little lemon juice on the apples before your store them to help prevent the apples from turning brown. The next day your apples may have a little more liquid around them from the caramel and toppings but they will still taste delicious!
