Add the caramel melts to a medium mixing bowl that is microwave-safe. Place the green melts in a separate microwave-safe bowl. Pour one can of the sweetened condensed milk into the bowl of caramel melts.
Add the green apple candy flavoring to the second can of sweetened condensed milk. Stir well to mix the flavoring into the milk, then pour into the bowl of green candy melts.
One at a time, microwave each bowl in 20-second intervals, stirring between, until melted and smooth (about 2 minutes).
Pour the caramel mixture and the apple mixture into the prepared pan, a little at a time, alternating between flavors, so you have a swirl pattern. Place the pan in the fridge to chill until completely set.
