A quick rum, caramel sauce for a delicious no bananas foster, grandma's favourite!
Mix brown sugar and butter over medium heat in a heavy-bottomed saucepan until sugar is dissolved.
Once sauce begins to thicken slightly about 8-10 minutes, whisk in apple juice and cinnamon. Bring to a boil and remove from heat immediately.
Stir in rum.
Serve over ice cream.
