Gingerbread with Caramel Cinnamon Sauce (Gluten Free, Vegan)

Cold weather just screams for homemade gingerbread.  I love this cake's homey simplicity.  I love gingerbread  better than any other cake except for maybe apple.  It's perfectly fine plain, but adding the Caramel Cinnamon Sauce gives it a touch of elegance I think it deserves.
