Baked Brie with Caramalized Onions and Cranberries

Ok, let's just throw this out there.  I love Cheese.  Love.  There's a kazillion types and I'm pretty sure I like 99% of them.  Oka, Camembert, Gorgonzola, Parmesan, Havarti, Blue, Fresh Mozza, Goat.....seriously, the stuff is bloody brilliant!!
This, you'll not regret making.  I came up with this in about 5 minutes, wrote down all my ingredients and am I ever glad I did.  It was inhaled my myself, the husband, brother-in law and his wife.  Gone in no time flat.  Sub in a Camembert if you want to...equally DELISH!
p.s. you can easily adjust the seasoning and sugar to your liking.  If you don't have brown sugar, use maple syrup!
