Preheat oven to 350 degrees.  Carefully slice the rind off the top of the Brie wheel, but do not remove.  Bake the brie for 10-15 minutes.  When the brie is done baking, the top can be easily removed. 

     While the brie is baking, in a medium saucepan, bring Kahlua and brown sugar to a boil and simmer 6-8 minutes.  Add the pecans for the last 2 minutes.       

     Remove the brie from the oven, remove top and pour the Kahlua sauce over the brie. 

     Serve warm with crackers or sourdough bread.
