Hot Cheesy Sweet Onion Dip

One of our favorite things to do as a family, after a busy week, is to sit down and watch a good movie while munching on chips and dip.  I also love making new dips for us once in a while.  This is a new addition to our family and it quickly became a favorite.  It's sweet, oniony, creamy, cheesy, etc, etc.  It's so, so, so good that you'll have a hard time stopping to eat once you start!  YUM!  Enjoy!
-3 (8 oz each) packages cream cheese, at room temperature
-1 large sweet onion, cut into chunks
-2 cups Parmesan cheese, grated
-1/2 cup mayonnaise
-1 tsp cayenne
-3 Tbs chopped chives, divided
-1 tsp salt
-1 tsp pepper
Preheat the oven to 425 F.
In your food processor, add the cream cheese and onion.  Process until smooth.  Add the Parmesan, mayo, cayenne, 2 Tbs of the chives, salt and pepper.  Process until well combined and smooth.
Transfer mixture into an 8x8 baking dish. Bake in preheated oven for 25 minutes or until puffed and golden brown.
Remove from the oven and let it sit for 10 minutes.  Sprinkle with remaining chives and enjoy warm!
