Triple Threat Chocolate Cheesecake

The mothers of boys out there will understand my plight with trying to stay connected to my two sons as they're growing older.  It seems like it gets harder every year to find common ground with them that lends to quality time spent with them as well.  My oldest son Daniel, who is now 22, shares my passion for cheesecake and together we've discovered a common interest in the television show Duck Dynasty.  Daniel was ready to reach beyond our comfort zone of plain cheesecake and into the wonderful world of flavored cheesecakes.  I searched many recipes and decided to try my hand at a chocolate Cheesecake.  I developed a recipe that I thought Daniel would enjoy and made it for his birthday.  Since he also wanted a Triple Threat Duck Call from Duck Commander for his birthday it occurred to me to bring our two shared interests together and name this cheesecake the "Triple Threat Chocolate Cheesecake" due to its three chocolaty layers. I just had the pleasure of teaching his beautiful fiance how to make this dessert for him. In some way I feel like every time she makes it for him, I'll be there with them. Thank you Duck Dynasty for inspiring wonderful time spent with my son, a delicious treat and a new family tradition!  So without further suspense, here is the recipe for the most decadent cheesecake you will ever eat!
