Heat the heavy cream in a saucepan for a few minutes. Don't allow it to boil, simply get it hot. Turn off heat.
Add the chocolate and allow it to sit for about 1 minute. Add all of the spices and begin stirring until completely melted and smooth.
Place in refrigerator for 3 hours to chill until set.
When chilled, use a mini ice cream scoop or melon baller and scoop out the chocolate and roll between your hands to form balls. Place on parchment paper until you finish making all the balls.
In the microwave, melt the chocolate chips and shortening. Stir until smooth.
Place a toothpick into a ball and dip into chocolate allowing the excess to drip off.
Place on parchment paper to dry while continuing with remaining truffles.
Sprinkled crushed ginger snaps over the top before completely dry.
