Line a baking sheet with parchment or wax paper and set aside.
Crumble the Christmas Tree Cakes and add them to a large mixing bowl.
Cut the cream cheese into large chunks and add to the bowl.
Use a hand mixer to combine the cream cheese and Christmas Tree Cakes.
Use a 1 1/2 inch cookie scoop to roll the Christmas Tree Cake mixture into balls.
Place the balls onto the parchment lined baking sheet.
Once all of the batter is rolled, move these to the freezer to chill for 1 hour.
After that, add the white chocolate chips to a microwave safe bowl and microwave for 20 second increments, stirring well in between, until melted.
Drop the melted chocolate over the truffles, letting the excess drip back into the bowl.
Place the covered truffles back onto the parchment and quickly sprinkle with sanding sugar.
Repeat for all of the truffles.
Once all of the truffles are coated and sprinkled, use the cookie icing to draw red lines onto the truffles, resembling the Christmas Tree Cakes.
Move the truffles to the refrigerator to chill for one more hour.
Break off any collected extra chocolate or icing from the bottom of the truffles & enjoy.
