Crush the Little Debbie Christmas Tree Cakes into fine crumbs.
In a mixing bowl, combine the cake crumbs and softened cream cheese.
Stir in vanilla extract until evenly mixed.
Shape the mixture into small balls and place on a baking sheet.
Chill the truffles in the refrigerator for about 30 minutes to set.
Melt the white chocolate chips in a microwave-safe bowl or double boiler.
Dip each truffle into the melted chocolate and coat evenly.
Sprinkle with decorative sprinkles immediately after dipping.
Let the truffles cool completely on the baking sheet before serving.
