Prepare a large cookie sheet with parchment paper and set aside.
In a small mixing bowl cream together the snickerdoodle crumbs, cream cheese and vanilla extract until smooth. Reserve a handful of the crumbs for garnishing.
Using a 1 inch cookie scoop, scoop the cookie dough mixture and roll into 1 - 1-½ inch balls. Use the palms of your hands to smooth and round each ball. Do this until the mixture is completely used.
Place each truffle ball on the sheet of parchment paper and place inside the refrigerator for 1 hour.
About 5-10 minutes before the chilling time is complete, begin to prepare your melting chocolate by first adding 3/4 ‘s of the wafers to a large bowl. Reserve the remaining wafers for creating the chocolate lines.
Next, place that bowl over a stovetop pot containing 3-4 inches of water. Bring water to a boil, creating a double boiler.
Stir the wafers frequently using a rubber spatula as the chocolate melts. Add 1 tablespoon of the crisco and continue to stir until the chocolate is smooth, silky and fully melted. When done, remove from heat.
Using two forks or dipping tools, dip each cookie dough ball into the melted chocolate, covering it completely. Roll the ball, working it into the chocolate to cover it completely.
Place each chocolate covered truffle on parchment paper and repeat the process for all truffles.
Place inside the refrigerator and allow to cool for an additional 20 minutes.
When the truffles have almost finished chilling, repeat the double boiler process for the remaining amount of white chocolate. Melt down the chocolate, adding the remaining crisco and mix until silky smooth. When done, remove from heat.
Using a piping bag or small plastic Ziploc bag, pipe small white chocolate lines after the truffles moving from side to side.
Immediately top with the remaining snickerdoodle crumbs, sprinkles a couple of pinches over top of the on white lines.
Repeat this process for all truffles one at a time before placing in the refrigerator to chill for an additional 20 minutes before serving.
