Line a baking sheet with parchment paper.
In a large bowl, place the entire prepared pumpkin pie, including the crust. Using a fork or potato masher, break down the pie until it's completely crumbled. Stir well to combine.
Using a 1-tablespoon cookie scoop, drop balls of the pie mixture onto the lined baking sheet.
Place truffles in the freezer for 25-30 minutes, or until firm.
Roll each portion into a smooth ball. Place back into the freezer for an additional 30 minutes, or until firm.
Line another baking sheet with parchment paper.
When ready, add almond bark to a medium microwave-safe bowl. Heat for 60 seconds. Stop and stir. Then, heat in 15-second increments, stirring after each interval, until the almond bark is melted and creamy. Let it sit for 1 to 1 ½ minutes to cool slightly before dipping.
Remove the truffles from the freezer. Working one at a time, gently drop each truffle into the melted almond bark, making sure they are completely covered.
Using a fork, lift out the truffle. Use a toothpick or another fork to slide the truffle onto the parchment-lined baking sheet. (You may need to reheat the almond bark to keep it a thin mixture.)
Repeat for the remaining truffles.
Place in the refrigerator for about 30 minutes, or until the almond bark has set.
Store the truffles in the refrigerator in an airtight container for up to 2 weeks.
