Prepare Setup: Gather your tools including a large mixing bowl, a handheld mixer, a baking sheet lined with parchment paper, and a microwave-safe bowl for melting chocolate.
Crumb Cakes: Unwrap the Little Debbie Christmas Tree Cakes and carefully crumble them into fine crumbs in the mixing bowl until you have a uniform texture.
Mix: Combine the crumbled cake with the melted white chocolate in the bowl. Use the handheld mixer for smooth integration until the mixture is well-blended and holds together.
Shape Truffles: Scoop out portions of the mixture and roll them into small balls, about 1 inch in diameter, ensuring they are nicely rounded for an appealing shape.
Coat Truffles: Dip each ball into the melted chocolate, coating it thoroughly but allowing excess chocolate to drip off before placing them back on the baking sheet.
Decorate: Roll each coated truffle in your choice of colorful sprinkles, coating them evenly, and then place them on the parchment-lined baking sheet.
Chill: Refrigerate the truffles for about 30 minutes, or until firm. This chilling time helps set the chocolate coating nicely.
Notes
These truffles can be made ahead of time, and they store well in the fridge or freezer.
