Gather all ingredients and tools, including mixing bowls and a baking sheet lined with parchment paper.

In a large bowl, mix the vanilla cake mix and softened cream cheese until smooth and fluffy.

Cover the bowl with plastic wrap and chill in the refrigerator for 30 minutes to firm up the dough.

Scoop out one-inch portions of dough and roll them into balls, placing them on the prepared baking sheet.

Melt white chocolate chips in a microwave-safe bowl at 20-second intervals until smooth.

Dip each truffle ball into melted white chocolate using a fork or toothpick, allowing excess chocolate to drip off before rolling in the cinnamon sugar mixture followed by powdered sugar.
