Heat treat the cake mix before you start, just so it's safe to eat uncooked. Place it in a microwave safe bowl and heat in 30 second increments, stirring in between. Continue until cake mix reaches 165 degrees, then set aside.
In the large bowl of a stand mixer (fitted with the paddle attachment), mix the room temperature cream cheese until soft and creamy.
8 ounces Cream cheese
Slowly add the cake mix a little at a time, mixing after each addition, until it’s completely incorporated.
1 box White cake mix
Cover the bowl and place in the refrigerator for at least an hour.
Line a cookie sheet with parchment paper and place sprinkles or sanding sugar in a shallow dish or bowl.
Sanding sugar
Using a tablespoon or a small cookie scoop, scoop the truffle mixture in 1 tablespoon scoops and roll mixture into balls with the palms of your hands.
Roll cake balls in red and green sprinkles and place on the lined baking sheet.
Repeat until all of the cake batter and cream cheese mixture has been rolled into balls and covered with sprinkles.
Place back in the fridge for at least an hour or until ready to serve.
Notes
These truffles can stay out for a couple of hours. However, the cream cheese will begin to soften after awhile and they'll need to be placed back in the fridge.
Store in an airtight container in a single layer, placing a sheet of parchment paper between each layer.
