Using a 1 to 2-inch cookie scoop, portion out the mixture and roll each into smooth balls measuring approximately 1 to 1.5 inches in diameter using your palms. Continue until all the mixture is used.

Drizzle a small amount of melted chocolate over the top of each truffle using a spoon to mimic chocolate syrup. Place a stemmed maraschino cherry in the melted chocolate atop each truffle and hold briefly until set. Immediately sprinkle with rainbow sprinkles. Repeat for each truffle, working one at a time.
