Arrange the white sprinkles, Christmas-colored sprinkles, and crushed candy canes in three separate rows on a shallow dish or three small plates. Make each layer about ¼ inch deep.
Place the semi-sweet melting chocolate in a microwave-safe bowl. Melt according to the package instructions, stirring until smooth.
Transfer the melted chocolate to a piping bag or a zip-top bag with a small corner snipped off.
Pipe small circles, about ½ inch wide, directly onto the sprinkles and crushed candy canes. Continue until you've used all the chocolate or about half of the sprinkles.
Let the candies sit for about 5 minutes, or until completely firm. You can place them in the refrigerator briefly to speed up the process.
Once hardened, gently lift the candies from the sprinkles using a fork.
Repeat the process with the white chocolate melting wafers, melting them until smooth before piping onto the remaining sprinkles and candy canes.
Let the white chocolate candies harden completely, then remove them from the sprinkles.
Transfer all the finished candies to a festive bowl, mason jar, or holiday gift bags. Enjoy or give as homemade Christmas treats!
