Warm up vanilla candy coating (or white chocolate) in microwave until completely melted and smooth. Mine took 2 min and 15 seconds total.
Dip Oreo cookies into melted white chocolate with a fork.
Place dipped cookie onto wax or parchment paper.
Sprinkle immediately with sprinkles while coating is still wet. Or you can decorate with the glitter gel and/or icing here too.
Let coating harden and set before enjoying!
Store leftover cookies in a freezer bag for up to 3 days at room temperature.
