Remove cake layers from the freezer and unwrap.
Place bottom cake layer flat side down on a 6″ cake board. Frost cake top-down. Once frosted, gently flip layer over, round side down, making bottom of cake. Frost bare top of cake.
Gently place other cake layer on top of frosted bottom layer. Frost top half of cake.
Place in refrigerator to set buttercream for about 20 minutes.
Once set, poke wings gently into the sides (not going all the way in) to mark their place. Outline all the snitch designs gently with a toothpick, wiping away any excess frosting that scrapes off.
Place extra frosting into a piping bag with a Wilton #3 round tip attached (or any tip good for writing), and trace outlines.
Insert wings into sides, pushing them in until the lollipop sticks are no longer seen.
Sprinkle cake with gold pearl dust or spray with gold color mist (optional).
Store in refrigerator until about 1 hour before serving.
