Tap the Cake Button on the Map during the event to enter the Event Bakery. Selecting the green Play button starts a 5-Layer Cake Level. You need Event Lives, Oven Mitts, to play Event Levels.

You must complete each level without losing to win the Event. If you fail a level, you will return to level 1 of the event to start over. If you complete all levels in a row without losing, you will receive the 5-Layer Cake Event Reward.
