The stars represent your progress towards the Grand Prize that is displayed at the end of the table. In doing so, you will not only get one of the possible rewards that it comes with, but also one, two or three stars. Once you're done collecting all the necessary ingredients (you can see them in the upper part of the event window) you can bake the recipe of your choice.

What's more, they will be also available in every Daily Challenges chest (except for the very last day of the event)! In case you need the ingredients quickly, you can also get them for Diamonds.

That is not the only way, however! For the duration of the event you will be also able to find them in some of the incidents that you can collect in and around your city. You will probably have a few of them stacked when you get to them, as they start stacking up starting on day one. Once you've completed all of them, you will be getting one quest per day, for the remainder of the event. You will get 54 quests that you can complete right away (as two parallel questlines - the second one will show up after completing the first four quests).

The most reliable way to get them is completing the Fall quests.

There are five ingredients that you can use for baking: Apples, Pumpkins, Chocolate, Cinnamon and Caramel.
