To cook a cake in Grow a Garden, follow these steps:

1. Gather ingredients from your garden. Cake recipes vary by rarity, with ingredients including fruits like strawberry, tomato, corn, apple, banana, sugar apple, bone blossom, and others depending on the type of cake you want to make.
2. Go to the Cooking Pot located in the middle of the island.
3. Equip one ingredient and interact with the Cooking Pot to add it to the mix. Repeat this until you have added all the ingredients for your chosen cake recipe.
4. When all ingredients are added, press the "Cook" button to start cooking.
5. Wait for the cooking process to complete, then interact with the Cooking Pot again to collect your finished cake.
6. If desired, equip the cake and talk to Chris P. Bacon to give it to him, especially if he is craving that recipe for special rewards.

Example of a simple uncommon cake recipe: 1 Strawberry + 1 Tomato + 1 Corn + 1 Apple. More advanced recipes include rare, legendary, mythical, divine, prismatic cakes, each requiring different combinations and quantities of ingredients such as bananas, bone blossoms, and sugar apples. The bigger and rarer the ingredients used, the longer the cooking time but the better the rewards you can get. This cooking mechanic is part of the in-game Cooking Event by Chris P. Bacon on the Grow a Garden island.
