In Grow a Garden, to make a cake, you need to gather specific ingredients and use the Cooking Pot located in the middle of the island. Here is how you do it step-by-step:

1. Collect the ingredients based on the type of cake you want to make. Cakes have different recipes depending on their rarity. Some example recipes include:
   • Uncommon Cake: 1 Strawberry, 1 Tomato (or 1 Carrot), 1 Corn, 1 Apple
   • Rare Cake: 2 Watermelon, 2 Corn or 1 Corn, 1 Watermelon, 1 Tomato
   • Divine Cake: 1 Corn, 4 Sugar Apples or 1 Banana, 1 Kiwi, 3 Bone Blossoms
   • Prismatic Cake: 3 Bone Blossoms, 1 Sugar Apple, 1 Banana
2. Once you have your ingredients, go to the Cooking Pot in the middle of the island.
3. Equip an ingredient and interact with the pot to add it to the ingredients list on the left of the screen.
4. Add all the required ingredients for the cake recipe you want.
5. When all ingredients are added, press the "Cook" button to start the cooking process.
6. After cooking finishes, interact with the pot again to retrieve your finished cake.
7. Equip the cake and give it to Chris P. Bacon by talking to him and selecting "Try this food I cooked up!"

Larger sizes of plants used in cooking may yield bigger reward cakes. The exact cooking time and pot color requirements may vary, but it takes around 5 to 7 minutes in-game to cook a cake.

If you want to mass farm cakes, plant and grow the required ingredients from the seed shop, then repeatedly cook them using the recipe.
