To make a doughnut in the game Grow a Garden (Roblox), you need to use specific ingredient combinations and cooking steps in the game's cooking event. Here are some basic and alternative recipes to make a donut:

• Basic donut: 1 corn + 1 blueberry + 1 strawberry
• Alternative basic: 1 strawberry + 1 tomato + 1 apple
• Simple version: 1 corn + 1 watermelon
• Rare donut: 1 corn + 1 blueberry + 1 apple
• Mythical donut: 2 sugar apples + 1 corn
• Divine donut: 1 bone blossom + 1 sugar apple + 1 banana (or other variations)
• Prismatic donut: 3 bone blossoms + 1 sugar apple + 1 banana

Steps:

1. Gather the ingredients according to the recipe.
2. Put the ingredients in the cooking pot.
3. Start cooking; it takes about 5 minutes or more depending on the ingredients.
4. Collect the donut by pressing "E" when cooking is done.
5. If Chris P. Bacon is craving donuts, give it to him for bonus rewards.

These recipes yield donuts of varying rarities and rewards in the game. The bigger or higher-quality ingredients you use, the better the donut and rewards you can get.

This should allow creating doughnuts within Grow a Garden during the cooking event.
