Cupcakes are a currency that you can get by selling your bakery, cupcake storms and special loot bags. Cupcakes give you 0.05% per one and can be upgraded with rainbow cookies (starting at 4,000 and increasing). Each upgrade gives you + 0.05% more boost (increases every 5-10 upgrades). Every time you sell your bakery, cupcakes get increasingly harder to earn, and most players start to hit a wall around the novemvigintillions of cookies, and about 175,000 - 250,000 cupcakes, depending on your early - game strategies. Cupcakes are needed for showcase items unlocked at 50,000 - 200,000 cupcakes.
