As Ichika Usami makes her way home to prepare a cake for her mother, a strange cream-filled explosion occurs nearby, causing Ichika, along with some other girls, to see visions of sweets. While struggling to cook successfully, Ichika suddenly comes across a fairy named Pekorin, who tells her about the Kirakiral that resides in sweets and helps her bake a successful cake. However, Ichika becomes saddened when she learns her mother can't make it home, losing the motivation to finish her cake. Just then, an evil fairy named Gummy appears and starts stealing the Kirakiral from inside the cakes to make himself stronger, leaving the cakes black as a result. Determined to protect the successful cake that Ichika put her feelings into, Pekorin strives to protect it from Gummy, helping Ichika to realise that her cake isn't pointless. As Ichika is encouraged to finish decorating it on the spot, the cake transforms into a Sweets Pact and the Rabbit Shortcake Animal Sweet, giving her the power to transform into the Pretty Cure, Cure Whip. Using her new rabbit-like abilities, Ichika manages to defeat Gummy, returning all the Kirakiral he stole back to where they belong, after which a strange voice is heard from a shop-shaped bag.
