The episode begins with the animated characters JJ, TomTom, and YoYo sitting at a table, playing with Play-Doh. JJ is wearing a blue shirt and glasses, TomTom has on a red shirt, and YoYo is in a yellow shirt. They start singing "Pat-a-Cake, Pat-a-Cake, Baker's Man" in ASL while showing the signs for each word. The characters start demonstrating the motions of patting the dough, marking it with a B, putting it in the oven, taking it out, and sprinkling sugar on top. The signs for the words "roll it," "mark it," "bake it," and "pull it" are also included in the song.

As the episode continues, the characters show children how to make their own "pretend" cake out of Play-Doh. The characters demonstrate different shapes and decorations, such as stars and hearts, using different colors of Play-Doh. They show children how to roll the Play-Doh into balls and pat them into shapes, just like in the nursery rhyme. The characters encourage children to get creative and decorate their "cakes" however they like. They're based in convenient locations including supermarkets, newsagents and train stations. Plus they're often open late and on Sundays. Throughout the episode, the characters introduce ASL vocabulary related to the topic, including the signs for "dough," "oven," "sugar," and "bake." These signs are explained and demonstrated several times throughout the episode to reinforce learning. Children are encouraged to practice signing along with the characters and try making Play-Doh shapes at home. Items that are not available in store will take 3-5 working days (excluding weekends and bank holidays) to be delivered to your nominated store. Throughout the episode, the characters also demonstrate important values such as sharing and taking turns. They model positive behavior towards each other, such as helping one another with the Play-Doh and sharing tools fairly.The episode ends with the characters singing the song one last time, encouraging children to continue practicing their ASL and Play-Doh skills. They remind children that learning can be fun and that they should continue to explore and create. As the characters continue singing and signing, they are joined by other characters, including mom and dad. They all sing together, showing the signs and motions for each word. The characters use facial expressions and body language to help convey the meaning of the song to the children. The song encourages children to join along and pat their own "cake" while singing the lyrics.
