The location is featured in multiple episodes. Pinkie Pie bakes cupcakes there in Applebuck Season, and consumes desserts prepared for the royal visit of Princess Celestia under the pretense of being a food-taster in Swarm of the Century. The first floor holds a store-front, which is also used as a party or gathering space in several episodes, as well as a kitchen and a room with a taffy maker (as seen in Call of the Cutie). The upper floor contains Pinkie Pie's bathroom, which is seen in Feeling Pinkie Keen, while the upper-most floor in the building's cupcake-shaped tower contains Pinkie's bedroom. There are café tables outside the shop for customers to enjoy their treats right outside the store, which Pinkie uses in Griffon the Brush Off.In Party of One, Pinkie holds a birthday party for Gummy (her pet alligator) in her room on the top floor. Twilight Sparkle also stops by the store to buy a cake for Pinkie's surprise party, something Pinkie Pie partly overhears through a hole in the floor of her room which seems to bypass the second floor entirely. When Rainbow Dash comes to collect Pinkie for the surprise party, she enters Pinkie's room through the balcony door at the very top of the building. In Lesson Zero, Twilight buys 12 cupcakes for a picnic with her friends, although Mrs. Cake gives her an extra one for free, making it a "baker's dozen".
In Baby Cakes, even more of the building is shown. Pinkie Pie serves a snack to Pound Cake and Pumpkin Cake in a previously unseen room across from the rear staircase that joins to the kitchen, containing a dining table and shelves of candy. There is another bathroom, where she attempts to give the baby twins a bath. Pound Cake and Pumpkin Cake share a nursery on the second floor where Pinkie Pie attempts to change their diapers and settles them down for their naps, although not before Pound Cake drags her from the room and down the stairs through the main floor. There is also another doorway in the second floor hallway but it is unclear what it leads to.
