Sugarcube Corner is a bakery and confectionery located in the lands of Ooo and Aaa. Pinkie Pie works and also lives there.
Pinkie Pie bakes cupcakes there, the first floor holds a store-front, which is also used as a party or gathering space, as well as a kitchen and a room with a taffy maker. The upper floor contains Pinkie Pie's bathroom, 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, there is another bathroom, there is also another doorway in the second floor hallway but it is unclear what it leads to.
