Biscuit dispenser

The Thirteenth Doctor's TARDIS had a custard cream dispenser built into the control console. The dispenser was operated by pressing down a pedal by the floor. (TV: The Ghost Monument)

Behind the scenes
While working on the design of the new control room, Series 11 production designer Arwel Wyn Jones had asked Jodie Whittaker what her favourite kind of biscuit was. After she told him it was custard cream, he added the dispenser to the console. Upon showing her around the new control room for the first time, he directed her to step on the pedal and it dispensed a biscuit much to her joy.
