The Bake Off final typically runs around 75 minutes to 90 minutes, depending on the year and the broadcaster, with a common format being an 8:00 PM to 9:15 PM slot (about 75 minutes) for the final episode in recent seasons. For example, many recent finales have started at 8:00 PM and finished around 9:15 PM, totaling roughly 75 minutes of airtime, though this can vary by series and special editions. If you’re asking about a specific season or year, I can confirm that exact runtime.
