Mary Berry and Paul Hollywood will be setting the last challenges for the three finalists and firstly they'll have to tackle enriched dough in the signature, creating filled iced buns.
The technical sees them taking on something they have previously struggled with, and the last ever show stopper tasks them to make a classic British cake.
Who will Mel Giedroyc and Sue Perkins be crowning as the winner?
