Channel 4's outgoing chief creative officer Jay Hunt, who was behind the show's move, said she would be happy if their version of the Bake Off drew in fewer than half the viewers. Its press office said Bake Off is the channel's most watched show in five years, since London's Paralympics Opening Ceremony in 2012.
However, even if the show was considered a success by many who took to social media to rave about it, official viewing figures show the new format has attracted a lot of less viewers than what the original show used to on the BBC.
Great British Bake Off will continue next Tuesday at 8pm on Channel Four - and it is biscuit week.
The show returned to screens on Channel 4 with new hosts, and a new judge, with fans flocking to crown their baking champ.
Channel 4 famously purchased the Bake Off contract a year ago.
Viewers took to Twitter throughout the episode on Tuesday night, sharing their thoughts on the series.

But if it wasn't for the adverts, Channel 4 wouldn't have been able to bag the Bake Off on their channel in the first place.
Unlike the BBC, Channel 4 is funded via commercials, and has signed Bake Off sponsorship deals worth $5.2 million, while also extending the show to 75 to fit in more than 15 minutes of breaks.
The average peak-time price for a 30-second slot on Channel 4 is around £100,000; however, the broadcaster is charging between £150,000 and £200,000 to advertise within the 8-9.15pm Bake Off window.
