Maisie, who plays Tiffany Butcher in the BBC soap, took to the floor with Strictly professional Kevin Clifton on Friday night and wowed the judges with her moves.
The actress was joined by a group of her co-stars for the EastEnders' special and ended up taking home the CiN Glitterball Trophy.
After head judge Shirley Ballas announced that she and Kevin were the night's winners, Maisie jumped up and down and squealed with delight.
She then gushed: "I've honestly had the best week. It's just been amazing!"
Fans of the show are now calling for Strictly Come Dancing bosses to nab Maisie for next year's series of the BBC One dancing show.
Taking to Twitter, one pleaded: "Is it just me that's hoping & praying that @maisie_smithwill be on next year's @bbcstrictly."She was amazing tonight! #ChildrenInNeed2019."
Well if @bbcstrictly don’t sign Maisie Smith up for next year's series they’re seriously missing a trick.
Tweeting Maisie and Kevin directly, another said: "Would love to see you both coupled up on next year's strictly as you were both incredible. I think Maisie would be amazing at ballroom and latin."
A third even wrote: "Well if @bbcstrictly don’t sign Maisie Smith up for next year's series they’re seriously missing a trick. She was brilliant!!!!"
Children in Need features a Strictly special each year. Last year, boyband Boyzone took to the ballroom, with Shane Lynch winning.
The Strictly 2019 CiN special featured an Albert Square-inspired set and the cast danced to the Motown classic, Dancing In The Street.
Joining Maisie on the floor were her co-stars Louisa Lytton (Ruby Allen), Rudolph Walker (Patrick Trueman) and Ricky Champ (Stuart Highway).
Strictly judge Craig Revel Horwood even got in on the action by taking on the role of landlord in the Queen Vic in the opener!
Meanwhile, this year's remaining Strictly contestants will be dancing at the famous Blackpool ballrooms when the series continues on BBC One, tonight at 7.05pm.
