The filly, trained by Alain de Royer-Dupre, won a hard-fought Group One contest ridden by Christophe Soumillon.
"The pace wasn't that quick," Soumillon said. "I wouldn't say I wasn't happy but a quicker pace would have been better as she was a bit keen.
"When I asked her to go at the two-furlong marker she was going very well and I knew I just had Frankie to beat."
"I was quite surprised they haven't been going up the far side as it's virgin ground.
"A quicker pace would have been better as she was a bit keen but she had a good target in front of her and she won like a champion filly."
The Irish Thoroughbred Marketing Cherry Hinton Stakes won by the well-backed favourite, Sendmylovetorose.
The Andrew Oliver-trained filly came home ahead of Maureen by just a neck, with Jadanna and Premier Steps third and fourth respectively.
Winning jockey Colm O'Donoghue said: "She's still relatively inexperienced, I didn't get to teach her much the first two runs, but she's got the ability and handles the ground.
"I'm delighted for connections. She's a lovely filly and has gone from strength to strength. Andy gave me a lot of confidence and said do your own thing.
"She's quite light on her feet and could handle better ground too. She's got the class to do it on that ground and that's the sign of a good filly.
"She's still raw and green so there's more to come."
