Daylight Katie ran away with the mares' bumper in Gowran Park to open up Cheltenham and Aintree options.
David Dunsdon sent the 5/2 favourite clear over a furlong from home and she stormed in by eight lengths.
Joseph O'Brien's Etincelle Lioterie could make no impression on the winner but did come in second at 4/1.
She was four and three quarter lengths in front of 10/1 shot Lunch In Adare trained by Peter Fahey.
Lunch In Adare's stablemate Simonsfleur, a sister of Simonsig, finished fifth on debut.
Winning trainer Gordon Elliott said: "She's a nice filly — we think she's smart.
“She'll be entered in the Cheltenham bumper and the mares' bumper at Aintree and probably more than likely we'll go to Aintree all being well.”
