After a brief hiatus due to an injury in October 2022, Stratton made her return on January 10, 2023 at NXT New Year's Evil. In her first match back, she picked up a victory over Indi Hartwell on the January 24 episode of NXT.

In May, Stratton took part in an eight-woman single-elimination tournament, in which she defeated Gigi Dolin in the quarterfinals, Roxanne Perez in the semi-finals, and Lyra Valkyria in the finals at NXT Battleground to win the NXT Women's Championship, marking her first title in her career. On June 27, during the second week of Gold Rush, Stratton successfully defended her title in her first title defense against Chase University's Thea Hail. During the match, Hail submitted Stratton, however, the referee was distracted by Drew Gulak before Stratton ultimately won the match.
