The 2023 Andy's Frozen Custard 300 was the 28th stock car race of the 2023 NASCAR Xfinity Series, the second race of the Round of 12, and the 19th iteration of the event. The race was held on Saturday, September 23, 2023, in Fort Worth, Texas at Texas Motor Speedway, a 1.5 miles (2.4 km) permanent quad-oval shaped racetrack. The race took the scheduled 200 laps to complete. In a wild and wreck-filled race, John Hunter Nemechek, driving for Joe Gibbs Racing, would steal the win after making a pass on Parker Kligerman and Justin Allgaier with under ten laps to go, and held on to earn his 10th career NASCAR Xfinity Series win, and his seventh of the season. He would also advance into the next round of the playoffs.^[1] Allgaier would go on to have a blistering performance, winning both stages and leading a race-high 133 laps, but a late-race pass would put him in a 5th place finish. To fill out the podium, Kligerman, driving for Big Machine Racing, and Sammy Smith, driving for Joe Gibbs Racing, would finish 2nd and 3rd, respectively.
