The Big 12 squad used its size advantage and athleticism to overcome the slow start and held a 22-15 lead with 9:44 left in the first half on a running floater by Williams and Thompson's trey on the next possession.
Burnham's follow-up slam tied it at 30 with 3:42 left, and the visitors added on with Meeks' two free throws.
However, two freebies each by Kalib Boone and Williams -- plus an alley-oop dunk by Cisse on the last shot -- sent the Cowboys on an 8-0 run for a 43-36 halftime lead, which matched their largest.
In the half, OSU shot 50 percent from both the field and long range, and made all seven free throws.
Despite 16 turnovers, the Cougars shot 50 percent on the three-ball and made their 12 free throws.
