Brook came into bat four balls into the final day's play of a rain-marred Second Division County Championship match against Leicestershire at Headingley, with Yorkshire 73-3 in reply to the Foxes' first-innings 354.
And the dynamic shotmaker, one of the rising stars of the English game, then provided brilliant entertainment for a hardy crowd of under 200 spectators by smashing 14 fours and two sixes in 69 balls.
Brook, set to be included in defending champions England's squad for the upcoming T20 World Cup in the Caribbean and the United States, was 100 not out when Yorkshire declared on 264-6 shortly before tea.
But the rain which had repeatedly interrupted the game finally ensured the match ended in a draw, with Leicestershire 26-0 in their second innings.
The 25-year-old Brook withdrew from the Indian Premier League following the death of his grandmother.
He had previously pulled out of England's Test tour in India in January, citing personal reasons. Brook explained later it was because his grandmother "was ill and didn't have long left".
