A Queens man told a judge in chilling detail yesterday how he sneaked up on his wife as she slept and brutally bludgeoned her to death with a baseball bat.

“I hit her in the head while she was sleeping in the bed,” said Jordan Hawes, 32, as he answered questions by prosecutors in order to fulfill a plea agreement in exchange for a 25-year sentence for the murder of Tara Hawes.

“I don’t remember how many times,” he told Queens Supreme Court Justice Dorothy Chin-Brandt of the savage beating.

He was facing 25 years to life for the Jan. 30 murder, as well as grand larceny and other charges, but promptly decided to take a plea to manslaughter.

The move spared both his and his slain wife’s family from suffering through the gory details at trial.

Tara, a teacher, was found dead by family members on Feb 2. Hawes is expected to be sentenced on April 16.
