Valastro, real name Bartolo Valastro Jr., was arrested and charged with drunk driving last month after police pulled over the famed baker's yellow Corvette and smelled alcohol on him.
The complaint said Valastro's blood-alcohol content measured 0.09%, which is above the state's legal limit of 0.08%.
In New York, DWAI is a violation, not a crime, and Valastro's license will be suspended for three months, AP said. It's defined as driving with a BAC between 0.05% and 0.07%.
The reality star was sentenced to a conditional discharge and ordered to pay a $300 fine, the Manhattan District Attorney's Office told E! News. He must also complete a drunk-driving program.
After entering the plea, the 37-year-old New Jersey resident took to Twitter to apologize and make his case.
Then Valastro vowed to "never get behind the wheel of a car again, even after one sip. My sincerest apologies to my family, friends and fans."
