The 33 year-old defended his WBO super bantamweight belt for the first time since regaining the strap with a unanimous win over Cesar Juarez last December by stopping Zsolt Bedak in just three rounds.
Donaire was by far the more superior of the two and wasted no time finishing the out-of-depth Hungarian in Cebu City to make it an impressive 37 wins from his 40 bouts.
In the co-feature, Mark Magsayo remained undefeated with an impressive six-round win over Chris Avalos at featherweight.
Magsayo, 20, made it 11 early finishes from 14 victories but had to pick himself up off the canvas in order to do so. Magsayo was down in the third round, although rallied to drop Avalos in the fifth, before piling on the pressure to force the stoppage in the next session.
Also on the bill at the Sports Complex, Paul Fleming was also forced to take a count before seeing out a unanimous decision win over Miguel Gonzalez.
The 22 year-old super featherweight is now 22-0 and on the move in the WBC rankings after claiming the vacant Continental Americas belt.
Rocky Fuentes and Jason Pagara both scored points triumphs earlier on the Cebu card.
