"Cake Boss" Buddy Valastro is recovering following a horrific bowling accident where his right hand was impaled ... and required multiple surgeries.
The famous baker suffered the gruesome injury Sunday while spending some QT with his family in the bowling alley in their home. A rep tells us there was a malfunction with the bowling pinsetter -- a problem the family's had in the past and usually a common fix, but not this time around.
We're told Buddy tried to release a bowling pin from the cage mechanism, but his right hand got lodged and compressed inside the unit.
