"Peanut Butter" is a song by funk/r&b band Twennynine, released in 1980 on Elektra Records as the first single from their second album, Twennynine with Lenny White. The song peaked at No. 3 on the US Billboard Hot R&B Singles chart.
Allmusic's Jason Elias, in his review of Twennynine with Lenny White, exclaimed "The cutesy "Kid Stuff" is a little too silly, but honestly, this (new) incarnation of the band certainly could get away with it."
