Observations with the Plateau de Bure Interferometer in the most extended configuration toward two intermediate-mass star-forming regions, IRAS 22198 6336 and AFGL 5142, reveal the presence of several complex organic molecules at ~500 AU scales, confirming the presence of hot cores in both regions. The hot cores are not rich in CN-bearing molecules, as often seen in massive hot cores, and are mainly traced by CH3CH2OH, (CH2OH)2, CH3COCH3, and CH3OH, with, additionally, CH3CHO, CH3OD, and HCOOD for IRAS 22198 6336, and C6H and O13CS for AFGL 5142. The emission of complex molecules is resolved down to sizes of ~300 and ~600 AU, for IRAS 22198 6336 and AFGL 5142, respectively, and most likely is tracing protostellar disks rather than flattened envelopes or toroids as
