The Best thing you can do when feeding Poffins is get a high Level with low smoothness. If you're interested in getting as many Ribbons on the same Pokémon. Try to max out other Pokémon's Contest stats then visiting the Scarf guy in Pastoria City. These Scarfs add to your Pokémon's Contest stats. While consistent the Poffins from the Basement of Veilstone Department Store offers enough to possibly at least one or two stats.
