In this moment we cannot exist the real Butter official font, but instead of fake font as LOBSTER, the great real font alternative for Butter is Sant'Elia Script.

Sorry if I'm a hindrance,but I found another similar Butter logo font which comes very close to the original: it's Aloe Vera (or Aloe).

I think it's Pattaya....

That's very similar to "Butter" logo original! Thanks!
Ah, look this: it's very very similar to "Butter" logo original this "Bulletto Alto" font.
