Don't suggest the "Snickers" Font. That's the old design. I'm looking for the current one. As shown in the pic.

I suspect that this will be custom since Mars can afford such for branding. I'm old enough to remember when this chocolate bar was called Marathon, and was bigger. If you wanted to emulate it, a starting point might be this (Not the 'font').

Call me crazy, but this is the font

I think OP may already have considered and ruled out Snickers. "Don't suggest the "Snickers" Font." (Take a close look at the 'K')

Well... In that case... You're crazy. Because that's the old font, that hasn't been used for years.
