I think it's even worse than that. I hate this test because both now and as a kid I'd take the single marshmallow and just be done. I don't want two, even if you hand them to me back-to-back... let alone 15 minutes later.
I don't care if its my favorite treat either. I believed quite strongly that a little vs a lot doesn't matter: the best parts are in the anticipation, the initial bite, and enjoying the lingering aftertaste. Having more more bites to eat is a gimmick with nothing but downsides (however now I get how things like addiction can drastically alter that equation so the "more" is practically everything).
So show me a version of this test that doesn't have the assumption "all kids are greedy for food and the most successful ones will optimize for that" at its core.
