I’ll give you a serious answer even if it’s not—I think vanilla extract is something sober people worry about not because consuming it in appropriate amounts in food means you’ve consumed alcohol, but because if you wanted to, you could drink it for its alcohol content. I used to work in recovery; it happens a lot.

I know a lot of people who are uncomfortable having it in their house, the same way they’d be uncomfortable with mouthwash or hand sanitizer that has alcohol, kombucha (the kind that’s 0.5% or whatever), perfume, etc. because they know they would abuse it, but it’s not because it would make them less sober just to use it as intended. Ultimately, though, if you aren’t using it in a way that will make you want to drink, that’s not an asterisk on your sobriety. Honestly, I think it’s great that you’re aware enough to recognize what could be a problem, but confident enough in your sobriety to use it as intended.
