I’m looking for a specific fic. I’m not sure if it’s Tony/Bucky or what, but the plot is that Bucky likes to make cookies on movie nights and refuses to share them with anyone else. The other Avengers (minus Tony) plot to steal the cookies. One night Tony comes up for movie night and is completely exhausted from a workshop binge. Winter Soldier picks Tony up and starts hand feeding Tony cookies while everyone else watches.
