Charlie/Don in an appartment with cake

[vixenonthemoor.livejournal.com]

I'm looking for an old Charlie/Don fic where they end up in an apartment together (and they could be painting, maybe?) and a neighbour brings them cake or casserole or something? I know it's a lot longer than that, but that's all I can remember - I haven't read it in years, and haven't seen it for just as long.

I'd appreciate any help you could give me.
