An Australian thing that I love the idea of is fairy bread. It's a thing that is common, I understand, at children's birthday parties. It is, essentially, bread with (vegan) butter and rainbow sprinkles. How is this not part of American cultural practice?
For my friend's 30th birthday, Andy and I contributed fairy bread (along with some hemp seed cinnamon rolls - which reminds me, you should enter that competition). It is a seemingly simple thing to prepare, but there is actually a trick to getting the sprinkles to stick.
Butter bread, put sprinkles on a plate or shallow bowl.
Dip bread, butter side down, into sprinkles.
Slice bread into triangles, removing the crusts if your crowd is picky.Stack artfully onto a plate.
And the real trick - let them sit around (covered, of course) for an hour or two before you eat them. The sprinkles kind of melt into the butter and the whole thing is much greater than the sum of its parts.
This is a birthday tradition I would like to see incorporated into more grown-up parties.
