To me, I think this is the best way to serve any dip at a party, why? You don't have loads of people perched around the dip bowl at a gathering. For Joshua's 1st Birthday I did these Taco Dip cups and although probably a bit more prep work for me, they were great.
I used the short plastic cups (mine had snowflakes on them to match his party theme), and filled them up.
They are also really kid friendly, because we all know little hands tend to double dip, which is fine when using your own bowl!
