In anticipation of summer, here is a sand castle cupcake that I thought was really cute. You could do all kinds of things with this. You could even have a contest to see who can come up with the most creative sand castle cupcake (a much cooler and cleaner alternative to actually getting in the sand, right?).
This display uses finely crushed Nilla Wafers for the sand, graham crackers for the drawbridge, black licorice for the chains, and Teddy Grahams for the people.
