Just about anything with chocolate, eggs of some sort, or Peeps. There are a few good Hubs on here with Easter dessert recipes. Another place to check out would be Pinterest or even Google images to check out some interesting and unique ones.
You'll be suprised at the possibilities haha. The one that I really like is the bird's nest made of chocolate covered pretzels with Mini Eggs on top and a Peep chick next to the eggs. They look very cute and taste great as well.
