You could buy Maison du Chocolat's $1,200 "Easter Atelier," or you could make one of these chocolaty Easter treats. 
Cocoa-Carrot Cake with Cocoa Crumble

For Easter candy lovers with refined taste, there is now an chocolate Easter bunny tableau available from New York’s Maison du Chocolat. The “Easter Atelier” depicts four chocolate bunny rabbits (made with milk, white and dark chocolate) preparing pastries in an entirely chocolate kitchen. The edible scene is about a foot wide and ten inches high. Unlike cheapo drug store bunnies, these are filled with ganache, so the whole thing weighs in at eleven pounds. It looks fantastic, and it can be yours for $1,200. If that's more than you were planning to spend on your basket, you could make one of these much more affordable chocolaty Easter treats.
