Sift the icing sugar. Knead well with marzipan and rose water. (It is best to wear disposable gloves).
Form approx. 12 egg-shaped, smooth balls (approx. 35 g each) from the marzipan mixture. Use scissors to cut small rabbit ears into the balls. Use a wooden skewer to model eyes, noses and mouths. Let the bunnies dry for about 1 hour.
