Bunny Cake - super easy, it's 2 circle cakes, one cut into the bow, which leaves the curves for the ears. This one is nicely decorated, I usually make mine with coconut topping the cake for "fur", jelly beans for eyes and nose and twizzlers for whiskers. Easy but impressive.
Rainbow activities: St. Patrick’s Day Rainbow Treats. Could make up just a few and hide them in one place, then give clues for children to look for. When they find the St. Paddy's day stash they can share it. (A gift from the leprechaun!?)
