For a taste of something both wacky and wonderful this Easter, consider serving egg shells filled with cake. Yes, you read that right. By creating a small hole in an eggshell and emptying its contents into a bowl, then, obviously, cleaning the shell very well, you are left with the perfect cupcake container. Pour a little of this lemon and sour cream cake batter into each shell and bake. The best comes when you serve them to guests and watch their eyes light up!
