These "building block" cakes are ideal for a baby shower or first birthday -- are covered with fondant and decorated with royal icing. One sheet-cake recipe will make twelve scrumptious blocks. - but really they could be awesome for any events.
Cute and no rolling diapers! - I love the square cake idea, it's much easier and smarter! I'd use different colors and more decorations but I've never seen the diaper cake in square form before, and I absolutely love it!
