Popular children's birthday cake designs include character-themed cakes or cakes with cars, princesses or animals. Local bakeries usually provide online or in-store catalogs of selections, while sites such as Parenting.com and BettyCrocker.com provide recipes for featured cake ideas.
Sometimes children's birthday cakes match the theme of the party, for example castle cakes for little girls' princess parties or train or pirate cakes for a boy's party. Character-themed cakes are popular when they feature easily recognizable characters from children's movies or favorite television shows.
Most children's cakes use bright colors and appealing ingredients like generous amounts of icing and detailing with hard candy or contrasting sprinkles. Another popular option is to make a rainbow layer cake or cook something with different parts of chocolate and vanilla so that picky eaters have a choice of flavor.
