You can get so carried away with creating the most complicated birthday cake (thanks Pinterest!) however if you take a step back, have a look at some simpler options they can have just the same effect as a really complicated one! Simple can really be the best.
I found these super cute cakes when searching for something else (always happens). I've tried to only choose ones that are realistic and simple can be whipped up in an hour, because let's face it, who has more time than that to whip up not only the wow factor for your birthday party but the highlight of your loved ones birthday?
