So like anything in the wedding world, you can't just have wedding CAKE any more, you have to have - s'mores, or lollipops, or pudding parfaits, or literally anything BUT cake, because of course you have to be super-duper unique. There's nothing wrong with this (but guys, it's TOTALLY OKAY if all you want to have is cake. I love cake! and NO, wedding cake isn't dry or gross - I promise!)
That said, a great compromise between wedding cake and something more unique is the great American breakfast snack, donuts. Having a donut bar at your wedding can be a great touch that does not have to be labor intensive and can be quite reasonable. I personally believe heaven is a collection of 800 varieties of coffee and an all you can eat (where you never get full!) buffet of donuts. God, do I love them. And while they have been taken over by 'artisans' like everything else these days, not even hipsters can ruin them.
One client LOVES donettes, and had a candy bar with a donette display as the centerpiece, which was simple yet charming. Another client had super-cool and tricked out donuts from California Donuts that their dessert vendor, Fantasy Frostings, picked up and assembled among the rest of their fabulous desserts. Mixing in donuts with another dessert element (such as the ice cream sundae bar below), or keeping it simple with a donut bar, will delight your guests regardless of what brand or style of donut you use.
There are the more unique donuts these days that don't even taste like donuts; I'm going to be honest, they kind of taste like bread and come in vegan and gluten free options, and can be pricey. If you use a new-fangled vendor for these more specialized offerings, be sure to taste them first. Offering a variety will be sure your guests will be fondly remembering your donut bar for years to come.
