Gone are the days of chocolate-glazed doughnuts. Boutique doughnut shops have been popping up all over the world, serving up unique flavors and fillings, like LA-based Cafe Dulce, which stuffs their doughnuts with Snickers bars. Australia's Donut Papi offers treats filled with custard, and NYC-based Du's Donuts come in flavors like banana malt, pear clove, and espresso cardamom.

The National Restaurant Association named doughnuts with non-traditional fillings one of the 10 trends that are heating up for 2018.

Originally from Thailand, this unique style of ice cream has become popular around the world, thanks to the intriguing method behind its preparation. Liquid ice cream is poured onto a cold slate, which causes it to freeze; meanwhile it's chopped and rolled by hand and then served in a cup with various toppings.

The National Restaurant Association named rolled ice cream one of the top 15 trends for 2018.

Milk Bar Owner Christina Tosi was one of the first bakers to open the food world's eyes to the "naked cake" — a tiered cake whose unfrosted sides show its layers and give it its name. Her naked birthday cakes are a favorite among Milk Bar devotees, and the less-is-more cake trend has spread to weddings and at-home baking.

Tosi predicts that the trend will continue to spread in 2018.

Tosi cited soft serve as another dessert trend that will continue to grow in the coming year. Plenty of funky flavors started to make their way into the viral food sphere this year. There was watermelon and corn soft serve at Dominique Ansel Bakery in Tokyo, and flavors like green tea matcha, black sesame, and purple ube at Soft Swerve in NYC.
