Dunkaroos, Pop Rocks, Cosmic Brownies: These were more than just snacks to young people growing up in the decade of the 1990s – they were a way of life. Much like fashion, pop culture, and so much more from the era, the nostalgia craze has hit full force when it comes to snacking. PVDonuts in Rhode Island offers a limited-time ‘90s-themed menu full of mouthwatering millennial favorites including the above flavors.

Breakfast sandwiches are another way to go with your donuts. Eleonora Lahud of C&H Sugar says that the company has noticed a rising trend in donut breakfast sandwiches. She suggests the idea of a parmesan donut filled with ham, cheese and a perfectly cooked egg. Duck Donuts found success with its OBX Donut Breakfast Sandwich, featuring a sliced donut customized with a choice of egg, cheese, sausage or bacon, maple drizzle and chopped bacon.

"Spiked donuts" are amazing treats that are just for adults. Donuts can be filled with pastry cream infused with coffee, almond or hazelnut liqueur. Rum, bourbon, tequila or beer can be used as well.

Think cereal donuts (with marshmallow, fruit flavor or cinnamon cereals) or Girl Scout cookie donuts like Thin Mints and Samoas.

You don't have to compromise on taste with vegan/gluten-free offerings. These donuts taste as good as the originals; they are so good sometimes you cannot even tell them apart. Last year, after 63 years in business, Primo's Donuts in Los Angeles made a huge change and began serving vegan donut flavors in an array of pastel colors.

Collaborations have long been a valuable marketing tool for businesses, so why not use the same principle at yours? New York City’s The Doughnut Project teamed up with Angry Orchard Hard Cider on the Angry Crisp Doughnut, which channeled the flavors of the beloved apple crisp dessert. It combined TDP’s gourmet doughnuts with hard cider for the perfect amount of juicy fresh apple notes balanced with the sweet crunchy goodness of the doughnut.

Donuts may use many different breakfast foods as toppings, including cereal, bacon, and fruit, but donuts are no longer a breakfast-only item.

Fun non-traditional “holidays” can be great opportunities for special flavors. For example, Sugar Shack Bakery in Virginia has seen significant success in its limited-time Harry Potter-themed donut, in honor of Harry Potter’s birthday. Based on the famous butterbeer beverage, the Golden Snitch donut features the taste of crème soda and butterscotch. It’s topped with gold stars and a donut hole with wings.
