2) Ring of Fire

The Ring of Fire pairs heat with sweetness via cinnamon sugar and cayenne pepper topped with a dried red chili pepper garnish. It's a staple at Voodoo Doughnuts, which has locations in multiple states primarily on the West Coast.

4) Sausage Donut

Using an otherwise traditional donut (without the hole) as a bun, the sausage donut features a cocktail sausage with sliced onion and redcurrant jam sauce on the inside. This one-of-a-kind donut sandwich from master confectioner Florian Perkmann—who's known for pushing the boundaries of experimentation—debuted in early 2023.

5) Raspberry/Bailey’s Liqueur Berliners

Kreyenbuhl bakery in Switzerland celebrated the worldwide release of the COVID-19 vaccine in 2021 in style with jelly-filled German donuts with syringes sticking out of them. The hollow donut and visually striking presentation turns the donut classic on its head by allowing customer to “inject” raspberry or Bailey’s filled syringes into the dessert before eating them.

8) Donut Xo

Meet the Donut Xo, from the mind of Three-Michelin-Star Chef Dabiz Muñoz. The vanilla donut with toasted buttercream filling, a hint of spiciness, and a striped dark chocolate topping hit the shelves at Carrefour in Spain. To make it more enticing, the price for such an elegant donut is only $1.69.

9) Pizza Donut

Massachusetts-based Donut Villa is known for its modern interpretation of the classic American diner and has been putting a modern twist on the classic donut by topping it with marinara sauce and mozzarella cheese. Donut purists may call this a bridge too far, however, this is a not-to-miss treat if you’re in the Cambridge area for breakfast or dinner, depending on how you look at it.
