The Bisnut

The weirdest thing about this mashup is the name. Carl's Jr. apparently decided that if the croissant-doughnut hybrid Cronut was a hit, then the biscuit-meets-doughnut Bisnut should be as well. The actual product, currently being tested in California, is less exciting than its moniker: essentially, a biscuit shaped like a doughnut, with icing and sprinkles.


Doritos Locos Tacos

Before the Cronut and the Waffle Taco, Doritos Locos was the freshest mashup in the food world when it was released in 2012. Taco Bell released sold more than a billion Doritos Locos Tacos in the first year it was available. The taco chain is still releasing new flavors, with Spicy Chicken Cool Ranch as a recent limited time offering.

Taco Bell jumpstarted the quirky food trend in 2014 with its breakfast roll out in March. The chain's first foray into breakfast offered items including breakfast burritos and AM Crunchwraps, but what grabbed the public's attention was the Waffle Taco.

"I'd rather have people have an opinion than no opinion. I don't want to be in the land of same-ness," Taco Bell President Brian Niccol told Entrepreneur.com regarding the launch. "I'd rather be in the land of, you either love it, or you can tell me why you don't love it. What I don't want is bland."

Calling KFC's Chicken Corsage a fast-food innovation is a bit of a stretch, seeing as it's just a classic drumstick attached to baby's breath flowers and a ribbon. However, as the chicken-chain's commercial for the product hit 645,000 views on Youtube in the product's week, it is certainly getting the attention of chicken hungry high schoolers.


Specialty Chicken

As chicken became an increasingly hot commodity in 2014, Domino's beefed up offerings with the Specialty Chicken. The offering substitutes fried chicken for dough as the base for pizza toppings, with options including Crispy Bacon and Tomato, Spicy Jalapeno and Pineapple, Classic Hot Buffalo and Sweet BBQ Bacon.

Pizza Cake isn't on the market – yet. The mega-pizza won Boston Pizza's Pizza Game Changers campaign in April.
