As if the traditional Philly cheesesteak wasn't decadent enough, one restaurant has introduced a Donut Cheesesteak Burger. Philadelphia's PYT, which is also responsible for the Deep-Fried Twinkie Burger, launched its latest fattening creation Tuesday, which consists of a beef patty topped with chedder, steak meat, fried onions and Cheez Whiz, all placed on a split and grilled glazed donut. The eatery posted a picture of the sandwich on its Facebook page, with the caption, 'Say hello to the Donut Cheesesteak Burger. It's a beautiful, delicious beast.' 'Our hometown Philadelphia is the home of the famous Philly Cheesesteak, and living here we are surrounded by cheesesteaks. We live and breathe the cheesesteak. So we took our favorite hometown food and combined it with our PYT Burger and our other favorite food, donuts,' he said. Mr Up estimates - conservatively - that the diet-busting burger comes in at 1,400 calories. 'It is the perfect balance of sweetness and saltiness between the fresh donut and the juicy beef and cheese.' 'I was the first one to try it and I was in heaven,' he says. 'It is the perfect balance of sweetness and saltiness between the fresh donut and the juicy beef and cheese,' he adds. The Donut Cheesesteak Burger costs $15, and is available for the remainder of summer. PYT, known for its sweet-and-savory novelties, claims to be 'home to America’s craaaziest burgers.' In fact, the restaurant already features an item on its menu called 'The Doh! Nut,' which is described as a beef patty, American cheese and chocolate-covered bacon on a glazed donut bun. Past offerings have included a deep-fried PB&J beef burger and the deep-fried Twinkies burger.
