The Krispy Kreme doughnut burger — aka the Gut Buster — is about to crash land on the menu of a suburban Perth burger bar.

The fried bacon, cheese and beef patty are wedged between two original glazed Krispy Kreme doughnuts. And the calorie count is 1500 — the equivalent of three Big Macs, or almost the entire recommended daily calorie intake for women and more than half the recommended daily intake for blokes. (In other words, you’d have to run for two hours to burn it off.)

Johnny Wong, owner of Johnny’s Burger Joint — a must-stop-shop for big-eatin’ lip-lickin’ truckies in southern suburban Canning Vale — posted his invention on Facebook this week with a promise to have it on the menu for a short time after Christmas.

The 22-year-old had seen the bizarre dinner-dessert combo at a fast food fair in the US but was inspired to make one after Krispy Kreme launched in Perth in November.

Mr Wong’s no stranger to serving up New Jersey-style bulldozer burgers, with his “challenge burgers’’ including a 12-spoon-chilli-topped Demon’s Revenge (“not for the faint-hearted’’) and the Burgerzilla — a breakfast, lunch and dinner all-in-one that includes FIVE meat patties and SIX slices of cheese ($40 BTW).

Pass the Alka-Seltzer.

A Perth fast food joint has created the most unhealthy burger our city's ever seen. Delivering 15-hundred calories the cheese, bacon and patty are wedged between two Krispy Kreme doughnuts.

“You only live once, try it,” Mr Wong urged of his new sugar-coated offering.

So what does the sweet, fatty, salty, novelty marketing-quirk taste like?

“It’s really, really juicy and tastes better than it looks’’ a brave guinea pig told Nine News at a sneak sitting.

Australian Medical Association president Michael Gannon, however, was less impressed, labelling the burger a “heart-attack waiting to happen”.

Eat one and you will be ingesting the equivalent of one roast turkey dinner, a serve of Christmas cake, three alcoholic drinks, one mince pie plus two shortbreads.

Hold the fries.
