The pizza is billed as a "fun treat to share" and features ten mini burgers topped with mozzarella embedded around the crust. A large serving contains ten 288-calorie slices, and costs £2.50 more than a traditional deep pan.
Just half the pizza is enough to account for 72 per cent of a woman's daily allowance of 2,000 calories. The chain's latest "crust innovation" follows others such as the Hot Dog Stuffed Crust and was first launched at its restaurants in the Middle East.
Tam Fry, a spokesman for the National Obesity Forum, said: "If I had a family of ten and we had all been on a brisk five mile walk in the rain and lost our picnic on the way, I might just buy one to ensure that everyone got a warm something inside them.
"For your average family, however, divvying this pizza up in any other way is unreasonable and irresponsibly marketed."
Pizza Hut is one of a number of restaurant chains that has signed up to the Department for Health's "Responsibility Deal", a commitment to publish calorie counts, cut levels of salt and trans fats and promote healthier eating.
Speaking yesterday, Pizza Hut insisted the "delicious limited edition" cheeseburger pizza was part of a wide ranging menu which also included pastas and salads.
In a statement the chain said: "We are committed to producing a wide range of fresh, high quality food which can be enjoyed as part of a balanced diet.
"In facy every pizza in our restaurants comes with free, unlimited salad." The chain refused to comment on how the launch may affect its standing with the Department for Health.
The launch comes just weeks after Nestle unveiled one of the most calorie laden chocolate bars in Britain, the Nestle wonka bar. The bar, contains up to 555 calories per 100g, more than a Mars Bar, Haagen Dazs ice-cream and twice as much as a Big Mac burger at McDonald's.
