A competitive eater who moonlights as a model has baked her cake and eaten it too - scoffing the entire thing in just under seven minutes.

Kiwi Nela Zisser, filmed herself patiently baking the scrumptious lemon cake before smothering it with whipped cream and demolishing it with a spoon.

The 24-year-old took just six minutes and 20 seconds to polish off the decadent treat, making it look like a piece of cake.

A minute into gorging on the cake, Zisser pauses briefly to comment on her baking skills.

Kiwi Nela Zisser, filmed herself patiently baking the scrumptious lemon cake before smothering it with whipped cream and demolishing it with a spoon.

'Now this is a really good cake,' she says before forking in another mouthful with relish.

Halfway through the attempt she stops to consider whether maybe she should take her time to enjoy the cake.

Deciding better, she scoops up another massive spoonful and continues her efforts.

After finishing the cake and all-but licking the plate clean, a grinning Zisser describes how much fun she has just had.

'That was actually a really, really good challenge,' she says.

'It was a really delicious challenge to film and it was really fun because I got to get into the kitchen again to do some baking.'

Zisser is a YouTube sensation who regularly clocks upwards of half a million views on her eating videos.

Other stunts of hers include the 100 cheeseburger challenge, eating 22 Big Macs in a sitting and a eating five foot Subway sandwhich.

Earlier this year she travelled to the United States to compete in the Nathan's Famous Fourth of July International Hot Dog Eating Contest - placing a respectable seventh.
