A real-life Willy Wonka has laid claim to making the most extravagant chocolate creation - a seven-foot-tall, five-foot-wide Easter Egg made using 352lbs (160kg) of chocolate. Jan Hansen's egg is so big that it took him three days to put together and is made from layers of Belgian chocolate which covers an iron frame. The creation had to be completed using a step ladder and is the equivalent of 1,600 chocolate bars. Jan Hansen with his 7ft tall Easter egg which he will sell off in pieces to raise money for St Barnabas Hospice . Mr Hansen hopes to raise £1,000  from the sale of the egg for St Barnabas Hospice. The giant treat, which has since been wrapped in cellophane complete with a bow on top, was made with melted chocolate which had to be tempered overnight. The 58-year-old chocolatier commissioned an iron worker to make a special frame for his egg, which was then wrapped in grease proof paper and cling film, before being covered in chocolate. Due to the nature of chocolate contracting after it cools, Mr Hansen had to add layer upon layer of chocolate using a palette knife over a three-day period. He then finished the egg off using a 'rough bark' finish. Mr Hansen, who has been in the chocolate business for almost three decades, currently has the egg on display at his shop Hansen's Chocolate House in Folkingham, Sleaford, Linconshire . Layers of chocolate cover an egg-shaped iron frame which the chocolatier had specially commissioned . In the past he has made giant Easter eggs but never one that has sized up to his current creation which  measures five feet in width. On Easter Sunday the egg is to be cracked using a hammer before it is sold off to punters who have already been sizing up the egg. Mr Hansen said: 'It is a fair size and it makes a massive difference compared to the others I have made in the past. 'It's quite fortunate that the conservatory has air conditioning and that it has double doors so we can get it out. 'The actual making was the easy part but I did have a few sleepless nights thinking about it. It was almost like chocolate cladding, I made big sheets of chocolate and put them on the side of the frame. 'It's pretty thick. Nothing tastes quite as good as Easter Egg chocolate and on Easter Sunday customers are going to take it apart and I'm going to crack it with a big hammer. It was exhausting, but it is fantastic to see the look on people's faces. 'I didn't expect people would want to buy the chocolate but it helps to raise more money for the hospice. When they see it they almost don't have to say anything you just have to look at their faces.The kiddies are lost for words, one little boy who was four and funnily enough called Charlie couldn't take it in that it was an Easter Egg. I think it scared him.' The iron frame was wrapped in grease proof paper and cling film . Mr Hansen lost his brother Cullum, 59, two years ago after he was diagnosed with a brain tumour and towards the end of his illness had need of the services provided by a hospice. He added: 'People have been very generous. I'm well on target to hit the £1,000 mark. 'Most people know somebody who has gone through the hospice and know it's a very important part of the health care. People are more than willing to support the hospice and I've felt very proud I've been able to help with this gesture.' He added: 'I've always had a sweet tooth and on a Saturday morning I used to go into the sweet shop and look at the sweets before deciding what to spend my pocket money on. 'Chocolate is my passion, I love it and working with chocolate is better than any medication or therapies. 'I say that we're so lucky working in this industry because 99.9 per cent of customers are always smiling when they walk in, and then they see this and are beaming. 'When I look at it I think "wow" but now I'm beginning to think "what can I do next" - next year I'll perhaps need a crane and scaffolding.'
