It may be one of the plainest chocolate bars in the supermarket but a humble Cadbury Dairy Milk has been crowned Britain's favourite chocolate bar, according to a new study.

Chocolate lovers munch through a whopping 22 bars of Dairy Milk per person in just one year, and 1,317 over the course of their lifetime, a survey found based on the projections of 2,000 UK adults.

Snickers - the classic chocolate, peanut and caramel bar - was voted the second most popular in the poll.

The study, by savings website Vouchercodes.com, found that the average Brit will eat nearly 1.5 tonnes of chocolate worth more than £12,000 in their lifetime.

However they prefer a simple Cadbury Dairy Milk bar over Rolos, a creamy nougat MilkyWay, a caramel-chocolate Boost or crunchy caramel-filled Munchies, which were voted the least popular of 30 favourite chocolate bars.

The research found that a typical adult will tuck into 7,004 bars on average in their lifetime, including 1,642 dark chocolate, 1,425 white and 3,934 milk.

Four in 10 Brits admit to being a chocoholic, according to the study, while six in 10 would 'hate' to live in a world without the cocoa-based treat.

It also emerged Brits will crack into a total of 104 Easter Eggs during their lifetime which works out as 13kg of chocolate overall.

It's not just bars and Easter eggs we're munching our way through, as the average aduly will also eat 668 slices of chocolate cake in their lifetime.

Almost 3,000 mugs of silky hot chocolate will be downed, weighing in at 943kg.

This is how much of each treat an average adult will eat in their lifetime

And they'll nibble away at 8,719 or 92kg of biscuits or cookies containing chocolate over their lifetime.

Eager to get their 'fix', 12 per cent of people have pinched chocolate from colleagues at work and 35 per cent have 'borrowed' it from their partner.

But most shockingly of all, 28 per cent have nabbed it from their own children.

Anita Naik, lifestyle editor of VoucherCodes, said: 'Although more than one third of nation say chocolate is their absolute favourite food, I was still surprised to learn our chocolate obsession will cost each of us £12k in a lifetime.

'It's clear that despite bar sizes shrinking and prices going up, we Brits are still happy to spend our cash on a sugary pick-me-up.'
