The range features classic desserts flavours: sticky toffee pudding, lemon meringue pie, rhubarb crumble or apple pie and custard. They are suitable for vegans and vegetarians.
Swizzels latest creation was designed by the brand's fan Tracy-Jane Fielding who won the competition for the best new product idea. She came up with the Great British Puds concept to transform the iconic British desserts into unique chew bars.
Tracy worked with the Swizzels team throughout the product development process.
Commenting on the launch, she said: "I've been a fan of Swizzels for as long as I can remember, so having the opportunity to put my own sweet ideas forward to the team was a privilege in itself."
She added: "The inspiration for my invention came from years of experience working in restaurants and my observations that classic British puddings continue to be hugely popular."
Tracy says that it's overwhelming to see her products launching in the shops across the country.
"Now that my very own sweet invention is actually hitting the shelves of supermarkets and stores nationwide, I am completely overwhelmed," she said.
"It has been a pleasure to be part of the full development process and I am delighted with the finished result," she added.
Swizzels MD Jeremy Dee said: "Since the announcement of our Sweetest Invention competition winner, the team and our winner have been hard at work developing Great British Puds."
He added: "We are delighted to finally be able to launch them for fans to enjoy. Our mission remains to lead the way with new, ingenious sweet inventions, so involving our dedicated fans in this process and receiving their creative ideas is a great way to achieve this."
