Artisan bakery Muffin Break has unveiled the latest invention to its muffin lab – ‘Earl Grey Tea and Raspberry’.

The new product features a lemon butter icing and customers will be able to purchase the product, which retails at £2.30, from UK stores until 10 October 2016.

The creation aims to cement its commitment to customer demand for new tastes and flavours on the high street.

Muffin Break’s marketing manager Gemma Sandells commented: “Our Muffin Lab initiative has proven to be a huge success in our UK stores, with figures showing a rise in muffin sales of more than 25% in our first four months of launching the range. We are sure that this success will continue and that we will see further growth throughout the year.

“Our aim is to excite and intrigue our customers with new, innovative inventions to try out. Our limited-edition Muffin Lab creations offer our customers something different from what’s already available on the high street, creating a real excitement on what the next flavour will be.”

Muffin Break is part of a growing series of local franchisee-owned artisan bakery cafés, which bake a wide range of fresh food options on-site daily, all made from fresh ingredients.

In July, Muffin Break introduced three new flavours of milkshake to its drink range, which are made with muffins.
