Following the launch of Maryland Mix’ems earlier this year, Burton’s Biscuit Company is now extending the brand with Maryland Gooeys Peanut.

Available in 160g packs, RRP £1.79, in cases of eight, Maryland Gooeys are peanut cookies filled with chocolate.

David Costello, head of customer category management for Burton’s, said more than two million households purchased Gooeys in its first year.

“Building on this success, the new peanut flavour will capitalise on the surge in demand for peanut butter that is seeing growth year on year,” he added.
