The deal will see a Scunthorpe United exclusive cookie be available, as well as other favourites from the Cookie People range.
Head of Hospitality and Events Kelvin Stanford said: "I’ve always been a big fan of their products, and it’s great to support an independent Scunthorpe based company as they continue their expansion.
"The inclusion of cookies on a matchday will further enhance the offering to fans as we look to create the best matchday experience possible."
Andy from the Cookie People added: "As a long-standing supporter of the club, it’s such a privilege to be involved. As a boy I would have loved to have played for the Iron, it wasn’t meant to be so this is the next best thing!
"We can't wait to see the fans inside the ground eating our cookies and seeing the team win week after week! Toni has loved creating a unique cookie for Scunthorpe United, and we hope the fans love it too!"
