The giant 'Fruit & Nowt' bar was a gift from the chocolate giant after 10-year-old Freddie wrote to Cadbury's to tell them he didn't like nuts in Fruit & Nut bars, and would prefer 'Fruit & Nowt'.
Freddie's letter said: "Dad is from Yorkshire and I think it would sell very well up north where my grandparents live. It would be the same as Frui & Nut just without the nut.
"If you like my idea and would like to make it, I would like to receive 1% of your profits for coming up with my idea and 4% for my selected charity, Barnardos.
"Yours sincerely, Freddie Drabble. Entrepreneur."
The enterprising youngster, who lives in Kent, was then thrilled to receive this super-sized bar of Cadbury's Fruit & Nowt in the post - although sadly, the bar is a one of a kind and won't be making it to store shelves any time soon.
Freddie's grandmother Janet, from Ashfield Close, Sheffield, said: "We were so surprised to hear back so quickly. Freddie was absolutely thrilled to bits"
