The 37 year old will continue to provide back up for Paddy Kenny who is currently the first choice goalkeeper at the Blades. Bennett has put pen to paper and signed a new contract with Sheffield United.
He said: "I'm really pleased to be staying and I aim to provide real competition for Paddy as well as back-up because I felt that I did well last year when I came in."
His gaffer Kevin Blackwell commented: "Benno is a top professional who is very reliable and did ever so well when he came in for several important games last season such as those with Leicester and Stoke."
