In December 1932, Cook was transferred to Everton for £3,000. It was a surprise move at the time and he is considered one of the first high-profile players to leave Celtic mid season for another club. Cook stated that the reasons for the move were financial. He enjoyed immediate success at Goodison Park, helping Everton win the 1933 FA Cup Final with a 3–0 win over Manchester City at Wembley. On his death in December 1992, almost 60 years later, he was the last surviving player from that team. A League championship win followed in 1939, but the outbreak of World War II prevented Everton from building further on this success. In his time at Everton, Cook made 250 appearances and scored six goals.
