The Toffees were much better after a humbling loss to Minnesota United in America earlier this week.
And it will give Frank Lampard a clearer idea of the team he wants to face Chelsea in the opening Premier League fixture of the new season on 6 August.
Everton made an excellent start and took the lead in just the sixth minute through a fine Vitalii Mykolenko volley.
Then things got even better for the Toffees as Salomon Rondon beat the offside finish and picked out Tom Davies, who headed home.
Lampard’s side dominated the opening 45 minutes but saw their advantage reduced moments before half-time when Gary Madine netted for Blackpool from close range.
Everton restored their two-goal lead inside two minutes of the second half when Dele Alli netted from close range.
The Seasiders refused to go down fighting, though, as Blues old boy Callum Connolly headed home.
But the visitors would add a fourth through a deft Dele finish with 26 minutes remaining.
