Tyias Browning and John Lundstram have signed two-year professional contracts with the Blues.
Both are highly rated by Everton's Academy coaches and were handed their first pro deals after they turned 17.
Browning is a powerful right-back who can also operate at centre-half. Lundstram is a central midfielder.
Both players were integral to the Club winning the national Academy title, while also featuring for the Reserves during the 2010/11 season.
Earlier this week James Wallace and Aristote Nsiala signed new one-year deals.
Midfielder Wallace, a product of the Toffees' academy, spent the end of last season on loan at Stockport.
He has one senior appearance to his name, featuring in the Europa League two seasons ago.
Wallace, 19, impressed at Edgeley Park and was handed the captain's armband towards the end of his stint.
"I am delighted to sign a new deal at the Club," Wallace told evertonfc.com. "I am made up it is sorted and I am just looking forward to pre-season."
Nsiala, a central defender who can also operate at right-back, is another youngster who spent time in League Two last season - with Stockport's Cheshire neighbours Macclesfield.
The 19-year-old has been on the Toffees' bench this season but is yet to feature for the first team.
"I am happy, and dead excited - I'm happy that I have been given another challenge," he told evertonfc.com. "Getting on the bench and scoring while on loan have been ups for me this season and I am looking forward to next season."
