The left-back, 19, made 25 appearances for the League One outfit as a loanee last season and his return to Griffin Park was confirmed on Wednesday.
"I am very pleased to welcome Jake back to Brentford," said Bees boss Uwe Rosler. "He fitted in very well to our squad and our style of play last year.
"He knows what we do at Brentford and that will be an advantage to all of us. Jake comes to us on a youth loan but has a lot of experience at our level."
