The new deal will keep the 19-year-old with the Magpies until the summer of 2016.
The England Under-19 international told the club’s official website: “I’m absolutely buzzing.
“I’m loving it at Newcastle. I really feel I can develop here and I can only learn from some of the players here.
“The fans have been great with me from day one, and even though I’d spent my whole life down south until I came here, this feels like home now.”
