The 22-year-old, who is currently on holiday in Turkey, has told Kicker magazine he plans to sit down with the Westphalian club and discuss a new deal upon his return.
"I am very, very grateful to this club and I know what I have here," he said. "The club has helped me to mature a lot and find my way into the national team.
"As soon as I get back, I am going to talk with my family and my father will then sit down with (Dortmund's general manager Hans-Joachim) Watzke and (director of sport Michael) Zorc."
Gundogan joined the club two years ago from Nurnberg as a replacement for Nuri Sahin, who had joined Real Madrid.
Speculation has suggested Gundogan may follow the same path as Sahin, who is now back in Dortmund on loan from the Spaniards until the end of next season, but the midfielder has ruled that out for the time being.
"I am definitely going to be playing for Dortmund next season," he said.
Gundogan's current contract with Dortmund expires in 2015.
