The former taxi driver has signed a book deal to write the "true story" about the `Rehab` hitmaker - who died in July aged 27 - by penning `Amy, My Daughter` to help him deal with the passing of the singer.
He said: "I feel that I need to write this book to tell the true story of Amy and to help with my personal recovery."
All proceeds from the book - which is set to be released by publisher HarperCollins next summer - will go to The Amy Winehouse Foundation, which was launched last month on what would have been the late singer`s 28th birthday.
Mitch - who set up the charity alongside family and friends to help vulnerable young people - added: "I also want to raise as much money as possible for Amy`s Foundation, so all proceeds from the book will go directly to help children who are disadvantaged through illness and substance addiction.
"I believe that through Amy`s music, her foundation, and this book, her name will live forever."
HarperCollins described the tome as a "heartfelt and revelatory memoir" - and Nick Canham, the editorial director of Harper Non-Fiction, explained: "The strength MitchWinehouse has shown over recent months is truly admirable.
"His desire to create a definitive account of Amy`s life, that will solely benefit the foundation he has established in her name, is something that we are incredibly proud to be part of."
Mitch is set to sing a number of songs from his new album `Rush of Love` at a charity brawl to raise funds for The Amy Winehouse Foundation at Proud2 in London`s The O2 on October 22.
It will be his second performance since his daughter`s death after he sang at the Big Reveal charity show at the London Hilton hotel in Park Lane last month.
