Peter, who won the Bake Off late last year, has secured a deal with Scotland's Black and White Publishing, to write a cookery book titled Peter Bakes.
Peter is from Edinburgh and currently a student studying accounting and finance at Edinburgh University.
At aged 20, Peter was the Bake Off's youngest winner and spent half his life watching the show. He has watched every series since the first one in 2010, and has been baking seriously since he was 12 years old.
Peter actually applied for the 2018 series, getting a “few rounds” into the application process, but he’s since said he’s glad he wasn’t successful, with the extra time meaning he was more prepared for this year’s show.
The Scot liked to include native ingredients in his creations – such as berries, whisky, oats and honey – whenever he can so fans can possibly expect more of this in his book.
Speaking about appearing on The Great British Bake Off, he said: “[I was] absolutely chuffed! It was a long and uncertain path getting to the tent.
“I was just so excited to get baking in the tent and fulfil this amazing dream.”
In Peter Bakes, Peter will detail how to recreate some of his recipes, and also offer gluten free options - as he did on the TV programme (Peter's brother brother Andrew has a food intolerance).
Readers can also expect tips and hints on growing confidence and skills in baking.
Speaking to The Bookseller, Peter said: "I am so excited to share my passion for baking in this book. I want readers to find the fresh ideas inspiring and the classic techniques valuable.
"I really hope the book proves to be enjoyable and useful, and that everyone’s copies at home will be well-thumbed and splattered with cake batter in the years to come."
It is expected that Peter Bakes will be released in October 2021.
