2 ingredient chocolate ganache from 'Great British Bake Off' winner

After another intense season of "The Great British Bake Off," the series' youngest champion shared what made his historic victory so sweet, along with a simple two-ingredient recipe that will help any home baker feel like a pro.

Peter Sawkins joined "Good Morning America" from his home in Scotland after making history as the youngest baker to earn the title at just 20 years old.

"It was a childhood dream come true. I've watched the bake off for half my life and I managed to win it. It was crazy," he said reacting to the victory. "It was absolutely amazing."

In a season unlike any other, competing under lockdown in "a bakeoff bubble" due to COVID-19 precautions, Sawkins said even his roommates didn't know how the finale was going to play out.

"My flatmates did not know -- it just made the whole experience more fun cause I could watch with them in the flat and they had the excitement of not knowing whether I stayed or left. Then we had big cheers in the final when they were relieved to see me win it."

Sawkins said that even amid quarantine the competitors "had a great time -- there was so much energy, the crew was amazing -- we all had a blast."
