Bake Off winner Peter Sawkins battles robot in Maltesers cake showdown

'Great British Bake Off' winner Peter Sawkins has gone head to head with a baking robot to create a Maltesers cake.

Confectionery giant Mars Wrigley UK teamed up with Google Cloud engineer Sara Robinson, who created a Machine Learning model that used hundreds of existing recipes from traybakes to scones to develop the AI Cake.

The AI Cake - which is a ‘cakie’ hybrid between a cookie and a cake - includes both AI-generated cake and cookie elements.

The treat is topped with Marmite infused buttercream frosting after Google Search Trends revealed a top search around “sweet and salty” was “Is Marmite sweet or savoury”.

Meanwhile, 'Bake Off' champion Peter used an old recipe passed down from his mother and gave it a creative twist with some soy sauce.

He said: "I wanted to echo what makes Maltesers so moreish, so I incorporated malted milk powder and soy sauce to bring a savoury note to what is otherwise a very sweet bake.

"It was also important for me to think about creating interesting textures. There should be contrast with the crunch from the base, the rich, thick mousse and the smooth saucy caramel centre.

“Baking against the machine is a fun challenge. Not many people can say they've baked head-to-head against a Google Cloud AI.”

And Sara - Senior Developer Advocate, Google Cloud - added: “AI is a powerful tool and I love thinking about fun, new applications of it. In this case, maybe it will even inspire other amateur bakers out there to build their own creations!

"I set out to build a model using Google Cloud AI that could provide the basis for a new recipe featuring Maltesers.

"Baking is an art as well as a science - it requires finding a delicate balance of ingredients, sprinkled with a bit of magic. AI is the foundation, and human creativity combined with technology made this project shine.”

To get your baking fix this Easter, head to to get a special recipe of your own and decide who comes out on top in the battle of the bake.

Those searching for the perfect baking challenge will also be in with the chance to win a KitchenAid Stand mixer and Maltesers bundle.
