This time, he's in for a treat. He's on a challenge to hit the gold standard of baking as he creates a table of cakes for the Glamorgan federation of the Women's Institute. For Matt, this is a Great Welsh Vegan Bake Off like no other as he bakes to impress and convince not only the WI judges, but an expectant crowd of cake-lovers at the annual Gower agricultural show. He hopes to show that vegan cakes can be as tasty, sweet and creamy as their non-vegan alternatives. But will Matt's cakes uphold the impeccable reputation of the WI bakers? With that kind of pressure, there's no room for soggy bottom!
