Jaega Wise delves into the history, traditions and culture surrounding the birthday cake, meeting bespoke baker Adam Cox, and attending a traditional Mexican "cake smash" along the way. She'll also find out what happens when a cake historian takes on the task of baking a traditional roman-style cake, and pick up some tips for the best birthday bakes from none other than Dame Mary Berry. And there's a very special delivery for one 13 year old girl from a community network of bakers trying to ensure that absolutely all children get a birthday cake.
