Boiled Chocolate Cake – Family Favourite

Mum has been making this family favourite forever. Tried and true. It’s the only moist chocolate cake the kids and grand kids love. This recipe was given to her by my Aunty, 40 years ago. In turn it was given to my Aunty by a Home Economics teacher.

By chance, many moons ago, she also found it in the Women’s Weekly Chocolate Cakes book while at a grocery shop. She opened the book and saw the word ‘family’ in the title. When she read further, she realised it was the same recipe. My family of seven grew up on this ‘Boiled Family Chocolate Cake’. Our ages span from 42 to 55, which gives you even more of an idea how long it’s been around.

  1. Ooooh yum! Our family favourite is the ‘Simplicity chocolate cake’ recipe from Nursing Mothers Association of Australia cookbook. It’s decades old! We’ve added a dollop of yoghurt to the recipe for moistness. I love your icing recipe. I’ll give that a try next time 🙂

  2. My mum used to make this cake a LOT when i was a kid, but usually a huge rectangle shape. She iced it with chocolate icing and sprinkled with coconut. She used to make it for her work mates, and my brother would always complain that she cut the crusts off and we got that, then she took the best bit to work!
