Our Adventures With Herman The German Friendship Cake

Meet Herman the German friendship cake. He is raw, runny, yeasty smelling liquid.

He was given to me by Karen in a plastic box along with a set of instructions which read as follows: 


Herman Cake

Herman is a friendship cake which you cannot buy but can give away. Herman is alive and grows slowly but surely because of a yeasting process. It takes 10 days before you can eat him.

DO NOT put in the fridge as he grows at room temperature. You do not need a lid, just cover the bowl with a tea towel.

DAY 1:  Today Herman is given to you. Congratulations, you must have a friend. Pour him into a big bowl so he can grow. Cover him with a tea towel.

DAY 2:  Stir Herman 2 or 3 times each day using a wooden spoon. You can leave the spoon in the bowl.

DAY 3:  Stir Herman and talk to him.

DAY 4:  Herman is hungry! You must feed him with - 

  • 200ml of milk
  • 200g of self raising flour
  • 250g of sugar

DAY 5:  Stir Herman

DAY 6:  Stir Herman. He really appreciates your visits.

DAY 7:  Stir Herman.

DAY 8:  Stir Herman. Are you still talking to him?

DAY 9: Herman is hungry again! Feed him as Day 4. Having been fed, he now needs to be split into 5 equal little Hermans. Give away 4 of the little Hermans and a copy of these instructions.

DAY 10: Your remaining little Herman is absolutely starving after all that! This time feed him with - 

  • 150g of Self raising flour
  • 150g of Sugar
  • 3 Eggs
  • 2 tsp of cinnamon (optional)
  • 1 tsp of baking powder
  • 100g of fine chopped nuts, mixed fruit or chocolate chips
  • 2 Grated Apples (optional)
  • 100ml of oil (corn or sunflower)

Herman would now like to go to a hot resort, the oven will do. Preheat it to 170 degrees Celsius (which is between 3 and 4 on a gas mark oven). With everything mixed, pour him into a 7'' cake tin. Leave him at the resort for about an hour. After all this care, attention and nurturing ... eat him!!!


I'd never heard of a Herman cake before, but thought I'd give it a go. I found the fact that the mixture was left at room temperature a bit disturbing, but apparently that's OK. I put my germ OCD behind me and embraced the Herman journey...

We stirred him on days 1, 2 and 3 as instructed and fed him on day 4. We continued to stir him on days 5, 6, 7 and 8...

Time to feed him again and split him on day 9 and split him into 5 parts. One we would keep and bake and the other 4 we would give away...

I loved doing the Herman cake - even though it took up room on my work top and smelt a bit yeasty! It's something fun and different to do with kids.
