About the Recipe

Justin’s first kids cookalong uses an unlikely combination of 2 ingredients, but trust me it makes for an amazing cake with a great texture to please everyone.

Cucumber is a great source of fibre for children and by adding coconut and flax seeds it increases the amounts further.

Good quality chocolate allows for polyphenol and antioxidants to be included in the mix.


  • 195g semolina flour, or, 195g whole-wheat flour 

  • 3 tbsp flax seed
