Ingredient Substitutions

  • Butter – you can switch for coconut oil if you would like a dairy-free version.
  • Honey – you can swap for maple syrup.
  • Ground almonds – you can swap for Gluten-Free Plain White Flour or even regular All Purpose Flour
  • Blueberries – swap for raspberries, sultanas or a handful of mixed dried fruit.

Cooking Tips

  • Wait until your porridge has completely cooled before beginning making the cake. You could even leave it in the fridge overnight and make it the next day.
  • If your porridge is already flavoured with cinnamon or vanilla then just reduce the quantities of the flavourings slightly so it doesn’t get overpowering.
  • Stir the blueberries through gently so they don’t break up in the cake mixture.
  • Allow the cake to rest for 5 minutes before removing from the cake tin.
