Notes

  • *1 I used olive oil for the updated photos, but you can use sesame seeds oil or other oil.
  • *2 I used homemade granola but you can use store bought granola. 
  • *3 For the update, I did not use a square tin but used "Italian muffin cups" bought from a local Daiso shop. 
  • *4 If you don't have a handheld mixer, you can just use a whisk. 
  • *5 try not to overmix the batter. 
  • *baking time is indication only. Insert a skewer and if it comes back clean, cake is baked.
