Sue Maree P Baking Tips

  • Seeds – if you don't want seeds add 50g of extra oats instead.
  • Vegan – for a vegan flapjack or oat slice, swap out the butter for a non dairy spread or oil
  • Sugar – if you prefer a sugar alternative swap out for honey, agave nectar or maple syrup
  • Don't over cook otherwise it will be too crunchy to eat
