When you have allergies, the hardest things to find are snacks you can have on the go. So we devised this delicious banana and date flapjack recipe for you to enjoy. Originally these were sold on Amazon UK and in shops in Manchester. Unfortunately production costs were too high for us to continuing supplying them to shops, but we didn’t want you to be without! SO we decided, what the heck! We’re going to release the recipe!

sugar free dairy free wheat free gluten free egg free vegan banana and date flapjacks with oats

The name Wonderjack was actually devised by my Mum. She said they should be called Wonderjacks because they are flapjacks but they are free from:

  • gluten
  • wheat
  • nuts
  • peanuts
  • eggs
  • dairy
  • refined sugar
  • soya
  • suitable for vegans and vegetarians

Free from pretty much everything, but flavour! Therefore she said, they are suitable for everyone making them wonderful and full of wonder. And so Wonderjacks were born.

We hope you enjoy the recipe! They are really easy and so quick to make, quick to eat too…Better watch out! 😉
