  • 160 g butter (or Stork hard margarine if dairy-free/vegan)
  • 115 g light brown sugar
  • 115 g golden syrup
  • 300 g gluten-free oats


  • Preheat your oven to 160C Fan / 180C and prepare a 8 inch square tin with non stick baking paper - leave some overhang so you can lift the flapjacks out.
  • Place your butter, light brown sugar and golden syrup into a saucepan and melt till smooth. Remove from the heat and add in your gluten free oats. Mix in so all the oats are thoroughly coated.
  • Press the mixture into your prepared tin and bake in the oven for about 25 minutes until golden.
  • Remove from the oven and allow to cool in the tin to firm up before lifting out. Once completely cool, slice into squares or smaller squares for flapjack bites!


  • If you are using a 9 inch square tin your flapjacks will be thinner and need less time in the oven.
  • Remember you can mix these flapjacks up or even add some spice - maybe a tsp of ground ginger and some lemon zest?!
