Gluten Free Flapjack Oat Bars

Makes 12 oat bars

Flapjacks are a classic traybake made with oats. If you don’t have demerara sugar to hand simply use white sugar. For an oat bar with a hint of spice, you might like our Gluten Free Oat Parkin.

Free from Gluten, Egg, Soya, Wheat, Nuts

Sick and fed up with GF biscuits and over priced off the shelf GF treats - try these! Absolutely spot on, nice & easy. Personally I blend the oats a little and add some ginger and cinnamon, drizzle a little choccy on top - Perfect -Thanks dovesfarm for the idea!

On the advise of one of the other reviewers I reduced the sugar to 80g, if I did the recipe again I’d reduce it to 60g as it’s still plenty sweet enough

Thank you so much for your review.  This was an error and the recipe now has reduced sugar at 75g. Best wishes, FREEE.

Lovely flapjack, easy to make. Held together and just a touch of stickiness. No complaints from the taste testers it disappeared before my eyes!

I made Gluten Free Flapjacks for the first time this afternoon. Easy recipe, chewy and absolutely delicious. Will take the advice of a previous reviewer and adapt the recipe with additional ingredients. Maybe sunflower or sesame seeds for a little more texture and nutty flavour. Gradually working my way through the Freee recipes. No disasters yet, although I have probably tempted fate by typing the sentence:)
