The best festive flapjack

When you’re on a gluten free diet it’s important to avoid eating normal oats as these can be cross contaminated with gluten.

But using gluten free oats from the free from aisle is a great way to come up with some tasty bakes.

These gluten free mincemeat flapjacks are just an ideal bake for Christmas.

I’m talking thick and gooey golden syrup, oodles of mincemeat and sweet-smelling demerara sugar, which is why I’ve cut it into small squares to avoid a sugar overdose!

You could however serve them as bars or even triangle slices if you prefer – it’s completely up to you.

These gluten free mincemeat flapjacks are packed with all the flavours of Christmas and will leave your home smelling gorgeous as they bake.

A great gluten free Christmas bake for everyone

These gluten free mincemeat flapjacks are seriously easy to make, which is why they would be a great recipe to make with the kids.

They only a handful of ingredients too and are perfect for using up any leftovers in the cupboard.

The full recipe is down below, but for the shopping list you’ll need:

  • 300 g gluten free oats
  • 150 g unsalted butter
  • 120 g demerera sugar
  • 3 tbsp golden syrup
  • 400g mincemeat

Gluten free oats are really easy to find in the free from aisle – you can use pretty much any brand marked as gluten free.

If you don’t have demerera sugar you could use light brown sugar instead, as it will still give these a lovely taste.

Most supermarket mincemeat jars are gluten free, so you should be able to choose from a variety.

Just double check the ingredients or use the Coeliac UK food scanner app to check if you can eat it first.

Making my gluten free mincemeat flapjacks

Making these could not be any simpler – just throw it all together before baking in the oven.

First you need to make the flapjack mixture by melted the butter, syrup and sugar together, and then stirring in the oats.

Spread half of the oat mixture into a lined baking tin and press down firmly.

Then  spread the mincemeat over the top of the oats, before covering with the other half of the oat mixture, firming down and baking.

It’s really that simple – once the gluten free mincemeat flapjacks are ready, let them cool a little before cutting up.

You can enjoy them hot or cold and they keep for up to five days so you can enjoy them all week.
