Traditional Flapjacks

I’m a huge fan of comfort food on rainy days and this traditional recipe delivers on the wholesomeness. Traditional flapjacks are just as good gluten-free and can be combined with chocolate, fruit or nuts to create the flavour you want. Take a look at the recipe below for a coeliac-friendly flapjacks that you won’t believe are gluten-free!

Flapjack brings back all the school feels. I remember it being on the menu several times a year severed up with a dollop of pink or yellow custard. The recipe is plain and simple but the flavours really do deliver a warming wholesome dessert for rainy days!

Which substitutions are possible?

Golden Syrup- I prefer to use a good dollop of Golden Syrup but honey or another sweet syrup can be used with a 1-1 substitution

What equipment do you need for these flapjacks?

  • One deep square baking tray, I use the standard traybake size from Pyrex such as 25×25
  • Baking paper
  • Offset spatula

Tips & Tricks

I use grams for weighing almost all of the ingredients in my recipes as it is what I am most used to when cooking and baking on a daily basis. I use measuring cups for simple ingredients such as spices or smaller amounts as it can be much easier to measure. I would recommend sticking to what the recipe suggests as there is no guarantee that converting into cup measurements or vice-versa will have the same outcome.
