  • finely grated zest of 1 large orange



    One of the best-known citrus fruits, oranges aren't necessarily orange - some varieties are…

  • 3 tbsp fine-cut orange marmalade


  1. Preheat the oven to 180C/gas 4/fan 160C and generously butter a 28 x 18cm shallow baking tin. Melt the butter, sugar and syrup over a medium heat, stirring all the time. Take off the heat and stir in the oats, walnuts and orange zest. The mixture should be quite soft.

  2. Tip the mixture into the baking tin and level it off. Bake for around 30 minutes or until the edges are golden brown but the centre is still a little soft. Remove from the oven and mark into 12 pieces while it is still warm, cutting down halfway through the mixture with a sharp knife. Leave to cool.

  3. Heat the marmalade with 1 tbsp water until it becomes syrupy. Brush this glaze over the flapjack mixture and leave to cool before cutting into 12 pieces. They will keep in an airtight tin for up to a week.

After looking at the comments below, I reduced the sugar by 1/3, replaced 50g of the golden syrup with treacle, used 100g sultanas instead of walnuts and mixed the marmelade in with the golden syrup (just two tablespoons of a cheap jar) rather than use it as a glaze because I didn't want them to be too sticky to transport to work. I was too lazy to zest an orange. I used a standard 23x28 cm roasting tray with a silicon liner.End result was delicious. Next time I might reduce the sugar by half and increase the treacle:syrup ratio.

The best, tastiest flapjack around. I am always being asked to make for birthdays, tray bake sales etc. I must have had made it ten times now, love it. Thank you.

This recipe is the horriblest recipe I have ever made for flapjacks. There gooey, sticky, can't get them out the tin & yes I did follow recipe. My advice bake something else.

Really easy and tasty. Delicious without the marmalade as you can taste the zest. Only problem is there is an error with the tin size. It says 28x8cm which is really narrow - don't even know if that exists and I can't see how you'd get 12 slices from it. I used a 20x20cm one which gave me 12 chunky slices and cooked perfectly in the time.

Took on board some of the earlier comments... Used half the amount of sugar and put the marmalade into the mixture rather than adding on top after cooking. The outcome was delicious and not overly sweet. Baked in a standard tray bake tin, roughly 23x32cm. Perfect.

easy to make, but it was too rich and too sweet for us.

yummy!!! easy to make and will incorporate the marmalade next time........ only negative is that i would recommend a slightly deeper tin but that maybe due to my equipment. a must bake

I made these today, with just half the caster sugar and I melted the marmalade in with the fat/sugar/syrup mixture. I have to say they are absolutely scrumptious! Definitely sweet enough. If you like nuts then double the walnut amount. 50g in such a large mix gets totally lost but its all down to preference. Shall be making these again :)

This had become a family favourite - it gets eaten before I get chance to put on the marmalade. I actually included the marmalade in the mixture the first time I made it as I didn't read the recipe properly, and it was also lovely.
