    Golden syrup is a clear, sparkling, golden-amber coloured, sweet


  1. Heat oven to 200C/180C fan/gas 6. Tip the plums into a bowl. Toss with the spice, 50g of the sugar and a small pinch of salt, then set aside to macerate.

  2. Gently melt the butter in a saucepan. In a large bowl, mix the oats, flour, walnut pieces and remaining sugar together, making sure there are no lumps of sugar, then stir in the butter and golden syrup until everything is combined into a loose flapjack mixture.

  3. Grease a square baking tin about 20 x 20cm. Press half the oaty mix over the base of the tin, then tip over the plums and spread to make an even layer. Press the remaining oats over the plums so they are completely covered right to the sides of the tin. Bake for 45-50 mins until dark golden and starting to crisp a little around the edges. Leave to cool completely, then cut into 18 little bars. Will keep in an airtight container for 2 days or can be frozen for up to a month.

I use less butter and sugar but keep the other amounts the same and I leave it overnight in the fridge before I cut into slices. The recipe says it will keep for two days but, I've found it keeps well for one week. Very happy with this recipe.

Like many others I was trawling through some old Good Food magazines and came across this recipe. Lovely moist flapjack, the plums are a lovely addition but the butter content is definitely too much and I would reduce it by 100g next time. Difficult to slice neatly when fresh, I'm going to leave it in the fridge overnight to see if that helps. A very nice change to ordinary flapjack, very Autumnal!

The amount of sugar and fat in child-friendly recipes is much too high and goes against the advice we are given to avoid obesity in children.

Delicious, even the kids ate these and they would normally refuse anything with plums! I realised a bit late that I didn't have enough oats so cut the other ingredients by half, but the whole amount of plums. Oh and I used almonds instead of walnuts. They are a bit soft and crumbly, hoping a night in the fridge will firm them up. However with cream, custard or ice cream they are just like mini plum crumbles.

Made these for a picnic, just as the recipe said. Could not fault the recipe. Very nice indeed. Not for anyone counting calories!!!

Very good! Left out around a third of the plums though as otherwise think it would've been too soggy!

I made this yesterday and it has gone already! My boyfriend had 4 pieces in quick succession! It is really nice and dense, it binds together more than normal flapjacks made with oats, butter and syrup, so it has a slightly more cakey texture? I sandwiched it together with jam instead of plums but still really nice, although very sweet! Would definately make again.

I also followed the comments and put in 100g less sugar and butter. Used mostly demerara sugar as well as I ran out of muscovado. They turned out very tasty indeed! The mixed spice with the plums is lovely, and compliments the walnut beautifully. I cooked it in a round, silicone cake dish, as that was what I had on hand and cut it in cake-wedges for desert. It held together very well. With the fruit layer in the middle still slightly warm it made a decadent desert with a scoop of vanilla ice cream.

I liked this recipe. Nice flapjack but I followed the comments and put in 100g less sugar and butter, and it was just lovely. Had a glut of plums so nice for variety from jam!

Fantastic flapjack. I've been looking for a recipe that is very flexible to use , the butter is just right and is delish warm from the oven with custard. However taking out 100g of butter makes it a little firmer to hold. You can use any fruit filling or even chocolate chips, because they are in the middle of the mix they don't burn. Won't be using any other recipe, hope you enjoy it too!
