Recipe | Old school jam and cornflake tart

Jam and cornflake tart: a school dinner classic I’ve been meaning to make for ages!

Old school dinner jam and cornflake tart or cake traybake recipe easy quick uk recipe custard optional

What can I say? I had cornflakes to use up! I found quite a few recipes which said to use ready-to-roll, shop bought-pastry. And that’s a good option if you’re in a hurry, but making the pastry isn’t that tricky if you have the ingredients and time. I used this recipe from Baking Mad.

Jam and cornflake tart is an old school classic. Another one I think many people would have had served with custard.


For the pastry:

  • 180 g / 6.4 oz plain flour (and a bit more to dust your rolling surface and rolling pin)
  • 80 g / 2.8 oz butter or baking margarine (although butter is slightly better for pastry)
  • 30 ml / 1 fl oz cold water
  • For blind baking, you’ll need baking beans or a substitute such as rice, lentils, dried peas or beans.

For the filling:

  • 135 g / 4.5 oz golden syrup
  • 65 g / 2.2 oz butter or baking margarine (margarine is OK for this)
  • 30 g / 1 oz dark muscovado sugar (if you only have caster, granular or light brown sugar I think you can use this too and it’ll be fine!)
  • 100 g / 3.5 oz cornflakes
  • 100 g / 3.5 oz strawberry jam (seeded or jelly jam and you could also use raspberry or whatever flavour you prefer)

Pastry first! You can put the ingredients in a stand mixer and whizz them together, but I prefer to make it by hand. Use your fingers to rub the butter and flour together, then add the water and bring the ingredients together into a ball of soft dough.

Wrap the dough in clingfilm (plastic wrap) and pop in the fridge for about an hour.

While that’s chilling, grease your tart tin/ flan dish with a little butter or margarine. My flan dish is approx. 21 cm (8.25 inches) in diameter. The original recipe calls for a 23-cm (9 inches) diameter tin. So anywhere around there and you’ll be fine.

Now it’ll be ready to roll. Dust your rolling surface with flour and roll your pastry into a circle around 28 cm in diameter (about the length of a piece of A4 paper). To make this easier you can put the pastry between two sheets of greaseproof paper or under the piece of clingfilm you had it wrapped in. The pastry should be quite thin at this point – don’t worry, that’s ok!

Drape your pastry circle over your tin. Rolling it over the rolling pin or sliding it off the greaseproof paper can make this operation a bit easier. Press it gently into the tin and around the sides. If you have any large pieces of dough hanging over the sides, remove them, but don’t trim the sides to the top of the tin just yet.

Put your lined tin back in the fridge for another 30 minutes.

Pre-heat the oven to 180 degrees C (160 fan)/ Gas Mark 4 / 350 degrees F. Blind bake the pastry by putting a piece of greaseproof paper over the pastry case and filling the middle with baking beans or a substitute (I used rice), spreading the beans out to the edges of the case. Put the pastry case in the oven for 12-15 minutes. If your oven tends towards “hot” (like mine does), go for 12 minutes.

Take the tin out and carefully trim the edges of the pastry to the top of the tin using a sharp knife. Put it back in the oven for another 5-10 minutes. This should prevent the dreaded soggy bottom!

Remove the pastry case from the oven (leave the oven on) and put to one side while you make the filling.

In a large saucepan, melt the butter, sugar and syrup, stirring until you have a smooth mixture. Stir in the cornflakes and mix gently until all the cereal is coated in the liquid mixture.

Spread the jam evenly over the base of your pastry case. It doesn’t matter if the case is still warm, it will help the jam to spread.

Pour the cornflake mixture over the jam, spread out evenly and press down gently to form a compact layer without any gaps.

Put the jam and cornflake tart back in the oven for 5 more minutes. Remove and leave to cool and harden before serving.

I couldn’t wait to let it cool and set properly before cutting it because I was under great pressure from my kids to serve it. This explains why the jam ran out, as you can see in the next picture!

This old school jam and cornflake tart can also be served warm with custard. In an air-tight container it should keep for a few days.

    • I had some old cornflakes (there not a big favourite for breakfast here) and I suddenly realised I hadn’t eaten any cornflake tart in over a decade! It’s so simple and tasty. The kids certainly didn’t complain 🙂
      My mum did ask if I could post her some!!
