Cornflake Tart

Cornflake tart recipe

This cornflake tart is so simple and nostalgic. A firm favourite in our house, and one of my husbands all time favourite desserts. It’s the perfect combination of sweet and buttery flavours; a homemade shortcrust pastry, filled with strawberry or raspberry jam and layered with sticky golden syrup cornflakes – delicious!

The tart is lovely served with custard or ice cream – or alone is lovely, too! I know it looks like there’s alot of steps below to make it, but once the pastry is done it’s very simple (and using homemade pastry makes all the difference vs shop bought).

I also have recipes for old school cake and chocolate crunch, if you’d like to take a trip down memory lane, check them out.

How to make a cornflake tart

Step by step photos and instructions – scroll down for the full ingredient list and printable instructions

1. Begin by pre-heating your oven to 180C

preheat oven to 180c

2. Measure out the 200g plain flour and 100g unsalted butter, and cut the butter into small chunks

3. Then use your hand (or a food processor) to mix these together, it will come together to form a chunky breadcrumb texture

4. Then, slowly add in COLD water, 1 tbsp at a time (you’ll likely need 3-4 tbsps) and mix with a spoon until it starts to come together, then, use your hands to mix it –

5. After a moment of hand mixing, it should form a ball of dough – like this:

6. Then rub your tart dish with butter (I tend to put my hand inside a sandwich bag to do this, it keeps your hand clean)

7. Next, lightly flour a clean surface and place your dough on it, turn the dough over so both sides are floured

8. Then roll your dough until it’s wide enough to cover your tart dish

9. Place the pastry inside the dish, poke the bottom with a fork (so the base doesn’t puff up too much during the blind bake) and trim the edges of pastry, leaving some overlapping the lip of the dish

10. Scrunch up some parchment paper / baking paper and place it into the tart base

11. Fill with baking beans – or, if you don’t have baking beans, use dried pasta or rice

12. Then, put the tart base in the oven for 15 minutes on 180C

13. Whilst the base is baking, measure out your 100g of cornflakes

14. And measure / combine the 50g butter, 130 golden syrup and 30g light brown sugar, pinch of salt, into a large saucepan

15. Heat on a low/med heat until all is melted and combined (stirring often) then immediately turn the hob off

16. Pour in your cornflakes and stir so they’re coated in the sticky mixture, set aside

17. After 15 mins of baking – remove the tart base from the oven, and remove the parchment paper and baking beans (bin those)

18. Trim the pastry edge so it’s flush to the dish, using a bread knife is easiest (this is just so the tart looks neat when it’s cooked, so is optional if this is a step you’d struggle with

19. Then spread the 130g jam into the base (you can add more jam if you’d like)

20. And finally, top with the sticky cornflake mixture, use a spoon to push it down into a flat layer

21. And bake for a final 5 minutes! Once it’s baked allow it to cool for 20 mins before cutting (to allow the jam to set) and enjoy!

Cornflake Tart

cornflake tart recipe

A deliciously nostalgic cornflake tart, made with homemade shortcrust pastry and a thick layer of strawberry jam. This is a super easy dessert which the whole family can enjoy, and the kids can get involved with making it, too.


For the pastry:

  • 200g plain flour
  • 110g butter
  • 1-3 tbsp cold water

For the filling:

  • 130g strawberry or raspberry jam
  • 50g butter
  • 130g golden syrup
  • 30g soft light brown sugar
  • 100g cornflakes


  1. Pre-heat your oven to 180C
  2. Then, begin making your pastry:
    - Cut the 170g butter (cold, straight from the fridge) into small cubes
    - Then, add the flour, icing sugar and butter into a large mixing bowl
    -Use your hands (or a food processor) to mix together until it forms rough breadcrumb texture
    -Then, gradually add in the water (spoon by spoon) and mix until the dough comes together
  3. Once the dough has come together, set aside
  4. Lightly flour your work surface, and use a rolling pin to roll the pastry into a thin sheet which is large enough to cover your tart tin
  5. Brush the tart tin with butter, so the tart doesn't stick to it once cooked
  6. Then, layer the pastry over the tin and push in
  7. Trim around the edges of the pastry leaving just a small amount of excess hanging over the rim (see images/video above for example)
  8. Use a fork to poke some small holes into the pastry base
  9. Then, lay a sheet of parchment paper into the base of the tart, and fill with either baking beans - or dried pasta, dried rice etc. (so when you blind bake the pastry it doesn't puff up)
  10. Then, bake the pastry base in the oven for 10 minutes of 180C
  11. Remove from the oven, and remove the parchment and baking beans
  12. Now, begin making the filling (you could start this when the pastry is in to blind bake, or once it's out of the oven, whenever you feel most confident to do so).
  13. Heat the 130g golden syrup, 50g butter and 30g light brown sugar in a large saucepan until melted and combined - then turn off the heat.
  14. Add a pinch of salt, stir
  15. Then, add in the cornflakes - and stir to fully coat in the sticky mixture - this is your tart filling!
  16. Next, add the 130g jam to the cooked pie base, use a spoon to smooth it out
  17. Then, add on the cornflake mixture - use a large spoon to flatten it down and spread it out evenly
  18. Finally, place the tart back in the oven to cook for a final 5 minutes
  19. Serve and enjoy! This is delicious alone, with ice cream, or with custard
