The Sweet Taste of School Days – A Cornflake Tart Revival
Do you remember the days of lunch trays and sponge puddings, where dessert was the highlight of the school cafeteria? I sure do. And nothing takes me back quite like a big, wobbly slab of Cornflake Tart, drowned in creamy, warm custard. It’s one of those classic British puddings that instantly triggers a bit of nostalgia—and honestly, it still tastes just as dreamy today.
This recipe is a proper tribute to the good ol’ days: a buttery shortcrust base, a thick smear of raspberry jam, and a crunchy golden syrup cornflake topping that stays chewy in all the right places. And of course, we’re not skipping the custard. Nope, we’re making it from scratch—and trust me, it’s worth every stir.
So whether you’re whipping this up for a retro-themed dinner party or just craving a comforting dessert with a cuppa, this Classic Cornflake Tart will hit the spot.
Let’s jump right in with the pastry, because it’s the foundation of the tart and oh-so worth making from scratch.
Step 1: Make the Shortcrust Pastry
Now, I know pastry can seem intimidating, but this one’s as simple as it gets. You don’t need fancy equipment or any special techniques—just your hands and a bit of patience (and maybe a chilled glass of something nearby if it’s a warm day!).
Ingredients for the pastry:
-
125g unsalted butter (cold and cubed)
-
250g plain flour
-
Pinch of salt
-
3–4 tbsp cold water
Method:
-
Rub in the butter: In a large bowl, mix the flour and salt, then add the butter. Using your fingertips, rub the butter into the flour until it resembles breadcrumbs. It should look sandy and crumbly.
-
Bring it together: Gradually add the cold water, one tablespoon at a time, and mix gently until a dough starts to form. Be careful not to overwork it—you want it just combined.
-
Chill out: Shape the dough into a disc, wrap it in cling film, and pop it in the fridge for at least 30 minutes. This helps the butter firm up again and stops the pastry from shrinking in the oven.
Step 2: Bake the Tart Shell
Once your pastry has chilled, it’s time to roll it out and get baking.
-
Preheat your oven to 180°C (fan).
-
On a lightly floured surface, roll out your dough to fit a 20cm tart tin (about the thickness of a £1 coin).
-
Carefully press the dough into the tin, trim the edges, and prick the base with a fork.
-
Line the tart with baking paper and fill with baking beans or dried rice to blind bake for 15 minutes.
-
Remove the paper and beans, then bake for another 5 minutes, or until lightly golden.
It’s the smell for me—something about butter and flour coming together in the oven that always makes the kitchen feel like home.
Step 3: Add the Jam Layer
As soon as your tart case comes out of the oven and is still warm, spread 150g of raspberry jam all over the base. You can use strawberry if that’s what you have—it’s really about what makes you happy. I love to add a tiny squeeze of lemon juice to the jam before spreading it; it lifts the sweetness and makes everything taste a little brighter.
Now let’s talk about the real star of the show…
The Cornflake Topping & Dreamy Homemade Custard
Step 4: Make the Sticky Cornflake Topping
This part is quick but oh-so satisfying. The scent of golden syrup bubbling away with butter and sugar will make everyone hover around the kitchen.
You’ll need:
-
100g cornflakes
-
100g golden syrup
-
50g butter
-
30g light brown sugar
Method:
-
In a medium saucepan over low heat, melt together the butter, golden syrup, and sugar. Stir gently until everything is smooth and glossy.
-
Take it off the heat and fold in the cornflakes. Mix gently to coat every flake in that syrupy goodness.
-
Spoon the sticky cornflakes over the jam layer. Gently press them down with the back of a spoon to form an even layer.
Now, back into the oven it goes for 5–8 minutes—just enough to set that golden topping without losing the crunch.
At this point, the tart is looking golden, gooey, and gorgeously retro. But we’re not stopping there. Let’s make the custard, because what’s a Cornflake Tart without a big, velvety pool of the stuff?
Step 5: Homemade Custard (Yes, It’s Worth It)
There’s nothing wrong with using store-bought custard in a pinch, but if you’ve got 10 minutes, homemade custard is next-level. Rich, smooth, and flecked with vanilla—it’s the kind of sauce you’ll want to drink straight from the jug.
You’ll need:
-
4 egg yolks
-
500ml whole milk
-
1 tsp vanilla extract
-
2 tbsp caster sugar
-
1 tbsp cornflour (optional, for a thicker custard)
Method:
-
In a bowl, whisk the egg yolks with sugar and cornflour until smooth.
-
In a saucepan, gently heat the milk and vanilla until it’s just about to boil.
-
Slowly pour the hot milk into the egg mixture, whisking constantly so the eggs don’t scramble.
-
Pour the custard mix back into the saucepan and heat gently, stirring constantly until it thickens to your desired consistency.
Don’t rush this—low and slow is key. Once it’s ready, you’ll be left with a glossy, warm custard that’s just begging to be poured over that golden tart.
FAQ & Final Thoughts on the Classic Cornflake Tart
FAQ: Your Questions Answered
1. Can I use store-bought pastry?
Absolutely! Ready-made shortcrust is a great shortcut. Just make sure to blind bake it as described for the best texture.
2. Can I make the tart ahead of time?
Yes! It keeps beautifully for up to 3 days in an airtight container. It’s great cold too.
3. Can I freeze Cornflake Tart?
You can freeze the baked tart without the custard. Wrap tightly and freeze for up to 2 months. Reheat gently in the oven before serving.
4. What can I use instead of golden syrup?
Honey or light corn syrup can work in a pinch, but golden syrup gives that signature flavor and chew.
5. Is the custard necessary?
Technically no, but emotionally? Yes. The tart is lovely on its own, but custard turns it into a proper pudding.
6. Can I make this gluten-free?
Yes—use a gluten-free shortcrust pastry and ensure your cornflakes are gluten-free (many are, but double-check the label).
7. Can I use other types of jam?
Definitely! Strawberry, apricot, or even plum jam would be delicious. Just aim for one that’s not too runny.
