Why We Love This Recipe

There’s something magical about the recipes from our childhood, and this Cornflake Tart brings all that nostalgia flooding back. It’s one of those bakes that instantly takes you back to school dinners – that golden moment when dessert was wheeled out and you hoped it was this crunchy, sticky treat with a ladle of hot custard.

Our version brings the classic right back into the spotlight, and once the kids got a taste of this one, they were hooked. Flaky pastry, sweet strawberry jam, a golden crunchy nut cornflake topping with just the right crunch – this dessert is a winner for all ages.

Ingredients

For the Sweet Pastry:

  • 250 g plain flour
  • 125 g unsalted butter softened
  • 90 g caster sugar
  • 1 medium egg beaten

For the Filling:

  • 50 g unsalted butter
  • 125 g golden syrup
  • 25 g light brown sugar
  • 150 g Crunchy Nut Cornflakes
  • 100 g strawberry jam

Instructions

Make the Pastry

  • Rub the flour and butter together with your fingertips until the mix looks like breadcrumbs.
  • Stir in the sugar, then add the beaten egg and bring the dough together.
  • Lightly knead on a floured surface until smooth. Form into a ball, wrap in cling film, and chill in the fridge for 30 minutes.

Blind Bake the Base

  • Preheat your oven to 180°C (160°C fan).
  • Lightly grease and flour a 9” round tart tin.
  • Roll out the chilled pastry to fit the tin with a slight overhang.
  • Prick the base with a fork, then line with baking paper and fill with baking beans or rice.
  • Bake for 10 minutes, remove the paper and beans, then bake for another 5 minutes.
  • Trim the edges of the tart case to sit flush with the tin.

Prepare the Filling

  • In a saucepan, gently melt the butter, golden syrup, and brown sugar over low heat until smooth.
  • Stir in the Crunchy Nut Cornflakes until fully coated.

Assemble & Bake

  • Spread the jam evenly over the pastry base (the warmth will help it spread easily).
  • Spoon the cornflake mixture over the jam and gently press it down.
  • Bake for 5–10 minutes until the top is golden and crisp.

Cool & Serve

  • Allow the tart to cool in the tin for about 30 minutes before removing.
  • Slice and serve warm with plenty of custard – the ultimate throwback dessert!

Notes

Notes & Tips
For extra nostalgia, use raspberry jam instead of strawberry.
You can substitute regular cornflakes if preferred.
Tart can be made a day ahead and reheated in a low oven.
