🧾 Ingredients & Why They Matter
🥧 For the Shortcrust Pastry (or use pre-made):
- 1¼ cups (160g) plain/all-purpose flour
→ The base structure of your tart. Plain flour gives a tender crust. - ½ cup (115g) cold unsalted butter, cubed
→ Fat for flakiness. Cold butter is key to creating those crumbly layers. - 2–3 tbsp cold water
→ Just enough to bring the dough together. - Pinch of salt
→ Enhances flavor subtly.
✅ Shortcut: You can use 1 sheet of ready-rolled shortcrust pastry if you want to skip this step.
🍓 For the Filling:
- 5 tbsp (about 150g) strawberry or raspberry jam
→ A sweet, tangy layer that pairs perfectly with the crunch. - 2 tbsp (30g) unsalted butter
→ Melts into the syrup for coating cornflakes. - 2 tbsp (30g) light brown sugar
→ Adds richness and a toffee flavor. - 2 tbsp golden syrup
→ Traditional UK ingredient that gives chewiness and shine (can substitute with honey or light corn syrup). - 2½ cups (60g) cornflakes
→ The hero ingredient. Provides crunch and visual appeal.
🍽️ Equipment Needed
- 8–9 inch tart tin (loose-bottomed preferred)
- Rolling pin (if using homemade pastry)
- Baking paper & baking beans/rice (for blind baking)
- Saucepan
- Spatula or wooden spoon
🥣 Step-by-Step Instructions
1️⃣ Make the Shortcrust Pastry (if not using store-bought)
- Rub butter into flour:
In a large bowl, add flour and a pinch of salt. Add cold, cubed butter. Using your fingertips, rub the butter into the flour until it resembles breadcrumbs. - Add water:
Drizzle in cold water, one tablespoon at a time. Mix with a fork or your hands until it forms a dough. - Chill the dough:
Form into a disk, wrap in cling film, and chill in the fridge for 30 minutes. This relaxes the gluten and prevents shrinkage.
2️⃣ Roll and Bake the Pastry Base
- Roll out the dough:
On a lightly floured surface, roll out your chilled pastry to about ⅛ inch (3mm) thickness. - Line the tart tin:
Carefully transfer the pastry to your tart tin, pressing into the edges. Trim the excess but leave a small overhang. - Dock the base:
Prick the base with a fork to prevent air bubbles. - Blind bake:
Place parchment paper over the pastry and fill with baking beans or rice. Bake at 375°F (190°C) for 15 minutes. - Remove weights & bake again:
Take out the weights and bake for another 5–7 minutes, until the crust is lightly golden and dry. - Cool slightly:
Remove from oven and let cool for 5 minutes.
3️⃣ Prepare the Cornflake Topping
- Melt syrup mixture:
In a saucepan over low heat, melt the butter, brown sugar, and golden syrup together. Stir until smooth and bubbling. - Coat the cornflakes:
Remove from heat and add cornflakes. Gently stir until evenly coated. Be careful not to crush them too much — you want some large flakes for texture.
4️⃣ Assemble the Tart
- Spread jam layer:
Spoon the jam evenly over the base of the pre-baked pastry. Use the back of a spoon to spread it smoothly. - Top with cornflake mixture:
Spoon the coated cornflakes over the jam, pressing down slightly to form an even layer but without compacting too much (retain that crunch!).
5️⃣ Final Bake
- Return the assembled tart to the oven.
- Bake for 7–10 minutes at 375°F (190°C) — just enough to set and toast the top layer slightly.
✅ Tip: Keep an eye on it — you want golden, not burnt, flakes.
6️⃣ Cool & Serve
- Let the tart cool for 10–15 minutes in the tin.
- Carefully remove from the tart pan.
- Slice and serve warm or at room temperature.
🍮 Best Ways to Serve
- With warm custard (classic British style!)
- A dollop of whipped cream
- A scoop of vanilla ice cream
- A dusting of powdered sugar (optional)

🧊 Storage Tips
- Store leftovers in an airtight container at room temperature for up to 3 days.
- Reheat slices in the oven or microwave if desired.
🔁 Variations
- Different jam flavors: Try apricot, blackberry, or cherry.
- Nutty version: Add finely chopped almonds or pistachios to the cornflake mixture.
- Chocolate drizzle: Add melted dark or milk chocolate over the top once baked and cooled.
