  2. Combine Dry Ingredients: Transfer mixture to an electric mixer bowl, add sugar and whisk briefly to combine.
  3. Add Egg and Water: Create a well in the center, add egg and 1 tbsp cold water, mix on slow with dough hook until starting to come together. Add second tbsp water if too dry.
  4. Form Dough Ball: Shape dough into a ball with hands, handle minimally to avoid overworking.
  5. Chill Dough: Wrap dough ball in cling film and refrigerate for 30 minutes.
  6. Roll and Line Tart Tin: On a floured surface, roll dough to 0.5cm thickness, lay over a 23cm fluted tart tin, press down to line base and sides, leaving about 1-inch overhang, trim excess loosely.
  7. Chill Tart Shell: Prick base with fork, place in fridge for another 30 minutes.

  9. Blind Bake Base: Cover pastry with baking paper and baking beans, bake 15 minutes, remove beans and paper, bake 5-10 more minutes until golden.
  10. Trim Edges: While hot, trim excess pastry flush with tart rim using a sharp knife.
  11. Cool Tart Shell: Let tart base cool while preparing filling.
  12. Prepare Filling: In a large saucepan, gently heat butter, golden syrup, brown sugar, and pinch of salt over low-medium heat until melted and combined.
  13. Mix in Cornflakes: Remove pan from heat and stir in cornflakes coating them thoroughly.
  14. Spread Jam: Evenly spread raspberry jam over cooled tart base.
  15. Add Cornflake Mixture: Spoon and distribute cornflake mixture on top of jam layer.
  16. Bake Tart: Bake tart for 5-7 minutes until cornflakes are lightly toasted.

Notes

  • Use cold butter for a flakier pastry texture.
  • Rolling dough evenly ensures uniform baking.
  • Blind baking prevents a soggy bottom when adding moist filling.
  • Use baking beans or dried rice for blind baking to keep pastry shape.
  • You can substitute raspberry jam with any preferred fruit preserve.
  • Serve with warm custard for an authentic schooltime treat.
  • Store leftovers covered in the refrigerator for up to 3 days.
