Description

This buttery flapjack recipe combines golden syrup, oats, and sweetened condensed milk for a chewy, gooey treat perfect for snacks or tea time.


Ingredients

Scale
  • 125 g butter (unsalted or salted)
  • 75 g golden syrup
  • 75 g Demerara sugar
  • 100 g sweetened condensed milk
  • 250 g porridge oats

Instructions

  1. Preheat your oven to 350°F (180°C). Grease and line an 8-inch square baking tin with parchment paper.
  2. In a saucepan, melt the butter, golden syrup, and Demerara sugar over low heat until smooth and fully combined.
  3. Stir in the sweetened condensed milk and mix until creamy.
  4. Remove the pan from heat and stir in the porridge oats, ensuring they’re evenly coated.
  5. Press the mixture firmly into the prepared tin, leveling it with the back of a spoon.
  6. Bake for 20–25 minutes or until the edges are golden.
  7. Allow the flapjacks to cool completely in the tin before slicing into squares or rectangles.

Notes

  • Use gluten-free oats for a gluten-free version.
  • Substitute honey for golden syrup if unavailable.
  • Cool completely before cutting to avoid crumbling.
