How to Make Flapjack Recipe: A Quick Glimpse
Start by lining your baking tin and gently melting butter in a large saucepan over medium heat. Once the butter is silky and melted, remove from heat and stir in the light brown sugar, golden syrup, porridge oats, and salt until every oat is coated in that glorious buttery sweetness.
Scoop the mixture into the lined tin, pressing firmly with the back of a spoon to form an even, compact layer. Bake until the edges turn golden and irresistible, then let the flapjack cool completely to set its soft, chewy center. Lift out, slice into squares, and savor every bite!
Chewy, Golden, Perfect: Tips for Flapjack Recipe
For flapjacks with beautifully chewy edges and a soft, tender middle, keep a close eye on the bake timeโaim for golden edges but a pale center. Compacting the mixture firmly in the tin ensures they hold together once cooled.
If youโre craving a twist, drizzle with melted chocolate, scatter over dried fruits, or sprinkle in a handful of seeds for extra crunch and flavor. Porridge oats or rolled oats work bestโavoid instant or steel-cut oats to keep the texture just right.

Storing Your Flapjack Bliss
Keep leftover flapjacks in an airtight container at room temperature for up to five days, layering with parchment to prevent sticking. They freeze well tooโlayer between parchment in a container or freezer bag. Thaw at room temperature or in the fridge, ready for when a sweet, nostalgic treat calls your name.

Flapjack Recipe
Ingredients
- ยผ tsp salt
- 160 ml ยฝ cup golden syrup
- 400 g 4 cups porridge oats or rolled oats (avoid jumbo or steel-cut)
- 200 g 2 sticks unsalted butter
- 160 g ยพ packed cup light brown sugar
Instructions
- Set the oven to 160ยฐC/320ยฐF (fan). Line a square baking tin (20cm x 20cm, 5cm deep) with baking parchment, ensuring an overhang of 1โ2 cm for easy removal later. Place the butter in a large saucepan and melt gently over medium heat. Once fully melted, switch off the heat and add the sugar, golden syrup, oats, and salt directly to the pan. Combine thoroughly until the mixture is uniform. Spoon the mixture into the prepared tin, level it out with the back of a spoon, and press down firmly so it compacts well. Bake for 23โ25 minutes until the edges are golden. Allow to cool completely in the tin at room temperature for a minimum of 4 hours. Once fully cooled, lift the flapjack out using the parchment, peel it away, place on a chopping board, cut into squares, and serve.
