Place the butter, caster sugar, golden syrup and condensed milk into a saucepan.

Melt the ingredients together on a medium-low heat so they soften and melt gradually. Keep stirring so they don’t burn.

Remove the saucepan from the heat and stir in the oats.

Pour 50%-75% of the flapjack mix into the prepared cake tin and level off.

Spoon on good amounts of jam. These were heaped tablespoons.

Spread the jam all over the flapjacks.

Place the last few spoonfuls of the flapjack on top.

Gently level out and it’s oven ready.

Put the flapjacks in the oven and bake for 20 minutes until golden brown.
When they are baked and still warm, gently slice the flapjacks. It’s a lot easier when they are still warm.

Jam flapjacks FAQS
Why do my flapjacks always fall apart?
Flapjacks often fall apart due to improper ratios of ingredients or baking techniques. Key issues include insufficient binding agents like golden syrup or butter, causing the oats to not stick together well.
Over baking can also dry them out, making them crumbly. Conversely, underbaking leaves them too soft to hold their shape. Ensuring the mixture is well-combined and compacted firmly in the baking tray can help.
Should flapjacks be soft when they come out of the oven?
Yes, flapjacks should be soft when they come out of the oven. They will firm up as they cool. Over baking can make them too hard and dry. It’s important to let them cool completely in the tin before cutting to ensure they hold their shape and achieve the desired chewy texture.
Are rolled oats and porridge oats the same?
No, rolled oats and porridge oats are not the same. Rolled oats are whole oats that have been steamed and flattened. Porridge oats, often called instant oats, are finer as they are cut into smaller pieces and more processed. This makes porridge oats quicker to cook, but they result in a creamier texture compared to the chewier texture of rolled oats.
Is flapjack a UK thing?
Yes, flapjack is primarily a British treat. It typically consists of oats, butter, and golden syrup, baked until crisp. While similar oat-based bars exist in other countries, the British flapjack is distinct in its simplicity and chewy texture. In the US, “flapjack” refers to a pancake, adding to the confusion.
