Making Jam flapjacks Top Tips

Slice your flapjacks while they’re still warm, this makes it much easier to portion them. Once they’ve cooled your flapjacks will harden and this can make slicing them very difficult.

Try warming up these flapjacks in the microwave before you serve them. It softens them up and it lets ice cream you inevitably serve it with melt.

Flapjacks are best when served warm from the oven. They do keep well in an airtight container in the cupboard for a few days. You can even reheat them in the microwave when you’re ready.

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.
