Mary Berry’s flapjack recipe is so easy to prepare and only takes 30 minutes to bake.
This delicious recipe for flapjacks makes 24 bars using just four store cupboard ingredients – but you could add dried fruit or a sprinkle of desiccated coconut to give them an extra twist. These soft and chewy flapjacks will keep in an airtight container at room temperature for up to two weeks. Mary Berry recommends storing her flapjacks with a slice of bread to stop the flapjack bars from drying out and losing moisture.
- 125g butter (plus extra for greasing)
- 90g golden syrup
- 90g light muscovado sugar
- 250g rolled oats
Lightly butter a roasting tin or shallow cake tin (about 20 x 30cm).
Combine the butter, syrup, and sugar in a saucepan and heat gently until the ingredients have melted and dissolved. Stir in the oats and mix well.
Spoon into the prepared tin and smooth the surface with a palette knife. Bake in a preheated oven at 180C (160C fan, Gas 4) for about 30 minutes.
Leave to cool in the tin for about 5 minutes, then mark into 24 fingers. Leave to cool completely, then cut and remove from tin.
Top tips for making Mary Berry’s flapjack recipe
It is very important that you grease the tin you plan on using. This will make sure that the flapjack mixture doesn’t get stuck in the tin once baked. Baking parchment or paper is essential. Not only will it stop the flapjacks from sticking, like greasing the tin, but it will also help you to pull them out of the tin after baking. Watch our step-by-step video guide on how to line a cake tin with baking paper. If you don’t have baking parchment just opt for greasing the tin instead or choose a loose base tray or cake tin so you can push the flapjacks out from the bottom.
How do I stop flapjacks from being too crunchy?
If you don't like your flapjacks too crunchy, we’d recommend adding self-raising flour to the mixture. A couple of tablespoons of flour will help to soften the flapjacks.
Mary Berry recommends not to boil the syrup mixture. A light simmer should do the trick but even then be careful not to overheat the butter, sugar, and syrup otherwise it will become rock hard when set making the flapjacks crunchy and dry.
What oats are best for making flapjacks?
We’d recommend using porridge oats for making Mary Berry’s flapjacks. Porridge oats tend to form together better than jumbo oats which are grainier in texture.
