Peanut Butter Flapjacks made with fine oats, golden syrup, brown sugar and butter, a delicious British treat that is rich, chewy, and so delicious! A great snack for all ages, these oat squares or oat bars are the best homemade cereal treats to have at any time of the day.
Flapjacks must be one of the most popular British treats that are easily available and even easier to make at home with just a few ingredients. The addition of peanut butter might not be traditional, but it adds so much flavour and richness.
While a flapjack is a baked oat bar in the United Kingdom and might have different names in other English-speaking countries, in the USA the term flapjack usually refers to a pancake.
If you are a peanut butter fan, then these bites are definitely for you! They do have quite a large amount of sugar added, but that is crucial in order to achieve the chewy texture we love.
The dark brown sugar adds to the richness of the flapjacks, while also adding a depth of colour, and together with the peanut butter make a treat that is well loved by absolutely everyone in the family.
Given the amount of butter and refined sugar added, I wouldn't quite call them too healthy, but if you are after a more wholesome snack, how about my Banana Oat Cookies?
- oats - I used fine porridge oats rather than jumbo oats
- butter - the salted butter adds a nice touch to the sweetness of the squares
- golden syrup - can be replaced with honey if golden syrup isn't easily available
- dark brown sugar
- peanut butter - I used smooth peanut butter
Step-by-step photos and instructions
- In a pan set over a medium heat, add the butter, sugar and golden syrup and use a silicone spatula to stir gently until it's all melted into a smooth paste
- Add the peanut butter, and stir again
- In a mixing bowl, add the oats together with the peanut butter mixture, and mix everything well until combined
- Line a square tin with non-stick paper, and spread the mixture, pressing down well for an even bake
- Bake in the preheated oven at 180 degrees Celsius (350 Fahrenheit) for 18-20 minutes
- Remove from the oven and cut into squares, then leave it to cool down completely
The ration butter to sugar and golden syrup is crucial in order to achieve a nice chewy texture that does not come apart - too little butter, and they will be too crumbly, not enough sugar, and they will be too tough.
Do make sure to slice the flapjacks as soon as they come out of the oven, otherwise it is impossible to do it once they cool down completely and harden.
The squares can be stored into an airtight container, and they can stay fresh for many days - best served with a nice cuppa!
