What Is a Flapjack?
Traditional British Treat
In the UK, a flapjack refers to a sweet, baked oat bar made primarily with oats, butter, sugar, and golden syrup. It differs from the American version of a flapjack, which refers to a pancake. British flapjacks are more like granola bars dense, chewy, and buttery, often baked until golden brown.
Flapjack Variations
Though the base ingredients remain consistent, flapjacks can be adapted to suit different preferences. Some people like to add dried fruits, nuts, chocolate chips, or seeds to the mixture. Others prefer theirs soft and chewy, while some go for a crispier edge. The beauty of the classic flapjack recipe is its flexibility it’s easy to personalise with minimal effort.
Quick Flapjack Recipe (UK Version)
Ingredients
Here is a basic quick flapjack recipe using ingredients commonly found in UK households. This version yields approximately 12 bars.
- 225g porridge oats
- 125g unsalted butter (plus extra for greasing)
- 125g light brown sugar
- 2-3 tbsp golden syrup
- Optional: pinch of salt or a dash of vanilla extract
Equipment
- 20cm x 20cm (8-inch) square baking tin
- Medium saucepan
- Wooden spoon or spatula
- Baking parchment
Instructions
- Preheat your oven to 180°C (160°C fan) or gas mark 4.
- Line your baking tin with parchment paper and lightly grease it with butter.
- In a saucepan, melt the butter over a low heat. Add the brown sugar and golden syrup, stirring continuously until smooth and fully combined.
- Remove the saucepan from the heat and stir in the oats. Make sure all the oats are coated evenly in the buttery syrup mixture.
- Pour the oat mixture into the prepared tin, pressing it down firmly and smoothing the surface with a spatula or the back of a spoon.
- Bake in the oven for 20-25 minutes until golden brown around the edges. For a chewier flapjack, bake closer to 20 minutes. For a crispier texture, leave it in for the full 25 minutes.
- Remove from the oven and allow to cool in the tin for 10-15 minutes before slicing into squares or bars. Leave to cool completely before removing from the tin to avoid crumbling.
Tips for Perfect Flapjacks
Don’t Overbake
One of the biggest mistakes when making flapjacks is overbaking them. They may look soft when first out of the oven, but they firm up as they cool. Overbaking leads to hard and brittle bars rather than soft and chewy ones.
Pack It Firmly
When pressing the mixture into the baking tin, apply firm pressure with a spatula or spoon. This helps the flapjack hold together well once baked and cooled. Gaps in the mixture can result in crumbly edges or uneven bars.
Use Good-Quality Golden Syrup
The rich, buttery sweetness of golden syrup is central to the flavour of traditional flapjacks. While there are many brands available, opting for a classic UK brand like Lyle’s ensures that authentic taste.
Customising Your Flapjack
Fruit and Nut Additions
You can personalise your flapjack recipe with different mix-ins. Try these for a twist on the classic:
- 100g chopped dried apricots or dates
- 50g raisins or sultanas
- 50g chopped walnuts, pecans, or almonds
- 2 tbsp sunflower or pumpkin seeds
Chocolate Lovers’ Flapjack
To add a chocolate twist, stir in 100g chocolate chips just before pressing the mixture into the tin. Alternatively, drizzle melted chocolate over the top of the cooled bars for a more decadent finish.
Healthier Alternatives
For a slightly healthier option, you can reduce the sugar or substitute it with honey or maple syrup. Adding mashed bananas or grated apple to the mix can also add natural sweetness and moisture while cutting down on fat or sugar.
Storing and Serving
Storage Tips
Once cooled, store flapjacks in an airtight container at room temperature. They’ll stay fresh for up to a week. If stacking them, place a piece of baking paper between layers to prevent sticking.
Freezing Flapjacks
Flapjacks also freeze well. Cut them into individual bars, wrap each piece in cling film, and place them in a freezer bag. They can be frozen for up to 2 months and thawed at room temperature whenever needed.
Best Times to Enjoy
These oat bars are wonderfully versatile. You can enjoy them as:
- A mid-morning snack with a cup of tea
- A lunchbox treat for school or work
- A post-exercise energy boost
- A simple dessert with a scoop of vanilla ice cream
