🛒 Ingredient notes
Only a small handful of pantry staples are needed to make this easy flapjack recipe (not to be confused with American flapjacks, which are actually pancakes!).
Golden Syrup - or swap for runny honey.
Butter - unsalted butter is best.
Sugar - I like to use a combination of light brown sugar and crunchy demerara sugar for the best soft texture.
Vanilla Extract - use a good quality extract and not essence for extra flavour.
Porridge Oats (rolled oats) - don't use jumbo oats as they don't absorb the melted butter mixture very well. Quick cook oats (instant oats) can also be used but the texture will be very soft.
🔪 How to make this quick and easy flapjack recipe
The recipe card with ingredient quantities and detailed instructions can be found at the bottom of the post
One: In a large saucepan melt together the butter, golden syrup, and sugars over a low heat.
Two: Take the pan off the heat and stir in the vanilla extract and oats.
Three: Press the mixture into a greased and lined 20cm square (8 inch) baking tin.
Four: Bake for 22-25 minutes until golden on top.
💡 Pro Tip - the flapjack will still look soft when you take it out of the oven. It will firm up on cooling, so don't be tempted to put the tin back in the oven like my Nana used to! Invariably we would end up with something called a tarmac cake (which you could break your teeth on!), instead of a soft squidgy flapjack!
Five: Immediately score the top of the flapjacks with a sharp knife, then leave them to cool in the tin for at least 1 hour (I often leave them overnight) before cutting them into bars.
Top Tips
- Grease and line your baking tin with nonstick baking paper (parchment) to ensure the flapjacks don't stick to the sides of the tin.
- Use a large non-stick heavy-based saucepan to melt the butter, brown sugars, and syrup together. It must be large enough to mix the oats in too.
- Firmly pack down the flapjack mixture into the tin to ensure the bars stick together and don't crumble when cut.
- Leave the flapjacks to cool completely in the tin before cutting them into bars.
- Pop the tin in the fridge to speed up the cooling process.
🍴 Serving suggestions
These easy flapjacks are perfect for a post-work-out energy boost, a quick grab-and-go breakfast, or an after-school snack for the kids.
I also serve them for afternoon tea, alongside other classic bakes such as cherry scones, fruit scones, and chocolate tiffin.
📖 Variations
- Add in 50g of chopped pecan nuts for pecan flapjacks.
- Drizzle the top of the flapjacks with dark chocolate or white chocolate and sprinkle with sea salt for extra decadence.
- Mix in dried fruit such as raisins and chopped apricots for a fruitier flavour.
- Add in chopped dates for sticky date flapjacks.
- Swap the butter for peanut butter and make vegan peanut butter flapjacks.
- Swap the golden syrup for honey.
🥡 Storage
Store - The flapjacks can be kept in an airtight container for up to a week.
Freeze - Freeze the flapjacks for up to 3 months. Defrost at room temperature before serving.
❓ Frequently asked questions
Yes! Place the flapjacks in layers (separated with baking paper) in a freezer-safe container and freeze for up to 3 months. Defrost at room temperature before serving.
Use ordinary rolled porridge oats (not jumbo oats) and allow them to cool completely before cutting the flapjack into bars.
Flapjack should be soft when you first take it out of the oven. It will set once cooled into the perfect chewy texture.
If you are unable to get hold of golden syrup then you can substitute it with runny honey, corn syrup, or maple syrup. The taste won't be quite the same though!
Flapjacks contain high levels of sugar and butter, meaning they should be enjoyed in moderation as a treat.
