What are Flapjacks?
It really depends where you are located in the world as to what you may consider a traditional flapjack recipe! American pancakes are also called flapjacks. In Britain, though, a flapjack is an oat bar that can either be thick and chewy or thin and crispy.
An oat bar in the UK is often made with butter, oats and Golden syrup. Golden syrup is a popular British baking ingredient which you may be familiar with if you love the show The Great British Bake Off. They can easily be made at home but can also be bought at many bakeries across England.
Whether the British style oat bar is plain or flavored, it always is baked in a large, flat rectangle then cut into smaller bar sized pieces.
Flapjacks Recipe Ingredients
- Butter: You will need unsalted butter. If using salted butter, reduce added salt.
- Light brown sugar: Adds to the caramel taste of the British flapjack.
- Maple syrup: You can also use Golden syrup, honey or dark corn syrup.
- Oats: You will need porridge oats or quick cooking oats. Instant oats are not the same, so check the labeling!
- Salt: Just a pinch to enhance taste in this baked bar.
How to Make Easy British Flapjacks
Melt butter and sugar mixture together: In a medium pot add the butter, sugar and maple syrup. Over low heat, melt the ingredients until fluid and no butter is visible.
Add oats: Add quick oats and salt and mix everything together until it forms a sticky mixture.
Spread in prepared pan: Transfer the mixture into the prepared 8 inch square baking pan lined with parchment paper and spread it out evenly with a spatula.
Bake British flapjacks: Bake at 350°F for 20-25 minutes or until golden brown. Remove the pan from the oven and cool completely on a wire rack. When the flapjacks have completely cooled, remove them from the square tin and cut into desired size.
Variations
While this recipe for British flapjacks is great as is, feel free to customize it to your tastes with ingredients you have on hand or additional mix-ins!
- Other syrup: Instead of maple syrup you can use Golden syrup, honey or dark corn syrup.
- Coconut oil: Replace the butter with coconut oil for a dairy free alternative.
- Peanut butter flapjacks: Replace ½ of the butter with peanut butter.

Expert Tips
- Parchment paper lined pan: To easily remove your flapjacks from the pan, line the pan with baking paper.
- Low heat: To avoid a taffy-like sugar mixture that is hard to mix in with your oats, melt butter and sugar over low heat.
- Greasy flapjacks: Mix the butter and sugar mixture until you see no sign of melted butter to avoid greasy flapjacks
- Avoid overbaking: Remove your British oats bars when the edges are golden. Overcooking will result in a hard, crunchy flapjack.
- Crisp flapjack: Use a shallow larger sized baking pan and bake at a higher temperature.
- For cake-like fluffy and chewy flapjacks: Skip the stovetop, add all ingredients to a food processor, blend and then spread mixture in a pan and bake oat bars as directed.

FAQs
What kind of oats do I need?
Depending on where you are located in the world oats can be labeled very differently! If you are in the UK, you will need porridge oats. Elsewhere, they may be labeled quick cooking rolled oats. Do not use instant oats, though! Instant oats are rolled thinner and will bake too fast as well as they are a different texture. If old fashioned rolled oats are all you have, you might be able to use them but will need to decrease the amount to around 2 cups and increase the syrup by two tablespoons.
Are British flapjack bars chewy or crunchy?
It really depends on your preference for a chewy texture or crispier flapjack bar! For a chewier consistency, use a smaller pan to increase their thickness. For a crunchy texture, use a larger pan to spread them thinner or bake them a bit longer. I have done both ways and prefer them baked in an 8 inch pan.
Should I use Golden syrup?
You certainly can and true fans know this makes the best flapjacks! Golden syrup is a common ingredient used in British baking and is a deep amber color with a distinct caramelized buttery flavor. Replace the maple syrup with equal amounts of golden syrup.
What is the difference between classic British flapjacks and American flapjacks?
Flapjacks as called in the United States are thin pancakes that are grilled. In the UK, British flapjacks are referred to as traybakes as they are baked in a rectangular pan. You may also hear them called baked British style oat bars, British flapjack bars or golden oat bars.
