Easy Flapjack Recipe

This flapjack recipe makes easy flapjacks that are chewy, delicious, packed with flavor and a classic British staple.

When I first moved to the UK, people kept offering me “flapjacks” and I was very confused as flapjack is another word for pancakes in the US, and it would be something like 3 in the afternoon.

As it turns out, flapjacks in the UK are these chewy oat bars, sort of like a granola bar, but specifically made for dessert in most cases because they’re packed with brown sugar and golden syrup and all things that are not good for you (in the best way possible).

In this flapjack recipe, which are Mary Berry’s original flapjacks, you’re going to learn how to put together just 4 ingredients to make these delicacies!

History of Flapjacks

The first use of the word flapjack dates to about the 16th century, so when you eat a pan of these, you’re basically eating history in the best way possible.

However, it may not have referred to the exact kind of oat bar that we know them as today.

That appeared in the mid 1930s, and have been a staple in any Brits diet with a nice cup of tea ever since!

Must-Have Baking Tools (seriously)

What You’ll Need

You just need four ingredients for flapjacks, with exact amounts being shown in the recipe below.

They are: rolled oats, golden syrup, butter, and light brown sugar.

Now, if you’re in the US, golden syrup might not be something you can easily find on just any grocery store shelf, but you can order it from Amazon or find it in most Whole Foods or your international section of your grocery store.

Golden syrup isn’t another word for maple syrup, but we’ll talk about that more below.

How to Make Flapjacks

The thing I love about flapjacks is that you have to try really, really hard to mess them up.

There’s no messing around with 1/2 teaspoon of this and 1/2 teaspoon of that.

All you do is put a small pot on medium low heat on the stove, while melting the butter, light brown sugar, and golden syrup together.

Continuously stir until the butter is melted.

Then, pour in the oats, stir in until fully incorporated, and pour immediately into a buttered square shaped (or other shape, it’s not going to affect the taste!) pan.

For this recipe, I used an 8 inch square pan.

Put it into the oven for about 30 minutes, or until the top has gone a golden brown (but not burnt), and pull it out and let it cool completely.

Cut up your flapjacks into squares or slices, and there you go!

Extra Tips

Some people like to cut their flapjacks when completely cooled, while I like to cut mine when it’s still slightly warm as I find it easier to cut through, but either way is fine.

To get them out of the pan, I like to basically cut all of the slices into the pan, then go in with a spatula and pry one side out.

The rest will easily follow!

What Else Can I Add?

I love plain flapjacks, but you can add in any additives you can think of.

Some people like them with raisins, or you could do chocolate ones by adding chocolate chips or just melting chocolate into the mixture.

Really, your imagination is the limit.

Can You Freeze Flapjacks?


Put flapjacks in the freezer for the future, up to about 3 months.

Individually wrap them for best results.

Can I Substitute Maple Syrup for Golden Syrup?

If you only have a maple syrup instead of golden syrup, you can substitute it if you want if you’re going to be happy with the final flavor.

It won’t taste like the British counterpart, but it will do the same thing in the recipe.

You also use golden syrup in Cornish fairings, so you can make that recipe as well if you manage to find some.
