Easy Flapjack Recipe – Chewy and Buttery

Easy flapjack recipe – I mean, it has just four ingredients, so it really is super easy to make these flapjacks.

First off, flapjacks are not pancakes! The internet seems confused about this. You make flapjacks with oats, not an eggy batter. They are oat bars or oat squares. Read this post if you are looking for a great pancake recipe.

This is more of a chewy flapjack recipe with a lovely buttery flavour. If you want a crispy flapjack recipe, just use a shallower cooking tin and bake at a higher temperature.

Are Flapjacks Made With Honey or Golden Syrup?

Flapjacks can be made using honey or golden syrup. You just substitute one for the other and you do not need to adjust the quantities.

What Oats Are Used To Make Flapjacks?

You can make this easy flapjack recipe with any type of oats but I find the smaller the oats the better the flapjacks taste. The jumbo oats make great flapjacks but I just like the smaller, regular porridge oats.

Fruit, Nut, Chocolate Flapjacks

Turn this into an easy chocolate flapjack recipe by adding chocolate on top. Simples. You can also melt chocolate and pour it on top of the flapjacks when they have cooled.

In fact, you can add dried fruit, nuts and coconut into these flapjacks and make them any way you like.

Easy Flapjack Recipe – Just Four Ingredients

I like to keep my flapjacks simple. I use really cheap oats, butter, brown sugar and honey or golden syrup (depending on what I have in the kitchen). Those are the four ingredients for your basic flapjack recipe.

Then, I top with shards of chocolate and sprinkle liberally with sea salt. And that’s it.

Flapjacks Are Quick to Make

You can melt everything together in around five minutes if all your ingredients are at room temperature. Then, it is just a quick 30 minutes in the oven. It is an agonisingly long time to wait until they cool though. OK, who am I kidding? I never wait until they have cooled.

So, without further delay, here is my easy flapjack recipe.


225 grams of butter

250 grams of brown sugar

80 grams of honey or golden syrup

350 grams of oats

Chocolate, optional

Sea salt flakes, optional (but highly recommended)

Easy flapjack recipe by Melanie May.


Preheat the oven to 150°C / 130°C fan assisted / 300°F / gas mark 2.

Grease and line a rectangular cake tin (roughly 20cm x 30cm) or a round pie dish. The deeper the dish, the chewier the flapjack. I love deep dish flapjacks.

In a large saucepan, over medium heat, melt the butter, sugar and honey or golden syrup, whichever you are using.

If you are using dried fruit, nuts or coconut, mix them through the dry oats.

Add the oats to the saucepan with the melted butter, sugar and honey or golden syrup

Stir until completely combined and all the oats are coated.

Pour the mixture onto the lined and greased tin.

Using the back of a spoon, palette knife or spatula, smooth the mixture out to the edges.

Press down lightly on the mixture with the back of a spoon, palette knife or spatula.

Add chocolate pieces on top and sprinkle with sea salt flakes.

Put into the preheated oven and bake for 30-35 minutes until a deep golden colour.

Take out of the oven and leave to cool in the tray for about 20 minutes before transferring onto a wire rack to cool completely.

If you cut them when they are warm, they will fall apart, however, even when they fall apart they are delicious.

I’ll be honest with you, I have no idea how many flapjacks this recipe makes. It all depends on how big or small you cut them. We just cut huge slices and pig out.

When they are completely cold, store in an airtight container and keep somewhere cool and dark, but not in the fridge.

Flapjacks will keep for about two weeks if you keep them in an airtight container. If you can make a batch of these last two weeks, you have way more willpower than me.
