If you are new to baking, or you want some easy Christmas baking, you can't go wrong with flapjacks. You just melt the butter, add the golden syrup and sugar and then stir in the oats before baking.
The hardest part is waiting for them to cool, when you just want to eat them! Little squares of this are great for a festive themed school lunch box.

Cinnamon Flapjack Ingredients

A full ingredients list, along with US Customary and Metric measurements, can be found in the recipe card at the end of this post.
- Butter - This is what gives the flapjacks a lovely creaminess. We used unsalted butter.
- Sugar - All the sweetness comes from the golden syrup and the soft brown sugar. The golden syrup helps to make it nice and sticky and the brown sugar is what gives it the lovely golden colour.
- Oats - This is the star of the flapjacks. We used rolled oats, as we find that they help the flapjacks stick together.
- Spices - We added cinnamon and ginger to give them all the festive flavours. You can adjust it to suit your own tastes though. add an extra teaspoon of cinnamon if you want a real intense cinnamon flavour.
Cinnamon Flapjack Variations
Flapjacks are so easy to adapt, which is one of the things we love about them. Use this as a base recipe and then feel free to add in all of your favourite ingredients. Although, maybe not all at the same time.
- A drizzle of chocolate on top (melted dark, milk or white all work well)
- Dried fruit (raisins, cranberries and cherries are good)
- Diced apple (this is like an apple pie flapjack).
- Nut butter (cashew is our favourite)
- Chocolate chips
- Mashed banana
How to Make Cinnamon Flapjacks
Prep: Preheat your oven to 180°C/160°C(fan)/350°F/Gas 4 and line a 27x20cm (10.5x8inch) baking tray with baking paper.

- Step 1: In a large saucepan, melt the butter over a low heat.

- Step 2: Add the sugar and golden syrup to the melted butter and once it has dissolved, remove from the heat.

- Step 3: Stir in the oats, cinnamon and ginger. Taste to see if it has enough cinnamon/ginger in it for you. If not, add more to taste. Mix well so all the oats are covered.

- Step 4: Pour the mixture into your baking tray and put in the oven for 25 minutes. The middle should still be a little soft and wobbly, but the edges will have started to turn golden brown. It will firm up as it cools.
- Step 5: Remove from the oven and allow them to cool completely. Remove from the tin and use a sharp knife to cut into slices.
Serving Suggestions
These are pretty indulgent as they are, so they really don't need anything else. But they go really well with a nice hot drink. Why not try one of the ones we have on the blog:

Dannii's Top Tips
- Try not to overheat the butter, otherwise it will split like it has in our photo. However it won't make much of a difference to the final taste and texture.
- Add a pinch of salt to intensify the flavour. However we left this out as we were making it for kids to eat.
- Make sure these are gluten free by using certified gluten free oats.
- Leave them to cool completely before cutting. This allows them to keep their shape.
- To make these vegan, simply swap the butter for your favourite dairy free alternative and then make sure that any toppings or add-ins are vegan too.
- To ensure this recipe is definitely gluten free, use gluten-free certified oats.

Frequently Asked Questions
These flapjacks will keep in an air tight container for around a week to 10 days. After that they will start to dry out. You can also freeze them, individually wrapped, and they will keep in the freezer for about a month.
Slicing them into bars while still warm can often cause them to fall apart. Instead, if you partially score them and then pop them in the fridge, this will speed up the cooling process and result in solid granola bars. Packing the mixture down firmly in the baking tin before baking also helps.
These flapjacks are sticky, soft and chewy on the inside and a nice crisp coating - just the way flapjacks should be. If you wanted your flapjacks harder and crispier, then simply bake them for 5 minutes longer.

Ruth says
My son decided to bake make flapjacks and try a different recipe. These taste absolutely delicious but they have turned out very thin, less than 1cm high and didn't fill an 18cm square tin let alone a 40x25cm tin. Are the UK metric weights correct? I would love to post a picture but this doesn't seem possible.
Dannii says
Hello! I'm really sorry, but those measurements were wrong. The tin we used 27cmx20cm - I am not sure why it says different. I have changed it now though.
Alex says
Do you think you could substitute the golden syrup for maple syrup 1:1 please?
Dannii Martin says
No, maple syrup is not sticky enough. Not only does the golden syrup add sweetness, but it helps everything stick together. You could try it with honey, but it's quite unpredictable as it's natural and you get such different consitencies.
