British Flapjack Flavour Notes

With a first look at this Starbucks oat bar recipe (flapjacks), you may think it is similar to a Nature Valley granola bar, but that is not the case. These are wonderful little treats! The texture is somewhere between a chewy granola bar and a crispy, chewy oatmeal cookie. It is chewy and dense with slightly crispy edges.

The sugar and butter caramelize and have such a rich deep flavor – very buttery, and carmel-y which is the perfect accent to the nuttiness of the oats. You will love the dash of salt and the cinnamon. They both are very much just a hint, but they make everything else really pop. The turbinado sugar adds just tiny bursts of sweetness and very light crunch.

Starbucks Oat Bar Ingredients

British flapjacks and this Starbucks oatmeal bar are a traditional sweet treat made with simple and delicious ingredients and this recipe variation to make these Starbucks oat bars can also say the same. You will need quick cooking rolled oats, butter, turbinado sugar, brown sugar, salt, cinnamon and golden syrup which gives it that yummy chewy texture.

What is Turbinado Sugar?

Turbinado sugar is made from sugar cane juice and is also known as raw sugar. You will find that turbinado sugar has a slightly coarser texture than white granulated sugar and it has a subtle, natural molasses flavour. It is often used as a sweetener in baking and cooking, as a topping for oatmeal, cereals, and fruits, and as a sweetener in coffee and tea. In this Starbucks oat bar recipe, if you don’t have turbinado sugar, you can substitute in more brown sugar.

What is Golden Syrup?

Golden syrup is a type of inverted sugar syrup that is commonly used in British baking. It has a unique, rich flavor that is distinct from regular syrup. Golden syrup is a key ingredient in these oat bars as it helps to bind the oats together and gives the finished product a characteristic golden colour and a delicious, sweet taste.

It is a nice thick syrup similar in texture to honey. A lot of people liken it to corn syrup but it’s very different. It’s much more like honey or maple syrup. It is sweet with hints of delicious caramel. You can purchase it online or at specialty markets. You can actually even make golden syrup at home. If you can’t find golden syrup, you can use dark corn syrup or honey in its place.

Oats Used in Oat Bars or Flapjacks

Similar to flapjacks, this Starbucks granola bar recipe uses quick cooking rolled oats. There are so many different kind of porridge oats, but it is important for this recipe to use the correct one. These quick oats are thinner and smaller than regular oats, which allows them to cook more quickly and evenly. These are the oats I used in this recipe and there is also a gluten free oats (here) version to consider. You will want to make sure you are using the correct oats, but in a pinch, you could put regular oats in a food processor and pulse it 2 to 3 times to break them down.

Tips for Making the Bars at Home

  • Line the baking dish with parchment paper and allow it to hang over the sides for best results. The bars will slide right off, which makes it so easy to remove to cool and slice.
  • The key to making traditional flapjacks bars that are crispy on the outside and chewy on the inside is not to overcook them. Keep an eye on them while they are in the oven and remove them as soon as they are golden brown.
  • Make sure to mix the ingredients well, to make sure the oats will be evenly coated.
  • Once the mixture is ready press it into the baking tray, making sure it is evenly spread out and pressed firmly.
  • Use a shorter cooking time for more chewy flapjacks and a bit longer time if you prefer them crisper.

Starbucks Oat Bars FAQs

Can I add any other ingredients to the recipe?

Yes, you can add a variety of ingredients such as nuts, seeds, dried fruits, chocolate chips or even spices to the recipe to customize it to your own taste. Make sure to add them after the butter, sugar and syrup have been melted and mixed together before adding the oats.

Can I make these oat bars gluten free?

Yes, just substitute the regular quick cooking rolled oats with gluten free quick cooking rolled oats. I like to use these gluten free oats found here. Gluten free oats may not have the same texture as regular oats, so the result may be slightly different in texture and taste.

Can you make these copycat Starbucks oat bars vegan?

These oat bars contain butter, so they are not vegan. However, I have made them with plant based butter and they work fine.

What can I use in place of golden syrup?

If you can’t find golden syrup, you can use dark corn syrup or honey in its place.

How long will these Starbucks oat bars last?

The bars will last for about a week when stored in an airtight container at room temperature. They can also be stored in the refrigerator to extend their shelf life. To reheat them, you can put them in the oven or microwave for a few seconds before serving, to regain their crispiness.

Can you freeze British flapjacks?

Yes, you can freeze flapjacks. After baking and cutting into squares, place them on a baking sheet and freeze for 1 to 2 hours. Then transfer the oat bars into an airtight container or a freezer bag. They will last for up to 3 months in the freezer.

  1. These do seem to taste very similar to the starbucks ones, which i love, but my first attempt seems that they just fall apart. i didn’t get it to come out in one piece so i could cut it, very crumbly. have you maybe had this happen on your early attempts and might know what to adjust? Thanks.

    • This hasn’t happened. I do press them down firmly…maybe you need to press them down to compact them more?

      • hmm, okay, i thought i did with the spatula as i was spreading it out. will try differently next time. the taste is good though so i’ll try again sometime.

    Taste different, perhaps my version was wrong. Tasted like there was less sugar, IDK? A bit on the dry side as well. I think Starbucks uses a sugar glaze on theirs as well; “Whole Oats”.

    I made these and followed your directions to the letter. Mine were very dry and I had to cook them longer because they were not drowning up like Starbucks . When I tasted one it was very gross tasted like I was eating raw oats the inside looked nothing like Starbucks either. Most comments below were submitted by people saying they looked yummy or they looked easy to make but very few made them and then commented. Any suggestions ?

    • Oh no! I am not sure what to suggest. I have made them several times and not had what you described. Maybe you made them too thick? Did you press them down super hard? I literally use every bit of strength I have to compress them.

    Great recipe, however I think credit should be given to the company who supplied Starbucks with the oatbars until they decided to make their own copy of the original. Cakes etc. In Victoria, BC was the supplier for Starbucks until the coffee company decided to make their own (inferior) version. Its frustrating to see a corporate giant take credit for someone else’s work.

    Hi, just wondering if I could substitute honey for the corn syrup?

    I have used this recipe twice with great results. I made the following changes: substituted maple syrup instead of corn syrup; used honey instead of sugar; added whipping cream instead of milk; added half a cup (maybe more) of dried cranberries; added a handful of raw pumpkin seeds and a good handful of flax seeds; I also added a large pinch of flake salt to the dry ingredients (they were made as nutrition bars for cycling so the salt was added as an electrolyte). I found that they needed 10 mins more baking time in my oven. They are delicious.

    These were really yummy – but I got there the hard way. I was probably a little generous with the butter. So I added more brown sugar and corn syrup. Once mixed with the oats, I decided to add mini chocolate chips. But my chips kept disappearing. Then I realized that the mixture was too hot and my mini chips had melted! My mixture was now chocolate oats!! All good – I put it in a pan prepped with cooking spray and a parchment lifting sleeve. I tried pressing it down, but my mixture was too wet. At this point, I should have taken it out and added more oats for the extra liquid. But, I just threw it in the oven at CONVECT BAKE 325 for 20 minutes. I wasn’t sure if these would turn out (given my modifications) – so I mixed up some muffins too and put those in for Convection 385. I pressed down on the bars some more (after 20 minutes of baking it had dried out and I was able to finally press it). I put them back in the oven with the muffins at the higher temp for 10 minutes. I took them out, gave them a good press, and let them cool. Anyone who is not getting good results, has either made too much butter mixture (by not measuring properly), has not added enough oats, or has not allowed these to cool. I will make again next time making sure the mixture cools before adding the chocolate chips and making sure if the mixture is too wet, that I add more oats. Thanks for the recipe!

    • Glad you figured it out! I think the type/brand of oats can make a difference in the consistency and cooking time.

    Made ’em! Loved ’em! I used what I had – steel cut oats, 1/4 cup maple syrup and 1/4 cup brown sugar. I found them a tad dry and wonder if adding some oil would make them chewier. I believe that with some practice, this is a highly adaptable recipe. Thanks for putting a delicious end to my Starbucks craving!!

    My hubby and I love Starbucks oat bars but not so much the kings ransom to purchase them. This recipe is the antedote and couldn’t be easier to make! I followed everything to a ‘T’, cooked them for 20 minutes, cooled them liberally in the pan, and got picture perfect results. My husband said the word ‘love’ more than a half dozen times while eating them, all directed to the oat bars! For optimal results, I recommend following the suggestion to flatten the bars with a metal spatula just before baking (I sprayed mine with non-stick cooking spray).
