These homemade Granola Bars are deliciously chewy AND crunchy. They’re also easy to make in about half an hour and they’re filled with oats, fruit and seeds, making them the perfect after school snack or breakfast on the go.

Lots of just-baked granola bars on a wire rack, ready to eat.

I love having a batch of Granola Bars ready for peckish children after school, or when snacks are needed for packed lunches, or just to enjoy with a cuppa during a break myself!

Not only are they really easy to make and delicious, they’re also WAY better than processed, expensive pre-packaged snacks. 

The texture is just right and there’s a lovely hint of cinnamon that elevates the whole flavour.

You can also whip these up in about half an hour with very little faff or fanfare. Just solid, simple, healthy treats for everyone!

How we came up with this recipe

I first published this recipe for Granola Cereal Bars in 2014 (oh my!) and George and Harriet were only 2.

These soon became a regular in the house, especially when they started school and I needed a healthy, homemade alternative to sweet and shop-bought snacks when they were ravenous at 3.30pm.

I made sure I kept this recipe simple so I could make them quickly and easily, and I could also get them involved with a little bit of baking too. 

Along the way I discovered a few tips and tricks to make sure this recipe is just right, so follow my foolproof Granola Bar recipe below for chewy, crunchy, healthy deliciousness.


Granola Bar Ingredients Notes

The ingredients for homemade granola bars laid out in small bowls on a white counter top.
  • Butter – Use unsalted for this if you can
  • Porridge oats – See notes below for more on oats. Basically I use a combination of types but you don’t have to
  • Mixed seeds – Use whichever combination you like or have in 
  • Honey – Use whichever kind you like for this
  • Light brown sugar – This gives a nice light caramely flavour
  • Dried fruit – This can be the combination of your choice. You can also chop this to your desired chunk-size
  • Ground cinnamon – I think this really adds a little something comforting and delicious. You can leave it out if you prefer but it’s a worthy addition

How to make Granola Bars

A pan filled with melted butter, honey and sugar with a wooden spoon to mix, for step 1 in the recipe for Granola Bars.

1. Warm the butter, honey and sugar gently in a saucepan, making sure the mixture doesn’t boil.

Oats, seeds and dried fruit being mixed in pan for step 2 in the process for making granola bars.

2. Add the oats, seeds and the dried fruit, plus the cinnamon, to the saucepan. Mix until coated.

A slab of oats, seeds and fruit, baked in a slab for step 3 in the process for granola bars.

3. Press the mixture lightly into a lined baking tin and bake for 30 minutes in a preheated oven at 160C.

4. Allow the mixture to cool in the tin completely before you remove and slice into bars.


Substitutions

  • Additions – You can customise these bars however you like with the kind of seeds, nuts and fruit you add into the mixture. Only like raisins? That’s fine. Fancy a sprinkling of choc chips? Go for it!

Leftovers

Store these in an airtight container. 

You can freeze these for another day if you like. Thaw thoroughly before eating.

TYPE OF OATS

I use half jumbo oats and half rolled oats to make these Granola Bars. 

If you only have one type, that should be fine too, but I like the texture that the combination of the two makes – which is crunchy and chewy!

Rolled oats are more likely to be used in porridge. They absorb moisture well and carry flavours. 

Jumbo oats tend to be bigger and crunchier, keep their shape more, and are more likely to be used for biscuits and cereal bars.

Tips

Allow to cool 

Allow the bake to cool completely in the tin before you slice into 12 bars (with a sharp serrated-edge knife), otherwise they will crumble.

Fruit and nuts

Chop these up to the size you like in a mouthful. If you like full raisins and chunky nuts, keep them large, but if you like a bit of everything mixed together in small amounts, chop them more finely.

FAQs

What size tin is best to use for making cereal bars?

I usually use a tin like this for my tray bakes. It measures 20cm x 20cm and gets the best thickness. You can use another size or shape but just be aware your squares might be thinner or thicker.

Do I need to line the tin?

Yes! Make sure you do this so you can get the cereal bars out quicker and without breaking. 

I use this baking parchment or baking paper for almost everything I bake. No sticking, ever.

I buy it in bulk from Amazon so I don’t run out, and it works out cheaper. Be careful not to confuse it with greaseproof paper, which isn’t suitable for no-bake cakes.

Why have my Granola Bars gone hard?

This is probably down to overbaking. Next time, turn your oven down a little and cook them for 5 fewer minutes.

    Tried these today. Mine turned out a bit crumbly but I think it was due to the size of the tin I baked them in. The flavour is absolutely amazing I will definitely be making more to take to work (I don’t think this batch will last the weekend!)

  7. Great review, really we’ll written. The more I hear about this cookbook from Mumsnet the more impressed I am. These lunch box bars look great. GG

  8. I am so making these lunchbox bars! They look lovely. I have to say you did very well getting your twins to help with so much! Hmm, family meals are usually made from a book I made which is basically scraps of recipes cut out of newspapers or magazines stuck into a file! Not very inspiring!! X
