Make this healthy flapjack recipe and you’ll have the perfect post-workout snack or a new breakfast option for when you’re on the go.  

Flapjacks are a delicious treat but the best thing about our healthy flapjack recipe is that it only uses naturally sweet ingredients such as dates. This makes them lower in fat compared to the traditional bake and under 100 calories too. Make a batch of these at the beginning of the week and then slice them into portions for a healthy breakfast each morning. We use a combination of hazelnuts and walnuts but you can use your favourite mix of nuts and seeds. 


  • 200g mixed nuts (1 ⅓ cups) mixed nuts (we used hazelnuts and walnuts)
  • 50g mixed seeds (⅓ cup) mixed seeds (we used chia, sunflower and pumpkin)
  • 75g (½ cup) jumbo oats
  • A pinch of ground cinnamon
  • A pinch of salt
  • 50g (⅓ cup) coconut oil)
  • 30g goji berries
  • 4-5 Medjool dates, stoned and roughly chopped
  • Dash vanilla extract
  • Zest 1 orange




  1. Heat the oven to 180C (160C fan, Gas 4). Once hot, spread the nuts on a lined baking tray and cook for three minutes. Add the seeds and toast for two more minutes
  2. Allow the nuts and seeds to cool slightly, then tip them into a food processor with the oats, cinnamon and salt.
  3. Meanwhile, warm the coconut oil in a small saucepan, then add the goji berries and dates and let them soften. Add the vanilla extract and the orange zest.
  4. Add this warm mixture to the food processor and blend. Wait five minutes and then blitz again. It will blitz more finely once cooler.
  5. Line an airtight food container or small baking tray (21 x 14cm) with greaseproof paper. Tip in the mixture and flatten using a spoon, palette knife or even the palm of your hand.
  6. Cover and chill in the fridge for at least four hours, but ideally overnight.

Top tips for making healthy flapjacks

Vegan bakes often have a different texture compared to their traditional counterparts. If your healthy flapjacks aren’t holding their shape we’ve got some tips below that will fix this, plus tasty topping suggestions too.

Why are my healthy flapjacks falling apart?

You may not have softened dates and goji berries enough. Softening in warm coconut oil is an essential step and shouldn’t be rushed or skipped. The date, goji berry, and coconut oil mixture is the ‘glue’ in our healthy flapjack recipe and replaces the golden syrup which acts as the binding ingredient in our traditional flapjacks. 

Once soft and while still warm, the date, goji berry, and coconut oil mixture should be thoroughly blended to a fine paste. Depending on your food processor's power and speed this may take longer than the recipe states. If the mixture is struggling to come to a fine paste you could add a teaspoon or two of orange juice or smooth peanut butter to help loosen it. 

You should also make sure the mixture is densely packed into your chosen tray or container. If you don’t apply enough pressure, the mixture won’t stick together and set in an even layer. 

These flapjacks are best stored in an airtight container in the fridge due to their soft texture.

What can I add to flapjacks?

To make these healthy flapjacks even tastier, why not make a delicious topping for them? In a small pan combine 6 tbsp coconut oil with 5 tbsp cacao powder and 2 tbsp maple syrup or honey if you don’t require the recipe to be vegan. Stir over low heat to remove any lumps, then pour over the top and set in the fridge. 

You can also experiment with the nut, seed, and fruit combination. Dried apple is a nice replacement for goji berries and compliments the ground cinnamon. For a more autumnal, cosy flavour consider adding some ground ginger too. You could also swap the orange zest for vanilla or almond extract. 

Food writer Jessica Ransom recommends roasting your nuts in big batches and storing them in an airtight container so they are ready to be used in future recipes. Toasting nuts and seeds is absolutely crucial for the overall flavour of these healthy flapjacks! It also helps to dry out the nuts and give the finished flapjacks a crunchier texture. 

Why are flapjacks so high in calories?

Traditional flapjack recipes often contain lots of butter, sugar, and syrup which are all high in calories and fat. Our healthy flapjack recipe is also high in calories and fat because it contains a large volume of nuts which are naturally high in fat. Even though this recipe contains only natural sugars and fats, and is high in protein thanks to the nuts and seeds, it’s still important to consume in moderation for a well-balanced diet. 

Food Writer Jessica Ransom says: ‘Orange and lemon zest is commonly used in baking or dessert recipes. This means that, even though zest is not in itself a sweet ingredient, when we eat it we often associate it with sweet things. I find it helps trick my brain into thinking I’m eating something that is sweeter than it is. For me, the same applies to cinnamon too.’ Eating natural sugars means you’re less likely to experience a sugar crash once you’ve eaten it and you’ll experience a more stable energy uptick.

If you enjoy the nutty flavour profile of this recipe, try our protein flapjacks which have a mix of walnuts, almonds and pecans plus mashed bananas and dried cranberries. Vegan flapjacks make a good option for breakfast because they often contain mostly natural sugars which deliver a stable energy release. Plus, just like our granola bar recipe, they can be cut up and eaten on the go.
