You can make cranberry oatmeal bars with seven store cupboard ingredients in under an hour. 

Unlike flapjacks, these cranberry oatmeal bars use light brown sugar for a subtle caramel taste when baked. Plus, the mixture had chopped nuts and seeds for a crunchy finished texture and some soft, plump cranberries for a sour contrast to the sweet oats. 


  • 150g porridge oats
  • 75g sunflower seeds
  • 100g chopped hazelnuts
  • 75g unsalted butter
  • 3tbsp honey
  • 50g light brown sugar
  • 70g dried cranberries




  1. Heat the oven to 160C (140C fan, Gas 3) and line a buttered tin with baking paper.
  2. Sprinkle the oats, seeds and hazelnuts on a baking tray and toast for 5 mins until lightly golden and aromatic.
  3. Meanwhile, in a saucepan warm the butter, honey and sugar until melted. Stir gently to combine.
  4. Add the toasted oat mix and cranberries and mix to make sure everything is well coated.
  5. Pour the mixture into the prepared lined tin and press down into an even layer. Make sure the mixture is in all the corners and right up to the edges of the tin.
  6. Bake for 30 minutes then allow to cool completely before you cut into 12 bars.

Top tips for making cranberry oatmeal bars

Whether you need inspiration on how to serve you cranberry oatmeal bars or you’d like some suggestions for substitutions, we have plenty of tips below. 

What can I use instead of dried cranberries?

You can swap cranberries for dried cherries, raisin or sultanas. You could also use dried apricots, figs and dates. USe the combination of fruit and nuts you like best. Peanuts also make a cheap but tasty addition. 

What to serve with cranberry oat bars?

You can enjoy these bars on their own but you could also serve them with a dollop of yogurt for a tasty breakfast or dessert. If you want something more indulgent, consider serving with some double cream, custard or even a scoop of vanilla ice cream. 

Should I buy roasted chopped hazelnuts?

Lots of supermarkets sell chopped nuts that have already been roasted. They are much tastier than nuts that have not been roasted. However, if they are more expensive we recommend buying the unroasted version and making a big batch at home yourself. 

These cranberry oatmeal bars make a delicious picnic snack. If you don’t have lots of room in your bag for tubs of snacks, consider purchasing some reusable, sealable silicone food bags. They are lightweight and better for the environment than single use clingfilm.
