Healthy Oat Cookies with Mixed Berries

These Healthy Oat Cookies with Mixed Berries are naturally sweetened with ripe bananas and berries, making them a simple option for breakfast, afternoon tea or a mid-day snack. Despite containing no added sugar, oil, eggs or dairy, they have a soft texture and plenty of natural sweetness from the fruits. The ingredients also bring their own nutritional benefits. Oats provide fibre and plant-based protein, chia seeds contribute calcium, nuts and seeds add magnesium and healthy fats, while bananas supply potassium and vitamin B6. The berries add colour, flavour and a variety of vitamins and antioxidants. The recipe is easy to adapt depending on what you have available. Fresh or frozen berries both work well, and you can use raspberries, blackberries, blueberries or a mixture. Chopped nuts and seeds add texture, while the oats and chia seeds help create a satisfying cookie that keeps well for several days. You can bake them either the oven or the air fryer. Notes
  • Walnuts, almonds, hazelnuts, pistachios, pumpkin seeds or sunflower seeds are all good choices.
  • If using frozen berries, there is no need to thaw them first, although you may need a few extra oats if the mixture becomes too wet.

Ingredients Method

Ingredients
  

  • 3 small ripe bananas
  • 2 cups oats plus extra if needed
  • 1 cup mixed berries chopped, mashed or lightly crushed
  • 1 tsp vanilla extract
  • 1 tsp ground cinnamon optional
  • 1 tsp ground chia seeds
  • ½ cup chopped nuts or seeds

Method
 

  1. Preheat the oven to 180°C and line a baking tray with baking parchment.
  2. Mash the bananas in a large mixing bowl.
  3. Add the berries and gently crush them with a fork to release some of their juices.
  4. Stir in the oats, ground chia seeds, vanilla extract and cinnamon, if using.
  5. Mix well to combine. If the mixture seems too wet or loose, add a little more oats until it is firm enough to shape.
  6. Fold in the chopped nuts or seeds.
  7. If time allows, leave the mixture to rest for 10 minutes so the oats and chia seeds can absorb some of the moisture.
  8. Divide the mixture into approximately 12 portions. Shape each portion into a ball, then flatten slightly to form cookies.
  9. Arrange the cookies on the prepared baking tray.
  10. Bake for about 20 minutes, or until lightly golden around the edges.
  11. Leave to cool on the tray for a few minutes before transferring to a wire rack to cool completely.
  12. Air Fryer Method: place the cookies on the air fryer rack or in a lined air fryer basket, leaving a little space between them. Bake at 180°C for 12–15 minutes, turning once halfway through cooking.
  13. Leave to cool before serving.
