- Preheat the oven to 180ΒΊC, gas mark 4, and line a 20cm square cake tin with baking parchment.
- In a large bowl, mash the bananas with a fork. Whisk in the oil and honey, then stir in the oats, sunflower seeds, cinnamon and a pinch of salt until combined. Gently stir through the blueberries, then tip the mixture into the tin and smooth the top with a spoon.
- Bake for 40-45 minutes until deep golden. Remove from the tin and cool completely before slicing in to bars. Store in an airtight container for up to 1 week.
Cookβs tip
Scatter leftover sunflower seeds over soups and salads for extra crunch and nuttiness, or use to top porridge or yogurt.
