Cooking and preparation time: 35-40 minutes
Ingredients:
For the Oat Layers
- 225g rolled oats 
- 1-2 very ripe mashed banana (medium-large) 
- 25g ground almonds (or any other ground nuts) 
- 3 tbsp water

- 200g fresh blueberries 
- 1 tbsp cornflour

Method:
- Preheat the oven to 180C. Line an 8-inch square baking tray with greaseproof paper, and spray or lightly coat with butter or non-stick cooking spray. 
- For the oat layers- in a food processor, blitz 135g of oats into a fine flour. Then in a large bowl, using a fork combine the oat flour, remaining 90g oats, mashed banana, ground nuts, melted butter, water, salt, and flavourings of your choice until combined and crumbly. 
- For the filling – in a large bowl, using a fork, coarsely crush the blueberries. Sprinkle over the cornflour and optional flavourings if using. Mix well. 
- To assemble, firmly press half of the oat mixture into the prepared pan, patting down. Evenly spread over the blueberry filling, and to finish, coarsely crumble over the remaining oat mixture. 
- Bake in the pre-heated oven for 25-30 minutes, until the filling is bubbling and the topping is golden. 
- Cool completely in the pan on a wire rack. Once cool, cut into bars.
