1. Preheat the oven to 180ºC fan-forced.
2. Place the rolled oats, almond meal and shredded coconut into a food processor and process until texture is a coarse flour.
3. Transfer the mixture to a large bowl and add in the baking powder and cinnamon and mix again.
4. In a separate bowl, combine the wet ingredients (except the blueberries).
5. Make a well in the centre of the dry ingredients and pour in the wet ingredients and mix until well combined.
6. Place half the mixture into a lined baking tray and press down to ensure it is evenly spread and firm then top with the blueberries.
7. Pour over the remaining mixture on top of the blueberries to create a crumble-like topping (or a blueberry sandwich).
8. Bake in the oven for 25-30 minutes until slightly golden on top.
