Preheat the oven to 150 °C/ 300 °F (fan assisted).
Roughly chop the almonds, pecans and brazil nuts and place in a mixing bowl.
Add the chia, pumpkin, sunflower flax and hemp seeds and combine.
Add protein powder, vanilla, erythritol, and salt.
(If using maple syrup, add in step 3.) Blitz about a 3/4 of the blueberries in a high speed blender until like a coulis.
Keep the remaining blueberries for topping.
Add egg white, coconut oil and blitzed blueberries.
Mix.
Evenly spread the mix onto a 30 x 20 cm (12 x 8 inch) baking tray.
Top with the remaining blueberries.
Bake in the oven for about 35 minutes.
Add the flaked coconut and bake for a further 8 minutes until golden.
(You do need to add the flaked coconut later or it may burn.) Remove from the oven and allow to cool.
Break up with a fork and let it cool down.
Serve with yoghurt, sour cream, unsweetened almond milk, cashew milk or coconut whipped cream.
You can even add a drizzle of more blitzed blueberries and a few whole blueberries.
