In a small pan bring the apple juice to the boil. Add the millet and reduce to simmer. Cover the pan and cook for 20 mins until the millet is still slightly firm in the centre. Set aside to cool a little.
Preheat the oven to 180C.
Toast the coconut over a medium heat in a small frying pan for a few minutes until it turns slightly golden. (Coconut burns easily so watch the pan and stir continuously)
In a bowl combine the millet flour with the baking powder, cooked millet and blueberries. Mix together eggs, vanilla essence and oil and once it's well combined stir it into the dry mix. Pour the muffin mix into greased muffin trays and bake for 25 minutes.
