Puree the bananas with a fork in a bowl. Whisk the eggs and add the coconut and the blueberries. Keep some of the blueberries behind for serving later.
Heat oil in a frying pan on medium heat. Make sure it is a non-stick pan. Pour 1 large tablespoon of the batter in the pan and start by baking one. I prefer to not add more than 2 in the pan at the same time as it makes it harder to turn them over. Obviously depending on the size of your pan.
Once the top is no longer liquid you turn them over gently with a spatula. It takes about 2 minutes per side to bake. Make a pile of the baked pancakes
Add some grated coconut and blueberries for serving and serve hot.
