Banana Pancakes with Blueberries

This are pancakes you usually eat with rashes of bacon and no blueberries, but I wanted them sweet without any pork.
It is good to make the batter an hour before you bake them, they get more fluffy this way. A splash of seltzer water or carbonated mineral water helps even more.

Recipe
270 g flour
2 egg
300 ml milk
1 1/2 tsp baking powder
30 g butter
1 pinch of salt
2 tbsp brown sugar
2 small or 1 large banana mashed

1 splash of carbonated water just before you pour batter in the pan

oil for the pan
fresh blueberries
Maple syrup

Store the ones you just baked in an oven at 50 C and stack the others on top. It will take a while until you have made all the batter into pancakes.
4 blueberries per pancake work fine.
