Peel 1 banana and add the flesh to a mixing bowl. Mash with a fork until smooth and no large lumps remain.
Repeat with the rest of the batter, adding a little more oil to the frying pan if the pancakes begin to brown too quickly or start to stick. You should make about 8 pancakes in total.
Peel and slice the remaining banana. Serve the pancakes in a stack with the slices of banana, a sprinkling of extra blueberries and a generous drizzle of maple syrup. Then get stuck in.
