Put the oats, salt, baking powder and vanilla or cinnamon into a blender and pulse until the oats are ground to the texture of coarse wholemeal flour.
Mash the bananas and whisk with the beaten eggs.
Add to the ground oats and pulse until light batter.
If using, line the pan with the egg moulds and grease with a little butter. When hot, drop in 2 tablespoons of batter. Cook for 2 minutes or until bubbles appear and the edges come away from the moulds. Lift away the moulds and turn over the pancakes to cook on the other side.Alternatively, add two tablespoons of banana batter to a nonstick pan and cook as above. Cook only a couple at a time so you can control the heat and turn them easily.
Serve with banana slices and drizzled honey or maple syrup.
