If using a food processor, process the oats for about 1 minute until they resemble flour.
Add the flaxseeds, eggs and bananas to the oats and process until a batter is formed. It shouldn't be too thick or runny. If it's very watery add some more oats.
If using a hand blender, put the oats, flaxseeds, eggs and bananas into a bowl and blend to form a batter (you will just have chunkier oat pieces in your pancakes if doing it this way).
Heat the frying pan or skillet over a low-medium heat. Once hot, add the oil. There should just be a light covering of oil in the pan. If there's too much, carefully (don't burn your hand!) wipe it with a paper towel to get rid of the excess.
Add about ¼ cup / 1 ladle full of batter to the pan. You'll have to do this in batches. I usually fit about 4 in my pan at a time. Leave them until small bubbles start to form in the batter. About 2-3 minutes (see notes).
Flip them over and continue cooking for another 2 minutes.
Repeat for the rest of the batter.
Serve with toppings of your choosing. I always use my mixed berry compote - you can find the recipe here. You could also use honey, maple syrup, yoghurt or fresh berries. Yum!
