Grind the oats using any grinding machine. I used a Nutribullet; it was quick and efficient (and available!)
Peel the banana and crush it using a fork—the riper the banana, the sweeter the taste.
Add the sugar, spices and egg yolks. Mix using a hand-held mixer until it becomes creamy.
Add the milk and incorporate well with a spoon.
Add the ground oats and mix again.
Separately, add some salt to the egg whites. Beat with a hand-held mixer at high speed until they form stiff peaks.
Add to the creamy mixture and stir slowly until it becomes homogenous.
Optionally, add a handful of seasonal fruit.
Preheat a pan and add a few drops of rapeseed oil or coconut oil.
If you have a shaped gadget or a heart-shaped pan, use it. If not, place one spoonful of the mixture into the heated pan. Cook for two minutes, then flip over and cook for another two minutes or until ready.
When cooked, transfer the first pancake on a plate and repeat the process until you use the entire mixture.
Best served warm, with a dollop of quality maple syrup and a handful of fresh or dried fruit, depending on the season.
