Peel the bananas, add them to a medium bowl and mash with a fork or masher until they become a thick paste.
Add the Greek yoghurt, egg, milk, and vanilla extract to the mashed banana and mix well.
In another medium bowl, add the buckwheat flour, baking powder, cinnamon, nutmeg andchia seeds. Give the dry ingredients a quick mix with a fork.
Pour the dry ingredients into the bowl with the wet ingredients. Gently fold the dry ingredients into the wet ingredients until just combined. Be careful not to overmix otherwise, you will end up with dense, rubbery pancakes! Don't worry about lumps, this is likely chunks of banana. (Note 6)
Heat a large non-stick frying pan over medium heat. If your non-stick pan is not as non-stick as it used to be, keep a teaspoon of extra virgin olive oil next to you and greased the frying pan using a pastry brush after every 2-3 pancakes.
Scoop 1 ladle full of batter and pour it into the hot frying pan (I used a metal spoon to scrape the batter out of the ladle). Spread the batter out to your desired thickness using the back of the ladle or a spoon.
Cook the pancake for roughly 2 minutes or until the batter gets a lot of bubbles. If thesides stick to your spatula when you go to flip, it's not ready yet. Flip the pancake over and cook for another 1-2 minutes. Once cooked, flip the pancake onto a plate, set aside and repeat steps 6 and 7 until you have no batter left.
Serve topped with some fruit, nuts, or other favourite toppings!
