In a large bowl, add buckwheat flour, baking powder, cinnamon powder, and salt. Mix well and set aside.
In another bowl, add banana, and using a fork, mash well until you get a puree.
Pour almond milk, agave, and vanilla extract. Mix well.
Add the banana and almond milk mixture to the dry ingredients and mix well until everything is just combined. Don’t over-mix the batter. Some lumps are alright.
Place a frying pan on medium heat. Brush it with oil.
Scoop 1/3 cup of the batter and pour it on the frying pan.
Let it cook for about 2 minutes. Once you see small bubbles appear on the surface of the pancake, flip it using a spatula for cooking it on the other side for about 3 minutes.
Serve!
