In a large bowl, mix the mashed banana, eggs, maple syrup, lemon juice, and lemon zest together with a whisk or fork until very well mixed.
In another bowl, mix together the baking soda, almond flour, tapioca flour, coconut flour, and poppy seeds.
Pour the bowl of dry ingredients into the wet ingredients and mix. Add 1/4 cup of almond milk to the batter and mix. Let the batter sit for a few minutes.
Then, heat some oil in a large pan over medium heat. I found a little bit higher than medium heat to be best, but not medium-high, though this will depend on your stove. Put 2 Tbs sized spoonfuls of the batter onto the pan. Cook for about 2 minutes per side, flip, and cook for another minute or so.
(note: cooking time may vary depending on your stovetop)
Yields 5 pancakes, this could serve 1-2 people.
