Mix all dry ingredients in a bowl: oat flour, coconut flour, baking powder, baking soda, and poppyseeds.
Mix all wet ingredients in a separate bowl: egg, almond milk, lemon juice, vanilla, and coconut oil.
Combine wet ingredients and dry ingredients. Add lemon zest and shredded coconut (if using).
Heat a pan coated with coconut oil over medium heat.
Use about 3 tbsp of batter for each pancake. Flip when there are bubbles on the pancake's surface and cook for approximately 2-3 minutes per side.
Get fun with toppings! I microwaved some blueberries and mixed them with greek yogurt. Other toppings: lemon zest, peaches, coconut butter drizzle.
