Prepare the flax egg by combining 1 tbsp ground flax with 2.5 tbsp water and set aside. Skip if using a regular egg.
Add the oat flour, almond flour, arrowroot powder, baking powder, baking soda, and poppy seeds to a large bowl and mix well.
Add in all remaining ingredients including the flax egg (once it has thickened-takes about 5-10 minutes) and mix well.
Heat a skillet or griddle on medium heat (greased if needed), and add 1/3 cup of batter.
Let cook on each side for about 2 minutes or until bubbles start to form around the edges.
Repeat until all batter has been used. Serve with fresh berries, maple syrup or coconut whipped cream!
