Measure Oats into a medium bowl and add 1.5 cups boiling water. Let soak for at least 5 minutes. (No need to strain as it will just be absorbed into the oats)
While Oats soak measure out the dry ingredients: flour, flax, baking powder, baking soda, cinnamon & salt into a large mixing bowl. Stir to combine.
Preheat Griddle Pan to 350 degrees or Skillet to Med High (adjust skillet as needed for ideal cook)
Once the oats are done soaking add the buttermilk, honey, butter, vanilla and eggs to the soaking oats bowl. Stir well to combine.
Now add the wet ingredients to the dry ingredients bowl, stir to combine til there are no more large flour clumps visible.
If your electric griddle or pan is done preheating spray cooking oil or lightly coat pan with olive oil.
Use 1/4 Cup measuring cup to scoop batter onto cooking surface.
*Optional- you can drop 4-5 blueberries or other small berries onto the batter at this point if you like.
Cook until undersides start to brown and a bubble pops, about 3 mins (these do not bubble and pop as standard pancakes do so check underneath with spatula if unsure)
Gently flip pancakes and cook again till lightly golden brown, about 3 minutes
Place cooked pancakes in warmed oven at 170 deg. on baking sheet.
