In a large bowl, whisk together egg, buttermilk, canola oil, and maple syrup until well blended.
Add whole wheat flour, oats, cinnamon, and baking powder to bowl and mix until combined (do not overmix). Add in blueberries and stir.
Let batter sit for 5-10 minutes. In the meantime, heat griddle or pan at medium-high heat.
Pour batter in pan and flip when bubbles form on top of surface. Cook on other side for 1-2 minutes or until light brown.
Enjoy with a drizzle of real maple syrup.
