Place all batter ingredients in a strong blender (I used my Vitamix), in the order listed. Blend until a smooth liquid has formed, about 30 seconds.

Heat a griddle over medium low heat. Lightly coat the griddle with the cooking spray.

Pour batter, about 1/4 cup at a time on the griddle, leaving space between each pancake. Cook until bubbles start to form on the top of the pancakes, about 3 minutes.

Flip the pancakes and cook until the bottom is golden, about 3 more minutes. Repeat with the remaining batter.

Serve hot, topped with maple syrup or fresh fruit, if desired.
