Preheat a medium skillet or griddle over medium heat. Lightly grease with cooking spray.
In a blender or food processor, add all ingredients except the blueberries. Blend until completely smooth, adding more liquid if desired for thinner pancakes.
Let the batter sit for 5 minutes.
Add blueberries; stir to incorporate evenly.
Use about 2 tablespoons of batter to form each pancake. Cook on one side until bubbles begin to form, about 3-5 minutes. Flip and cook about 3-5 more minutes.
Serve with a drizzle of maple syrup and peanut butter, and top with extra blueberries!
