Combine all ingredients except for the blueberries and stir until well mixed. Gently fold in blueberries.
In a skillet sprayed with nonstick spray, drop batter into pan to form 3 pancakes (or 1 big pancake). Once pancakes begin to look solid (about 3 minutes), gently flip (if possible, re-spritz the pan with nonstick spray as you flip 'em to prevent sticking). Cook for approximately 3 additional minutes, or until both sides are lightly browned and insides are cooked through.
