In a blender, place the bananas, eggs, almond milk, oats, baking powder and salt. Blend on high until smooth, 1 to 2 minutes. Allow the batter to rest for 5 minutes to thicken slightly.
Meanwhile, spray a nonstick skillet or griddle with cooking spray and heat over medium-high heat. For each pancake, scoop ¼ cup of batter onto the skillet. Sprinkle blueberries on top of the batter.
Cook 2 to 3 minutes or until bubbles begin to appear on top. Flip the pancakes over and cook for 1 minute on the other side, or until golden brown.
