Mash banana with a fork in a small bowl. Try to remove all lumps.
Add eggs, egg whites, chia seeds, oat flour and cinnamon, mixing together until well-combined.
Heat a large skillet over medium-high heat.
Once the pan is hot, spray with nonstick spray. Add 1/4 cup of pancake batter to your pan. Let cook for about 2-3 minutes on both sides, carefully flipping. Repeat until all batter is used. Enjoy warm with pure maple syrup, fresh fruit, and/or nut/seed butter!
