Preheat oven to 350 degrees F. Line a 12 cup muffin pan with muffin liners and spray with nonstick cooking spray to prevent oatmeal cups from sticking.
In a medium bowl, mix together the mashed banana, peanut butter, eggs, maple syrup, almond milk and vanilla until smooth and well combined.
Next stir in dry ingredients: oats, baking powder, cinnamon and salt; stir well to combine. Fold in ⅓ cup chocolate chips into batter.
Evenly distribute oatmeal batter between muffin liners. Sprinkle extra chocolate chips on top and bake for 20-25 minutes. Drizzle with your favorite nut butter before serving, if desired. Serves 12.
