Step 1

Preheat oven to 350F. Spray muffin tin with cooking spray (I like to also line with paper liners).

Step 2

Place bananas, spinach, milk, oil, eggs and vanilla in a high-speed blender. Blend until smooth.

Step 3

Add oats, coconut sugar, baking soda, baking powder, cinnamon, and salt. Blend again, until oats are fully broken down and the mixture is smooth. Fold in chocolate chips with a rubber spatula, if using.

Step 4

Pour batter evenly into muffin tin. Bake for 23 minutes, or until a toothpick comes out clean. Cool on a wire rack for at least 10 minutes and enjoy!
