Spinach Banana Muffins (Baby & Toddler Friendly)

1 Preheat the oven to 375°F (190°C) and line a muffin tin with paper liners or grease lightly.
2 In a blender, add the banana, spinach, milk, yogurt, melted butter, eggs, and vanilla. Blend until completely smooth.
3 Add in the oats, cinnamon, baking soda, and salt. Blend again until combined.
4 Transfer the batter to a bowl and gently fold in the whole wheat flour until just combined. Do not overmix.
5 Divide the batter evenly among the muffin cups (about 12 muffins).
6 Bake for 18–20 minutes, or until a toothpick inserted into the center comes out clean.
7 Let muffins cool for 5 minutes in the pan, then transfer to a wire rack to cool completely.
