Preheat the oven to 350F. In a large bowl, combine eggs, yogurt, maple syrup, olive oil, and mashed banana. Add the flour, oats, salt, baking powder, baking soda and stir to combine. Fold in the chocolate chips.
Spray or grease a standard-size 12 cup muffin tin with cooking spray and divide the batter between each cup (they will be almost full).
Bake in the preheated oven for about 20 minutes, until the top springs back when pressed, or a toothpick inserted in the centre comes out clean.

Notes
*You can use a fork, immersion blender or mixer, but try to take out as many lumps as you can.
