Preheat the oven to 350F and line a 12 cup muffin pan with paper liners.

In a large bowl, stir together the flour, sugar, cinnamon, baking soda and salt. Toss in the chocolate chips and set aside.

In a medium bowl, whisk together the mashed bananas, oil, eggs, yogurt and vanilla extract.

Add the wet ingredients to the dry ingredients and mix until just combined.

Bake for 20-23 minutes or until a toothpick inserted into the center comes out clean.
