Preheat oven to 350F. Prepare a 12 cup muffin tin lined with paper cups.
In a medium size bowl, mash bananas well and add sugars, applesauce, milk, vinegar and yogurt. Blend well.
In another bowl, mix flour, baking soda, salt and cocoa powder. Add dry ingredients to wet ingredients and mix just until incorporated. Do not over mix.
Add in half a cup of the chocolate chips and mix again just until the chips are distributed evenly. Using an ice cream scoop, divide batter into 12 muffin cups equally. Top with remaining chocolate chips.
Bake for 22-25 minutes or until done when tested with a toothpick. Serve either warm or at room temperature.
