Preheat your oven to 200 C (400 F), spray a 12 cell standard muffin pan with non stick spray or line cups with foil or paper baking cups. Measure out the mini chocolate chips and set them aside.

In a mixing bowl, add the flour, brown sugar, cocoa powder, baking powder, cinnamon, and salt. Whisk to mix together.

In another bowl, add the milk, applesauce, egg, butter, and vanilla, whisk together.

Pour the milk mixture into the dry ingredients, stir until just combined, a few dry spots is ok as you will stir one more time.

Add the mini chocolate chips and stir them in until just mixed through.

Spoon the batter evenly into the prepared muffin pan.

Bake for 13-15 minutes or until a toothpick inserted in the center comes out clean. Remove from the oven and allow to cool in the pan for 5 minutes. (I checked at 14 minutes and they were perfect.)

After 5 minutes, remove from the pan and allow to completely cool on a wire rack.

Serve and enjoy.
