Step 1

Preheat the oven to 425 degrees F. Prepare a muffin pan with cooking spray or line it with parchment paper muffin liners. I like to use a silicone muffin pan and then there's no need to spray it or use muffin liners. I also like to dust the muffin pan cavities with a little cocoa powder.

Step 2

Mix wet ingredients together until well combined: ripe mashed bananas, honey, egg, oil and vanilla.

Step 3

Add dry ingredients to wet ingredients: flour, cocoa powder, baking powder, baking soda, cornstarch and salt. Mix until just combined. Over-mixing will result in denser muffins. Stir in chocolate chips. I used 1/2 cup semi-sweet chocolate chips (Trader Joe's) and an additional 1/4 cup mini chocolate chips (Enjoy Life).

Step 4

Pour batter into muffin cups (about a heaping 1/4 cup batter per muffin) and sprinkle additional 3 or 4 regular-sized chocolate chips over the tops of the muffins.

Step 5

Bake muffins for 5 minutes at 425 degrees F. and then with muffins staying in the oven, reduce heat to 350 degrees F. and bake muffins for 13-15 minutes more. The high heat will cause muffins to rise and then you will lower heat to cook the center of the muffin.

Step 6

Remove from oven and allow to cool in the pan for 10 minutes before transferring to a wire rack to cool completely.
