1. 1.
   Preheat oven to 425°F (218°C). Spray a 12-count muffin pan with nonstick spray or line with cupcake liners. Set aside. 
2. 2.
   In a medium bowl, whisk the flour, cinnamon, baking soda, baking powder, and salt together. Set aside.
3. 3.
   In a large bowl, whisk the mashed bananas, honey, yogurt, coconut oil, egg, and milk together until combined. Then whisk in the peanut butter and vanilla extract until smooth.
4. 4.
   Pour in the dry ingredients and stir gently until just combined—you can start with a whisk and then switch to a spatula if it becomes too thick to whisk. Try not to over-stir the muffin batter or your muffins will have a tough (not soft) texture. Fold in the mini chocolate chips (if using). The batter will be thick.
5. 5.
   Spoon the batter into the muffin cups, filling them to the top. Bake for 5 minutes at 425°F, then, keeping the muffins in the oven, reduce the oven temperature to 350°F (177°C). Bake for an additional 15 minutes or until a toothpick inserted in the center comes out clean. The total time these muffins take in the oven is about 20 minutes, give or take. Allow the muffins to cool for 5 minutes in the muffin pan, and then transfer to a wire rack to continue cooling.
6. 6.
   Drizzle muffins with melted peanut butter, if desired.
7. 7.
   Muffins stay fresh covered at room temperature for a few days, then transfer to the refrigerator for up to 1 week.
