PREP: Preheat the oven to 350 degrees F. Spray all 12 cavities of a muffin tin with cooking spray and lightly flour. Shake out any excess flour and set aside.
WET INGREDIENTS: Mash 2 very ripe bananas to get 1 level cup of mashed banana (See Note 2). Mash well to get rid of any/all chunks. Add to a large bowl. Add in the large egg, 1/2 cup melted and cooled coconut oil, 1/2 cup honey, 1/4 cup Greek yogurt, and 1 and 1/2 teaspoons vanilla extract. Whisk until combined and smooth.
DRY INGREDIENTS: In a separate bowl add the 1 teaspoon baking soda, 1 teaspoon baking powder, 1 teaspoon cinnamon, and 1/2 teaspoon sea salt to a large bowl. Add in the 1 and 3/4 cup flour (spoon flour into the measuring cup and level the top) and optional 1/2 cup nuts or miniature chocolate chips. Stir until combined. Add wet into dry ingredients. Mix until just combined. Do not overmix; this will cause deflated or dense muffins.
BAKE: Divide the batter evenly between the 12 muffin cups. Each muffin cup should be pretty much filled to the top and all the batter should be used. IF desired, add a sprinkle of coconut on top of each muffin. Bake for 18-23 minutes or until a toothpick when inserted into the center comes out dry or with a few moist crumbs. Remove and allow to cool for 5 minutes before removing the muffins from the pan and transferring to a cooling rack.

Notes
Note 1: Add-ins: We love these muffins and have tried them so many different ways! We've made them plain without anything added in or on top, with miniature chocolate chips mixed through, with chopped nuts mixed through, and with coconut on top. The step by step pictures in the post show the process for making these muffins plain. The first and last shot in the post showcase the muffins with coconut flakes added before baking.Note 2: Bananas: To make sure the banana is mashed really well and you don't end up with big chunks in your muffins, mash the ripe bananas with a hand or stand mixer. To do this, peel the bananas, break them into large chunks, and beat them with the mixer until well mashed.
