Healthy Double Chocolate Banana Muffins

0 Preheat your oven to 350°F (175°C). Line a muffin tin with paper liners or grease it lightly.
1 In a large bowl, mash the ripe bananas using a fork.
2 Add honey or maple syrup, melted coconut oil, egg, and vanilla extract to the mashed bananas. Mix well until everything is well combined.
3 In a separate bowl, whisk together whole wheat flour, cocoa powder, baking powder, baking soda, and salt.
4 Add the dry ingredients to the wet ingredients and stir until just combined. Avoid overmixing.
5  Fold in the Greek yogurt, dark chocolate chips, and chopped nuts if using.
6 Spoon the batter into the prepared muffin cups, filling each about 2/3 full.
7 Bake in the preheated oven for 18-20 minutes or until a toothpick inserted into the center of a muffin comes out clean.
8 Allow the muffins to cool in the tin for a few minutes before transferring them to a wire rack to cool completely.
