Preheat the oven to 350°F (175°C). Line a 12-cup muffin tin with paper liners or grease with non-stick spray.
In a large bowl, whisk together Kodiak Cakes Power Cakes mix, baking soda, ground cinnamon, and salt until well combined.
In a separate medium bowl, combine mashed bananas, eggs, Greek yogurt, honey, applesauce, and vanilla extract. Mix until smooth.
Pour the wet ingredients into the dry ingredients and stir gently until just combined. Do not overmix; some lumps are okay.
Divide the batter evenly among the 12 muffin cups, filling each about 3/4 full.
Bake for 18 to 20 minutes, or until a toothpick inserted into the center of a muffin comes out clean.
Remove the muffins from the oven and let them cool in the tin for 5 minutes, then transfer to a wire rack to cool completely.
