Preheat oven to 350°F (175°C) and grease a standard 12-cup muffin tin or line with paper liners.
In a large mixing bowl, whisk together the egg, milk, honey, applesauce, and vanilla extract until smooth.
Add the Kodiak Cakes mix to the wet ingredients and stir until just combined; do not overmix.
Gently fold in the chocolate chips.
Distribute the batter evenly among the 12 muffin cups, filling each about three-quarters full.
Bake for 15 to 18 minutes, or until a toothpick inserted into the center of a muffin comes out clean.
Allow muffins to cool in the tin for 5 minutes before transferring to a wire rack to cool completely.
