Preheat the oven to 350°F (175°C). Place paper liners in a 12-cup muffin pan, or lightly grease each cup so the muffins come out easily.

Crack the eggs into a large mixing bowl. Add the milk, maple syrup or honey, melted butter, and vanilla extract. Whisk until the mixture looks smooth and everything is well blended.

Pour in the Kodiak Cakes Buttermilk Power Cakes Mix. Add the ground cinnamon and salt, then stir gently until you no longer see dry flour. Avoid mixing too much, as this can make the muffins dense.

Add the mini chocolate chips and gently fold them into the batter using a spatula. Keep a small handful aside to scatter over the muffins before they go into the oven.

Spoon the batter into the prepared muffin cups, dividing it as evenly as possible. Fill each cup about three-quarters full, then sprinkle the reserved chocolate chips on top.

Bake for 18–22 minutes on the center rack. The muffin tops should look lightly golden and feel set. Insert a toothpick into the middle of one muffin; it should come out without any wet batter.

Take the muffin pan out of the oven and let the muffins sit for 5 minutes. Then gently lift them out and place them on a wire rack to cool.

Enjoy the muffins while they are still slightly warm, when the chocolate chips are soft and melty. If you plan to save some for later, let them cool completely before placing them in an airtight container.
