It's pretty simple to make muffins using cake mix. They'll be denser and sweeter than regular muffins. The most common way to make them is to use applesauce as an easy alternative to oil and eggs.
Spray a muffin tin with nonstick cooking spray. You can also use paper liners if you prefer.
Preheat the oven to 350 degrees Fahrenheit.
Add cake mix to a medium or large mixing bowl. Stir in applesauce and water and mix until all of the ingredients are fully incorporated.
Fill each greased muffin cup about 2/3 full with the batter.
Bake for 15 minutes, or until a toothpick inserted in the middle of a muffin comes out clean.
Cool the finished muffins for 5 minutes in the muffin tins.
Transfer muffins to a cooling rack and let them cool for 5 more minutes before serving.
