Optional: 1/2 cup chocolate chips (I used mini-chocolate chips in the picture)
*DO NOT follow the instructions or use the ingredients on the back of the cake mix box.
Add the cake mix, pumpkin puree, and applesauce to a large bowl. Mix well either by hand or with a hand mixer. When thoroughly blended, fold in chocolate chips (if using). The batter will be pretty dense.
Line a cupcake tin with cupcake liners and lightly spray each liner with non-stick cooking spray. Spoon batter into each liner until it is about 3/4 of the way full (I was able to get about 12-14 muffins). The shape of each muffin will be a little irregular because of the density of the batter.
Bake according to the directions on the back of the cake mix box (I baked mine at 350 degrees for 18-22 minutes). Stick a toothpick in the middle of muffin to make sure the middles are done.
