Preheat the oven to 350°F, and line two muffin pans with cupcake liners. Spray the liners with cooking spray and set aside.
In a large mixing bowl, whisk together the cake mix, cinnamon, ginger, cloves, and nutmeg.
15.25 ounces spice cake mix, 1 tsp. ground cinnamon, 1 tsp. ground ginger, ½ tsp. ground cloves, ½ tsp. ground nutmeg
Pour in the eggnog, eggs, oil, and molasses. Use an electric mixer to beat the ingredients until well combined and smooth, about 1 minute.
¼ cup unsulfured molasses, ¾ cup eggnog, ⅓ cup canola oil, 3 large eggs
Use a medium cookie scoop to fill each cupcake liner about ½ full, just under ¼ cup.
Bake for 16 to 18 minutes until a toothpick inserted in the center comes out clean or the top of the cupcake springs back when lightly pressed.
Allow the cupcakes to remain in the pan for about 5 minutes before transferring to a wire rack to cool completely.
