Heat oven to 350 degrees. Line a muffin pan with cupcake liners or spray with non-stick cooking spray. Set aside.
In a large bowl, whisk together the cake mix, oil, eggs, and water until combined. Be sure to use only half the water that the cake mix box calls for.

Add pumpkin puree to the cake batter and whisk to combine.

Add the pumpkin cake batter to your muffin tins, filling each cup about ⅔ full. Bake for 15-20 minutes in the preheated oven, then place on a wire rack and allow to cool completely.
In a large mixing bowl, beat the softened cream cheese with an electric mixer on medium speed until smooth.

Add the powdered sugar, cinnamon, and vanilla extract. Mix well to combine.
