Preheat the oven to 350 degrees.
Grease a 10-12 cup bundt pan. Set aside.
In a large mixing bowl combine the cake mix, pumpkin, water, oil, eggs, and pumpkin pie spice.
Whisk until completely blended.
Lightly grease the bundt pan.
In a medium mixing bowl whisk the filling ingredients- cream cheese, granulated sugar, and egg until well combined and smooth.
Pour half of the pumpkin cake batter into the prepared bundt pan.
Add the cheesecake filling mixture on top of that.
Top with the rest of the cake batter.
Place the bundt pan on a baking sheet and then bake for 45 minutes or until a toothpick inserted comes out clean.
Cool the cake for 10 minutes before inverting it onto a wire rack to cool completely.
Once cool, prepare the glaze.
