Preheat the oven to 350°F (175°C).
Grease a bundt cake pan with baking spray and dust with flour, tapping out the excess.
Make the Batter:
In a large mixing bowl, combine the chocolate cake mix, pudding mix, sour cream, eggs, oil, water, and vanilla extract.
Mix until smooth and well combined.
Fold in the chocolate chips, ensuring even distribution.
Bake the Cake:
Pour the batter into the prepared bundt pan and smooth the surface with a spatula.
Bake for 50-60 minutes, or until a toothpick inserted into the center comes out clean.
Cool and Serve:
Let the cake cool in the pan for 10-15 minutes, then invert onto a wire rack to cool completely.
Optionally, drizzle with chocolate ganache or dust with powdered sugar before serving.
