Preheat the oven to 350ยบ. Spray the bundt pan with Baker's Joy spray.
Combine chocolate cake mix, granulated sugar and pudding mix in a large bowl.
Add eggs, oil and water to the dry ingredients and mix until well combined and there are no more lumps.
Add the sour cream and chocolate chips to the batter and stir until blended.
Pour the batter into the bundt pan. Tap the pan on the counter to even out the batter a bit.
Bake for 50 minutes, or until a toothpick test comes out clean.
Cool on a cooling rack for about 10-15 minutes, then flip out of the pan to cool completely.
Serve alone, or with some ice cream or whipped cream and fresh berries, if desired.
