Preheat the to 350 degrees F.
Grease and flour a 12-cup bundt pan.
Add the oil, cocoa powder, salt, and water to a saucepan over medium heat. Heat the mixture slightly, stirring to combine.
Add the butter to the mixture. When it's fully melted and combined, remove the chocolate mixture from the stove.
Add the all-purpose flour, granulated sugar, and baking soda to a large bowl and whisk to combine.
Add half of the chocolate mixture to the dry ingredients and whisk until completely blended.
Add the remaining butter mixture and whisk until combined.
Add the remaining flour mixture and mix just enough to combine.
Add the eggs to the batter, one at a time, whisking until incorporated. Scrape the bottom and sides of the bowl with a rubber spatula between additions. Add the sour cream and the vanilla extract, stirring just enough to combine into a smooth batter.
Add the chocolate chips to the cake batter, stirring to combine.
Pour the batter into the prepared pan.
Place the pan on the center rack of the preheated oven and bake for 40- 45 minutes or until a toothpick inserted into the center of the cake (or a cake tester) comes out clean.
Place the pan on a wire rack and let it cool in the pan for 15 minutes; then invert it onto the rack to finish cooling.
