Preheat the oven to 350 degrees F. Grease a 10-inch tube pan with butter.
This decadent dessert starts by combining butter, sugar, eggs, and vanilla extract in a large bowl and mixing until combined. Next, the dry ingredients are added - all-purpose flour, cocoa powder, baking powder, baking soda, and salt - stirring until blended together. To finish up the batter you will fold in the sour cream and melted chocolate chips until everything is fully incorporated.
Once your Chocolate Sourcream Pound Cake batter is ready pour it into a greased tube pan. Pour the batter into the prepared pan and bake for 1 hour. Check for doneness by inserting a toothpick into the cake; it should come out clean. Cool the cake in the pan for 30 minutes before turning it out onto a wire rack to cool completely.
