Prepare bundt pan by spraying lightly with a nonstick spray and then dusting with cocoa powder. Invert pan and tap out any excess cocoa powder.I first spray the entire pan then sprinkle in the cocoa powder. Shake the pan to help distribute the cocoa powder. I just cover the lower half of the pan with the powder.
1-2 tablespoons cocoa powder
Combine melted butter and cocoa powder together in a bowl.
1 cup butter, 1 cup unsweetened cocoa powder
In a separate bowl, combine flour, sugar, baking soda and salt.
2 ½ cups flour, 2 cups sugar, 2 teaspoons baking soda, ¾ teaspoon salt
In a smaller bowl, combine sour cream, eggs, oil, water and vanilla.
¾ cup sour cream, 3 eggs, ¼ cup oil, ½ cup warm water, 2 teaspoons vanilla
Stir in butter and cocoa mixture to the egg mixture.
Add the wet ingredients to the dry ingredients. Stir gently together with a silicone spatula or a wooden spoon until everything is combined.
Pour or scoop the batter into the prepared bundt pan. Try to level the top of the batter.
Bake in preheated 350°F oven for 45-50 minutes or until baked through.
Remove from oven and allow cake to cool for 10 minutes. Gently use a butter knife t loosen any sides of the cake that may be stuck to the cake pan. Invert cake pan and shake gently to remove cake from pan. Allow cake to cool on a baking rack.
Glaze
Heat heavy cream over medium heat. Heat just until it comes to a boil. Remove from heat and pour oven chocolate chips. Do not stir! Allow the mixture to sit for 5 minutes to melt the chocolate. Stir well until all the chocolate and cream are combined.
½ cup heavy cream, ½ cup chocolate chips
Pour over the cake. Allow the cake to sit for about 30 minutes before serving. This will allow the glaze to harden just slightly.
Notes
No need to use an electric mixer for this cake. Everything can be mixed together by hand using a heavy silicone spatula or wooden spoon.
Make certain the butter and unsweetened are fully combined and no lumps are formed.
Test the cake with a toothpick or wooden skewer. If the toothpick comes out dry or just a few moist crumbs, the cake is done. If the toothpick is covered with batter or wet crumbs, cook for a few minutes longer.
Use a good quality bundt pan for the best results and easy release. If your bundt pan is scratched, you might have a tough time getting the cake out of the pan.
Don't add the chocolate glaze until the cake is fully cool.
