Preheat oven to 350°F (175°C).

Coat a bundt pan with baker’s spray or butter and flour it to prevent sticking.

In a large mixing bowl, sift together chocolate cake mix and fudge brownie mix.

Add eggs, water, and oil to the dry ingredients. Whisk for about 2 minutes until smooth.

Pour batter into prepared bundt pan and spread evenly.

Bake for 50-55 minutes. Cake is done when a toothpick comes out clean or with a few crumbs.

Let cake cool in the pan for 5 minutes, then transfer to a cooling rack for at least 30 minutes.

Heat heavy whipping cream in a microwave-safe bowl for about 2 minutes until it just starts to boil.

Add chocolate morsels to hot cream and let sit for 5 minutes, then whisk until smooth.

Once cake is fully cooled, pour ganache over top, using a spatula to spread if needed.
