Make the Chocolate Ganache: In a saucepan, heat the heavy cream over medium-high heat until it begins to simmer. Do not let it come to a boil.
Place the chocolate chips in a bowl.
Pour the hot cream over the chocolate chips and let it sit for a minute to melt the chocolate.
Stir the mixture until the chocolate is completely melted and the ganache is smooth and glossy.
Allow the ganache to cool to room temperature.
Once the cakes have cooled completely, pour a generous amount of the cooled ganache over the top of the cake, allowing it to drip down the sides.
Use a spatula to spread the ganache over the sides of the cake, covering it completely.
You can decorate the cake as desired.
Allow the ganache to set at room temperature for a couple of hours or in the refrigerator for faster setting.
Your chocolate ganache cake is now ready to be enjoyed! Slice it and serve it to your family and friends for a delicious treat.
