1. Add Boiling Water: Slowly stir in the boiling water. The batter will be thin—this ensures a moist cake.
2. Bake: Pour batter evenly into prepared pans. Bake for 30-35 minutes or until a toothpick comes out clean.
3. Cool: Let cakes cool in the pans for 10 minutes, then transfer to a wire rack to cool completely.

For the Ganache:

1. Heat Cream: In a saucepan, heat heavy cream until it just begins to simmer.
2. Add Chocolate: Pour hot cream over the chopped chocolate. Let sit for 5 minutes.
3. Stir Until Smooth: Add butter and stir until the ganache is smooth and glossy.

Assemble the Cake:

1. Place one cake layer on a serving plate.
2. Spread a layer of ganache over the top.
3. Add the second cake layer and cover the entire cake with ganache.
4. Use an offset spatula for a smooth finish.
