Instructions
Prepare Cake
Preheat oven to 350F and set aside a greased 9.5-inch bundt pan.
In a large bowl, whisk together all-purpose flour, sugar, cocoa powder, baking soda, salt, and espresso powder (if using).
Add water, oil, vinegar, and vanilla and mix until smooth.
Transfer batter to prepared baking pan and bake until an inserted toothpick comes out clean, about 40 to 45 minutes. Cool in the pan for 10 minutes, then transfer to a wire rack to cool completely.
Prepare Ganache
Place chocolate in a heat-safe bowl and set aside.
Bring whipping cream to a boil over medium high heat. Pour directly over chocolate and let it sit undisturbed for 5 minutes. Gently whisk until completely smooth.
If the ganache feels too runny, refrigerate for a few minutes until it thickens. If the ganache feels too thick, add a splash of heavy cream and whisk until smooth. Drizzle ganache over cooled cake.
