Chocolate lovers, this is the recipe for you! This Dark Chocolate Cake with Chocolate Ganache Frosting is so rich and so decadent it will satisfy even the most die hard chocoholics.
I think we can all agree that it’s not really a celebration unless there is cake. And in my house, chocolate cake is what we serve for the most special of occasions. Of course we have chocolate cake on Valentine’s Day and Christmas. But we also serve it up for anniversaries, birthdays and graduations too. In fact, I was inspired to develop this very recipe because it is the exact cake I would choose for my ‘ultimate’ birthday cake. (how’s that as a not so subtle hint to any family members that may be reading this?)
This cake has a deep and complex chocolate flavor, thanks to the combination of the dark cocoa powder and freshly brewed coffee. And the addition of the buttermilk (or sour cream) makes it so amazingly moist, you can almost serve it without any frosting at all. But topping this delectable cake with rich, creamy chocolate ganache frosting makes it that much better.
How To Make Chocolate Ganache
While it sounds intimidating, making chocolate ganache is actually quite simple. Traditionally, ganache is made with just 2 ingredients: cream and chocolate. Butter is also sometimes added to make ganache that is very shiny and smooth. There are just a few easy steps involved in making ganache:
- Heat cream so it is hot but not boiling.
- Place chopped chocolate into a heat-proof bowl, and pour the cream onto the chocolate. Let sit for a few minutes while the chocolate melts.
- Whisk until smooth and allow to cool.
Why Is It Called Ganache?
The story goes that it comes from a young pastry assistant making the error of pouring hot cream onto chocolate bits. The master chef called him a “ganache” which was an insult at the time (possibly stemming from the French word ganacher, which means to slog). But once the master chef tasted the mistake, he decided to use it to fill and top his cakes. They became wildly popular, and so the chef continued to use the term to describe his delectable chocolate goods.
