Sweetapolita’s Notes:
•
For the chocolate cake layers, I used Cacao Barry Extra Brute Dutch-process cocoa powder, but you can use any quality dark Dutch-process variety of your choice.
•
I have become rather fond of using vanilla bean paste instead of actual vanilla beans, as it’s convenient and more affordable.
•
When you make the ganache frosting, you’ll notice that it’s a bit jiggly and gelatinous looking as it sets, but as soon as you being to spread it, it becomes smooth, glossy and glorious.
•
Most cake does best at room temperature in terms of staying moist and fresh, but when it comes to building layer cakes, sometimes there’s no choice but to pop it in and out of the fridge a few times to stabilize it.
