Common Questions
Can I make this without coffee?
Yes. Swap the hot coffee for hot water. Coffee does not make it taste like coffee, it just makes the chocolate taste louder.
Why cake flour instead of all purpose flour?
Cake flour has less protein, so the cake bakes up lighter and more tender. If you only have all purpose flour, you can still make this cake. It will be slightly less airy, but still great.
Can I substitute for buttermilk?
If you do not have buttermilk, mix 1 tablespoon lemon juice or white vinegar with enough milk to make 1 cup. Let it sit 5 minutes, then use it. The texture will be close.
Can I use natural cocoa powder instead of Dutch process?
You can, but expect a slightly different flavor and lift. This recipe is written for Dutch process cocoa. If you use natural cocoa, it can react differently with the leaveners and buttermilk. If you want to keep it simple, stick with Dutch.
How do I keep the cake from doming or cracking?
Do not overmix, and bake on the center rack. If your oven runs hot, drop the temperature by 25°F. You can also use cake strips for extra-even layers.
My ganache looks grainy. Can I fix it?
Usually, yes. Warm it gently (microwave in 10-second bursts, stirring) until smooth. If it separated, whisk in 1 to 2 teaspoons warm cream to bring it back together.
My ganache seized. What now?
If even a tiny bit of water got in, chocolate can seize and turn stiff. Add 1 teaspoon warm cream at a time and stir patiently until it loosens and turns glossy again. Also make sure your bowl and spatula are totally dry.
Can I make cupcakes with this batter?
Yes. Fill liners about 2/3 full and bake at 350°F for 16 to 20 minutes, until a toothpick comes out with a few moist crumbs.
Can I bake the layers ahead?
Yes. Bake, cool completely, then wrap each layer tightly in plastic wrap. Keep at room temp for 1 day, or freeze up to 2 months. Thaw wrapped layers overnight in the fridge, then bring to room temp before frosting.
