How do I keep a Bundt cake from sticking?
Go generous with softened butter, then get into every crevice. After that, dust with cocoa powder (not flour) and tap out the excess. Cocoa blends in and keeps the outside chocolatey. Also, let the cake cool 10 to 15 minutes in the pan, then invert. If you leave it too long, it can stick from steam and cooling in place, especially in detailed pans.
Can I make this without coffee?
Yes. Use hot water. Coffee mostly deepens cocoa flavor. You will not taste “coffee” in the finished cake, but hot water still blooms the cocoa and works great.
My cake cracked on top. Is that bad?
Not at all. Bundt cakes often crack because the outside sets before the center finishes rising. The crack becomes the bottom once you flip it, and nobody will ever know.
Can I use Dutch-process cocoa?
Natural cocoa is recommended here because it plays best with baking soda and the recipe’s acidic ingredients. If Dutch-process is all you have, you can use it, but results can vary by brand. For a little extra lift, add 1 teaspoon baking powder and keep the baking soda as written.
How do I know when it is done?
A toothpick should come out with a few moist crumbs, not wet batter. The cake will also spring back lightly when pressed and start to pull just a bit from the edges. If you like a numbers check, the center is typically around 200 to 205°F.
Can I make it ahead for a party?
Absolutely. Bake the cake a day ahead, wrap well, and ganache the day of. The crumb actually improves overnight.
