Very Feathery Fudge Cake

Feathery fudge cake earns its name with a paradox: it’s a deeply chocolatey fudge cake with a remarkably light, airy crumb. The trick is the creaming method (rather than the dump-and-stir approach most modern chocolate cakes use). Butter and sugar get beaten until light and fluffy, eggs blend in, and only then does the melted chocolate join. That long whip introduces enough air to keep the heavy chocolate batter from collapsing into denseness.

Unsweetened chocolate (not cocoa powder) is the right call here. Two and a half ounces melted into the batter delivers a deeper, more complex chocolate flavor than cocoa alone can match, and the cocoa butter in the chocolate keeps the crumb tender. Microwave the chocolate in short bursts and stir between each until smooth. Burnt chocolate ruins the entire cake.

The alternating addition method (flour mixture and water added in turns) is the second classic technique that earns this cake its texture. Adding all the liquid at once shocks the batter and curdles it; alternating keeps the emulsion stable and the crumb tender. End with the dry mixture so the gluten doesn’t overdevelop.

Pro Tips

• Bring all ingredients to room temperature before starting. Cold butter doesn’t cream properly with sugar.
• Tap the filled pans firmly on the counter twice before baking to release air pockets that would create tunnels in the finished cake.
• Test doneness with a toothpick. It should come out clean, not with batter clinging.
• Cool exactly 10 minutes in the pans before turning out. Less and the layers tear; more and they sweat themselves stuck.

Variations

• Frost with chocolate buttercream for a chocolate-on-chocolate finish.
• Use cream cheese frosting for a tangy contrast to the rich chocolate.
• Spread raspberry jam between the layers before frosting for a fruity surprise.
• Add a teaspoon of espresso powder to the batter to deepen the chocolate notes.
