Marble Pound Cake

This marble pound cake starts with a trick that most recipes skip: browning the butter. Cooking the butter until nutty and amber before chilling it gives the vanilla batter a toasty, caramelized depth that plain melted butter can’t touch.

The cake is lighter than a traditional pound cake. Nonfat yogurt and skim milk keep it moist while using just one whole egg plus two whites (instead of the usual four whole eggs) keeps the crumb tender without being dense. It’s still rich enough to feel indulgent, but not the brick that some pound cakes can be.

The cocoa swirl is made by blooming cocoa powder in hot water, which dissolves any lumps and intensifies the chocolate flavor. That concentrated cocoa paste folds into a portion of the vanilla batter and gets spooned on in pools, then a knife dragged through creates those classic marbled ribbons.

Pro Tips

• Watch the butter carefully while browning. It goes from golden to burnt quickly. Pull it off the heat the moment it smells nutty and you see brown specks on the bottom.
• Freeze the butter-oil mixture until firm but not rock hard. You need it solid enough to cream with the sugar but still pliable.
• Don’t overwork the batter after adding flour. Overmixing develops gluten, which turns a tender pound cake into a tough, chewy one.
• Rap the pan on the counter after marbling. The knife creates air pockets, and those sharp taps settle the batter and prevent holes in the finished cake.

Variations

• Espresso marble cake: Dissolve a tablespoon of instant espresso in the hot water with the cocoa for a mocha-swirled version.
• Orange almond marble: Replace the vanilla extract with orange zest and increase the almond extract for a fragrant, citrusy twist.
