Baker’s notes

Distinct swirls, one tender cake

A good marble cake should taste clearly of vanilla and chocolate while both batters retain the same soft texture.

Swirl with restraint

Layer vanilla and chocolate batter, then draw a knife or skewer through them only a few times. Overworking the swirl muddies the pattern instead of creating ribbons.

Keep ingredients aligned

Room-temperature ingredients combine more evenly. Mix just until smooth and avoid overworking the batter after the flour is added.

Butter or oil

Butter delivers the richest flavor. Oil can be substituted for additional moisture, but the finished cake will lose some of its buttery character.

Storage

Store airtight for up to three days at room temperature or five days refrigerated. Well-wrapped cake can be frozen for up to three months and thawed at room temperature.
