Holiday Mint Log

This chocolate sponge roll is the foundation of a show-stopping holiday dessert. The batter gets its lift from separated eggs: whites beaten to stiff peaks, yolks whipped with sugar until thick and pale, then the two folded together with cocoa, flour, and just a splash of water. No butter, no oil. That’s what keeps the cake flexible enough to roll.

Timing is everything with a jelly roll. Overbake it by even two minutes and the sponge cracks when you try to roll it. Pull it from the oven when the top springs back from a light touch. Flip it immediately onto a towel dusted with powdered sugar and roll it up while still hot. The cake learns its shape as it cools, so rolling it warm is a must.

Once cooled, unroll gently, fill with your mint cream or frosting of choice, and roll it back up. The powdered sugar towel prevents sticking and adds a light sweetness to the outside.

Chef Tips

• Line the jelly-roll pan with foil AND grease it generously. The sponge is delicate and tears easily.
• Fold the chocolate batter into the egg whites gently with a rubber spatula. Aggressive stirring deflates the whites and gives you a flat, dense cake.
• Roll from the narrow end for a tighter spiral with more visible layers when sliced.
• The cake can be baked and rolled (without filling) a day ahead. Keep it wrapped in the towel at room temperature.

Variations

• Peppermint cream filling: Fold crushed candy canes into whipped cream for a classic holiday pairing.
• Mocha version: Add 1 teaspoon of instant espresso powder to the batter for a coffee-chocolate spin.
• White chocolate ganache: Fill with white chocolate ganache and dust the outside with cocoa powder for a dramatic contrast.
