Ingredients

Sponge Cake:

4 large eggs, separated
¾ cup granulated sugar, divided
¼ cup unsweetened cocoa powder
⅓ cup all-purpose flour
¼ tsp salt
1 tsp vanilla extract

Chocolate Buttercream Filling:

½ cup unsalted butter, softened
1 cup powdered sugar
2 tbsp unsweetened cocoa powder
1 tsp vanilla extract
1–2 tbsp heavy cream, as needed for consistency

Optional Decoration:

Powdered sugar for dusting
Fresh holly or berries
Chocolate shavings or sprigs of rosemary for a pine log effect

Instructions

Preheat your oven: Set to 350°F (175°C). Line a 15×10-inch jelly roll pan with parchment paper and lightly grease it.
Prepare the sponge: In a clean, dry bowl, beat egg whites with a pinch of salt until soft peaks form. Gradually add half the sugar (⅜ cup), continuing to beat until stiff, glossy peaks develop.
Mix yolks: In a separate bowl, whisk egg yolks with the remaining sugar until pale and creamy. Stir in vanilla extract.
Combine dry ingredients: Sift together flour and cocoa powder. Gently fold into egg yolk mixture until smooth.
Fold in egg whites: Carefully fold whipped egg whites into the yolk mixture in three additions, maintaining as much air as possible to keep the sponge light and fluffy.
Bake the sponge: Spread the batter evenly in the prepared pan. Bake 12–15 minutes until the cake springs back lightly when touched. Do not overbake.
Roll the cake: While still warm, invert the cake onto a clean kitchen towel dusted with powdered sugar. Carefully peel off parchment paper. Roll the cake with the towel from the short end. Allow to cool completely.
Prepare the buttercream: Beat butter until creamy, gradually adding powdered sugar and cocoa powder. Mix in vanilla and 1 tbsp heavy cream, adding more if necessary to reach a spreadable consistency.
Assemble the log: Unroll the cooled sponge gently. Spread an even layer of chocolate buttercream, leaving a ½-inch border. Roll the cake back up tightly without the towel.
Decorate: Frost the outside with remaining buttercream. Use a fork to create a bark-like texture. Dust with powdered sugar for a snowy effect. Garnish with holly, berries, or chocolate shavings as desired.
Chill and serve: Refrigerate at least 30 minutes to set before slicing. Serve with hot cocoa or mulled wine for a classic holiday pairing.

Tips for the Perfect Yule Log

Do not overbake: A dry sponge will crack when rolling. Bake just until the cake springs back lightly.
Roll while warm: Rolling immediately helps prevent cracks and keeps the cake pliable.
Buttercream variations: Add a tablespoon of espresso or liqueur for a sophisticated flavor twist.
Decorative touches: Create a snowy forest effect with powdered sugar, meringue mushrooms, or edible glitter.
