Description
This classic chocolate yule log cake is a tender chocolate sponge cake filled with mascarpone whipped cream and covered with whipped chocolate ganache. It’s delicious, festive, and made completely from scratch using authentic French baking techniques.
Ingredients
For the Chocolate Sponge Cake:
3/4 cup (98g) all-purpose flour
1/3 cup (38g) Dutch process cocoa powder
1 tsp baking powder
1/2 tsp salt
4 large eggs, separated
3/4 cup (155g) granulated sugar, divided
5 tbsp (72g) sour cream
1/4 cup unsalted butter, melted and slightly cooled
1 tsp vanilla extract
For the Mascarpone Whipped Cream Filling:
1 1/4 cups (300ml) heavy whipping cream, cold
3/4 cup (86g) powdered sugar
1 tsp vanilla extract
1/8 tsp salt
8 oz (226g) mascarpone cheese, softened but chilled
For the Whipped Chocolate Ganache:
8 oz semi-sweet chocolate, finely chopped
1 cup heavy whipping cream
For Decoration (Optional):
Fresh cranberries and rosemary sprigs
Powdered sugar for dusting
Instructions
1. Preheat oven to 350°F (175°C). Line a 17×12-inch jelly roll pan with parchment paper, extending 1 inch over all sides.
2. Sift together flour, cocoa powder, baking powder, and salt in a medium bowl. Set aside.
3. In a large bowl, whisk egg yolks with 1/2 cup sugar until pale and thick, about 2 minutes. Add sour cream, melted butter, and vanilla. Whisk smooth. Fold in dry ingredients until just combined.
4. In a clean mixer bowl, beat egg whites to soft peaks. Gradually add remaining 1/4 cup sugar, beating to stiff, glossy peaks, 4-5 minutes total.
5. Fold 1/3 of egg whites into chocolate batter to lighten. Gently fold in remaining whites until just combined (some white streaks are fine).
6. Spread batter evenly in prepared pan. Bake 10-12 minutes until top springs back and toothpick comes out clean.
7. Immediately lift cake out using parchment overhang. Starting at short end, roll up cake with parchment inside. Unroll and re-roll 3-4 times during cooling (at 5, 10, and 20-minute intervals). Cool completely, about 60-90 minutes.
8. For filling: Whip cold cream with powdered sugar, vanilla, and salt to soft peaks. Add mascarpone and beat to stiff peaks, about 1 minute. Don’t overbeat.
9. Carefully unroll cooled cake. Spread filling evenly, leaving 1/2-inch border. Re-roll without parchment. Wrap in plastic wrap, seam side down. Refrigerate 2-3 hours.
10. For ganache: Place chopped chocolate in bowl. Heat cream until just boiling, pour over chocolate. Let sit 4 minutes, then whisk smooth. Cool to room temperature, about 60 minutes.
11. Transfer cooled ganache to mixer bowl and whip on high 3-5 minutes until lightened in color and spreadable.
12. Cut 2-3 inch piece from one end at diagonal. Attach to side with ganache to create “branch.” Spread ganache over entire log, leaving ends exposed. Drag fork lengthwise to create bark texture.
13. Add sugared cranberries, rosemary sprigs, and dust with powdered sugar. Refrigerate until 30 minutes before serving.
Notes
Dutch Process Cocoa: The recipe originally listed Hershey’s Special Dark cocoa powder. You can use any Dutch process cocoa powder for richer flavor than natural cocoa.
Mascarpone Temperature: Use mascarpone when still cool but softened, so it incorporates without chunks but doesn’t get too warm and soft.
Preventing Cracks: The periodic unrolling during cooling is the secret to preventing cracks. Don’t skip this step!
Make-Ahead: The fully assembled cake can be made up to 2 days before serving. Add final decorative touches (powdered sugar, fresh rosemary) right before serving.
Storage: Refrigerate covered for up to 4 days. Freeze wrapped tightly for up to 2 months.
Variations: For vanilla yule log, omit cocoa and increase flour to 1 cup (130g). Add extra 1/2 tsp vanilla extract.
Sugared Cranberries: Simmer 1/2 cup sugar and 1/2 cup water for 5 minutes. Cool 10 minutes. Dip cranberries and rosemary in sugar water, then roll in 1/2 cup sugar. Let dry before decorating.
