Instructions
- Prepare Sugared Cranberries and Rosemary: Place fresh cranberries and rosemary sprigs in a heatproof bowl. In a saucepan over medium heat, dissolve 3/4 cup (150g) sugar into water by simmering; cool 5 minutes. Pour syrup over cranberries and rosemary, stir, cover, and let sit 15 minutes. Transfer cranberries and rosemary to a parchment-lined baking sheet using a slotted spoon; dry uncovered 1 hour. Toss them in remaining 1/2 cup (100g) sugar, then dry uncovered for at least 1 hour or refrigerate up to 3 days.
- Preheat and Prepare Baking Pan: Preheat oven to 350°F (177°C). Spray a 12×17-inch baking pan with nonstick spray and line with parchment paper, greasing the parchment as well to ensure nonstick surfaces for the cake roll.
- Sift Dry Cake Ingredients: Whisk together cake flour, cocoa powder, baking powder, and salt in a medium bowl; set aside.
- Whip Egg Whites: Using a mixer, beat egg whites with 1/2 cup (100g) sugar on high speed until stiff peaks form (about 4-5 minutes). Transfer to another bowl.
- Beat Egg Yolks: In the same mixing bowl, combine egg yolks with remaining sugar, oil, and vanilla extract. Beat until thick and light, about 3-4 minutes on high speed.
- Fold Batter: Fold half of the whipped egg whites into the yolk mixture with low-speed beating for 10 seconds. Repeat with remaining egg whites. Then fold in half of the flour mixture gently; repeat with remaining flour mixture. Avoid overmixing to keep batter light.
- Bake Cake: Spread batter evenly in prepared pan; gently tap pan on counter to remove air bubbles. Bake 15-16 minutes until cake springs back lightly to touch. Avoid overbaking to prevent cracking.
- Roll Cake: While baking, prepare a large piece of parchment paper or kitchen towel dusted with cocoa powder. Invert warm cake onto it, peel off bottom parchment, and carefully roll the cake up with the parchment or towel starting from narrow end. Let cool completely rolled, refrigerate 3 hours to overnight to set.
- Make Meringue Mushrooms: Preheat oven to 200°F (93°C). Beat egg white, cream of tartar, and salt until foamy (~2 minutes). Slowly add sugar while mixing at high speed until stiff and glossy peaks form (~2 minutes). Pipe quarter-sized circles for mushroom caps and 1-inch tall cones for stems onto parchment-lined baking sheet. Smooth peaks with a moistened finger; dust caps with cocoa powder if desired. Bake 2 hours without opening oven, turn off oven and rest 20 minutes inside. Cool completely.
- Assemble Mushrooms: Melt 1 ounce chopped chocolate in double boiler or microwave in short bursts, stir until smooth and cool slightly. Dip bottom center of mushroom caps in chocolate to attach stems. Let chocolate set about 1 hour.
- Prepare Whipped Cream Filling: Whip heavy cream with Frangelico, confectioners’ sugar, and cocoa powder on medium-high speed until medium to stiff peaks form (2-3 minutes).
- Fill and Roll Cake: Remove cake from refrigerator and let warm slightly. Gently unroll cake, spread whipped cream evenly leaving 1/2 inch border. Sprinkle chopped hazelnuts. Slowly reroll cake without parchment. Dust exterior with cocoa powder if moist. Refrigerate uncovered at least 30 minutes up to 2 days.
- Make Ganache: Heat heavy cream until just simmering. Pour over chopped chocolate, wait 2-3 minutes, then stir until smooth. Refrigerate uncovered 30 minutes to 1 hour until thickened.
- Finish Cake: Remove cake from refrigerator. Cut a 3-4 inch diagonal piece from one end to serve as a branch. Place slice against the log. Pour and spread ganache over top and sides of cake; create bark texture with a fork. Wipe any ganache drips from plate.
- Decorate and Serve: Arrange meringue mushrooms, sugared cranberries with rosemary sprigs, and dust with confectioners’ sugar on and around the cake. Store leftover cake covered in refrigerator up to 3 days.

- Watch the baking times carefully to avoid drying or cracking the cake sponge.
- Use a kitchen towel dusted with cocoa powder for rolling if you want to reduce risk of cracking.
