Hazelnut-Mocha Buche de Noel
Make Ahead Tip: The cake (Steps 1-7) can be made up to 1 month ahead and frozen, towel and all, wrapped in a plastic bag. Thaw at room temperature for at least 1 1/2 hours before unrolling. The frosted cake can be held, loosely covered, in the refrigerator overnight.
Tips: To toast hazelnuts: Spread nuts on a baking sheet and bake at 350°F, stirring once, until fragrant, 7 to 9 minutes.
To bring an egg to room temperature: Either set it out on the counter for 15 minutes or submerge it (in the shell) in a bowl of lukewarm (not hot) water for 5 minutes.
