In the bowl of a stand mixer, beat the eggs and sugar on high speed until it double in size.
Gently fold in the flour.
If you need more details on how to make this cake, check out my recipe for the perfect genoise! Poor the batter onto a baking sheet with a silicone mat (or a buttered and floured parchment paper).
Bake at 350F (180C) for 8 to 10 minutes. It should be a little sticky to the touch but a toothpick should come out clean.
Sprinkle some icing sugar on a clean tea towel. Place the sponge cake on the towel and roll in.
Let it cool down.
Then, make the chocolate ganache.
In a sauce pan, bring the whipping cream to a boil.
Add the chocolate in a large bowl then poor the hot cream on top. Cover and let it sit for a couple of minutes.
Stir well, until the mixture is smooth and shiny.
Unroll the cake. Spread 3/4 of the chocolate ganache on the cake. Then roll it down.
You can leave it like that and cover the Christmas Log with the rest of the ganache.
Or you could cut a piece of cake in a diagonal and place it on the side of the log and then cover with the rest of the ganache.
Using a fork, carve the chocolate ganache to make it look like an actual piece of wood!
Decorate with a few meringue mushroom!
