Bûche de Noël (Yule Log cake)

After Katy and I made gingerbread houses for Evan and his friends to decorate, I got to thinking about holiday baking.  I decided it might be fun to try another classic show piece, the yule log -- maybe as a treat to celebrate my parents 35th anniversary when we went down to visit.  Two days later, I got this email from my mom:

Should we make something fabulous for dessert? I've always wanted to try one of these - Buche-de-Noel-with-Marzipan-Mushrooms

Great minds think alike, I guess.  So away we went.  There are lots of recipes on the internet, but some are pretty questionable -- the first cake recipe was a disaster that called for mixing melted chocolate with water, leading to gritty, nasty clumps of seized chocolate in the cake.  (That cake was reincarnated a few days later as a trifle, but that's another story.)  Eventually we cobbled together the necessary components from trusted sources, though, and the result was delicious!  Although I'm not known for, er, pretty food, decorating it was really straightforward too.

Jelly Roll Cake
(from the King Arthur Flour Baker's Companion)

In a stand mixer, whisk until thick and doubled or tripled in volume

1. 4 eggs, at room temperature
2. 3/4 c (5 1/4 oz) granulated sugar

Start the eggs first, then slow add the sugar as the mixer is running.  To quickly get the eggs to room temperature, put them in a bowl and cover with hot tap water for a few minutes.  Mix in

1. 1 t vanilla extract

Sift together

1. 3/4 c (3 oz) all-purpose flour *
2. 3/4 t baking powder
3. 1/4 t salt

Gently whisk the flour mixture into the egg mixture.  If you want a chocolate cake, replace the 3/4 c flour with 1/2 c flour plus 1/4 c cocoa (sifted).  I think the vanilla cake would look more like "wood" under the frosting "bark", but chocolate did work well for me.  Grease a 10" x 15" jelly roll pan, cover the bottom in parchment paper, grease again, and dust with flour (shaking out excess).  This is a very sticky cake -- don't try cutting corners!  Pour in the batter and smooth out to an even layer.  Bake at 400 F until the center is just barely set, about 12 minutes.  Err on the side of underbaking, as an overbaked cake will crack when you try to roll it.
Invert the cake onto a smooth dish towel dusted with powdered sugar (to prevent sticking).  Actually, my cake still stuck, so I'm considering greased wax paper plus powdered sugar next time.  Starting at a short edge, roll up the cake and towel together, and let cool completely on a wire rack.

Rich Chocolate Buttercream
(from The Ultimate Southern Living Cookbook)

Traditional buttercreams require a boiled sugar syrup, but easy buttercreams like this one just whip together butter and powdered sugar.  The double chocolate makes it extra flavorful.

In a double boiler, melt

1. 2 oz unsweetened chocolate
2. 2 oz semisweet chocolate

We used two squares each of Baker's.  You could also probably use the microwave. In a stand mixer, beat until creamy

1. 2 sticks (1 c) butter

Add the melted chocolate and

1. 4 c sifted powdered sugar
2. 1/4 c cocoa, sifted
3. 1/4 c milk
4. 2 t vanilla extract

Beat until creamy and spreadable.

Assembly and Garnish

Once the cake has cooled, unroll and spread evenly with about two-thirds of the frosting.  Leave an inch or two at one of the short ends lightly frosted, as frosting tends to squish forward when the cake is rolled up.  Starting at the other short end, roll the cake back up into a log.

Using a serrated knife, cut off about three inches from one end, at an angle.  (Some people trim both ends, to show off the frosting/cake spiral, but I liked the tree-like look of the crispy cake ends.)  Gently smoosh the cut end up against one side of the roll to make a branch.  Cover the cake in the remaining frosting.  Use the tines of a fork to make a few knots by turning them in a circle, then trace out wood grain by dragging the fork gently along the cake.

We weren't up for making marzipan holly or meringue mushrooms this year, so we used some real holly leaves (washed) with some fresh cranberries that were rolled in sugar while still wet.  (Holly berries are poisonous, so just in case, we removed the leaves after taking the picture.)  Use a strainer to dust a little powdered sugar over the top to create the snow effect, if desired.
