• Preheat the oven to 400 degrees F (200 degrees C). Brush a little melted butter over a 13x18-inch rimmed sheet pan. Line pan with parchment paper and brush remaining melted butter on top.
• Combine cocoa powder, salt, and flour together in a bowl; whisk or sift to break up clumps.
• Place eggs in the clean bowl of your stand mixer. Add sugar and whip until fluffy, thick, and very light in color. Add 1/2 of the cocoa powder mixture and vanilla extract; mix on low speed for a few seconds. Beat in remaining cocoa mixture on low for a few seconds. Switch to high speed; stop once mixture is moistened but not fully blended. Pull off the whisk attachment and whisk batter with it until evenly blended.
• Pour batter onto the prepared sheet pan and spread out with a spatula, leaving some room around the edges. Tap pan on the counter to knock out the large bubbles.
• Bake in the preheated oven until top is dry and edges start to pull away from the sides, 8 to 10 minutes.
• Dust a clean kitchen towel with enough powdered sugar to cover an area slightly larger than the sponge cake. Remove cake from the oven. Run a knife around the edges of the pan. Sprinkle some powdered sugar over the top. Run a spatula under the parchment paper to make sure it's not stuck to the pan.
• Quickly flip pan on top of the sugared area to invert the cake. Remove parchment paper and dust cake with more powdered sugar. Gently roll cake up inside the towel; allow to cool for 15 minutes.
• Unroll cake and dollop buttercream on top, reserving some for later. Spread frosting to the edges. Roll cake up over the frosting, using the towel to lift it if needed. Sprinkle more powdered sugar on top. Wrap log in plastic wrap. Refrigerate until firm, about 2 hours.
• Combine chocolate chips and hot cream in a bowl. Let sit for 1 minute. Whisk until chocolate melts.
• Make an angled cut 3 inches from one end of the log. Place log on a parchment-lined sheet pan. Apply some buttercream to the angled slice and attach it to one side. Spread a layer of ganache all over the cake, except for the swirls. Refrigerate for 15 minutes to firm up ganache.
• Carve lines into the ganache using the tip of a knife to create the appearance of tree bark. Refrigerate until completely chilled before serving. Dust with cocoa powder and powdered sugar.

CHOCOLATE AND COFFEE YULE LOG

Steps:

• For Kahlua simple syrup:
• Add the granulated sugar and water to a small saucepan over medium heat and whisk until the sugar is completely dissolved. Bring to a boil, then remove from the heat and add the liqueur.
• Stir to combine and allow syrup to cool completely.
• For Biscuit Roulade:
• Preheat oven to 375 degrees F. Butter and flour a 15 by 10 by 1-inch jelly roll pan. Line the bottom with parchment paper and butter and flour the paper.
• Combine the flour, baking powder, and cocoa in a small mixing bowl, set aside.
• Beat egg yolks in a medium mixing bowl with an electric mixer on high speed until thick and lemon colored, about 5 minutes. Gradually add 1/2 cup of the sugar, beating on high speed until the sugar is dissolved. Thoroughly wash and dry the beaters. Beat egg whites in a large mixing bowl with an electric mixer on medium speed until soft peaks form, about 5 minutes. Slowly add the remaining 1/2 cup of sugar, beating on medium speed until stiff peaks form.
• Carefully fold the egg yolk mixture into the egg whites, using a rubber spatula. Once all of the egg yolk mixture has been incorporated, sprinkle the flour mixture over the egg mixture and fold in gently, just to combine.
• Spread the batter evenly into the prepared jelly roll pan. Bake until the cake springs back when lightly touched near the center, about 12 to 15 minutes.
• Lay out a clean, thin cotton kitchen towel on a work surface; dust the top with confectioners' sugar and set aside.
• Immediately after removing the cake from the oven, loosen the edges of the cake from the pan using a knife.
• Turn cake out onto the sugared kitchen towel, parchment paper side up. Carefully pull off the parchment paper.
• Fold towel over the longest side of the cake and roll up the cake with the towel inside.
• Cool on a rack with the seam side down.
• For Coffee Buttercream:
• Bring 1/2 cup of water to a boil in a small saucepan over high heat. Remove from heat and add the coffee grinds; allow to steep for 5 minutes. Strain through a coffee filter into a small bowl and set the coffee concentrate aside.
• Mix the remaining 1/2 cup of water and sugar in a heavy 2-quart saucepan over medium-high heat. Clip a candy thermometer to the pan and heat to 240 degrees F, soft-ball stage, 18 to 20 minutes. Keep the edge of the saucepan clean by brushing it with a pastry brush moistened with water, as needed.
• Once the temperature reaches 240 degrees F, remove the candy thermometer and remove the saucepan from the heat.
• Beat the egg whites in a large mixing bowl with an electric mixer on medium speed until soft peaks form, about 5 minutes. Gradually pour the hot mixture, in a thin stream, over the whites while continuing to beat for 2 to 3 minutes. Scrape the sides of the bowl as needed and continue to beat until a meringue forms.
• Add the butter all at once, and beat on medium speed until incorporated. Increase speed to high and continue beating until smooth and shiny, about 8 to 10 minutes. Add the vanilla extract and coffee concentrate and mix for 1 minute until combined. Set aside.

YULE LOG

Steps:

• Separate the 5 yolks from whites, obviously into two separate bowls. Place egg whites in a small mixing bowl and let the whites stand at room temperature for 30 minutes or more.
• Grease a baking pan, then line the pan with parchment paper. Finally, grease the parchment paper. I use Crisco (a vegetable shortening) as the grease, but you could use butter, margarine or even (yuck) animal lard. This recipe presumes a 15 inch by 10 inch by 1/2 inch deep pan, but you can use a pan that is larger in any dimension(s), and just crimp the parchment paper at the proper dimensions.
• In a large mixing bowl, beat the egg yolks on high until they are light and fluffy. Gradually add 1/2 cup sugar, beating for a few minutes, until thick and lemon-colored.
• In a dry bowl, combine the 1/2 cup cake flour, 1/4 cup baking cocoa (powdered cocoa) & 1/4 teaspoon salt with a whisk.
• Slowly add the flour mixture to the egg yolk mixture and blend on medium, until well mixed.
• Beat egg whites (in a separate clean bowl) on medium until foamy. Add the 1/2 teaspoon of cream of tartar. Continue to beat until soft peaks form. then, slowly add the remaining 1/2 cup of sugar, beating on high until stiff peaks form.
• Slowly and gently fold the egg whites into the chocolate flour mixture, until no streaks remain.
• Gently spread the batter evenly in the prepared pan.
• Bake in the preheated oven at 350° for about 12 minutes or until cake springs back (do not over bake; certainly not more than 15 minutes. It is better to under bake rather than over bake!).
• Cool the cake for 5 minutes, then invert onto a linen towel dusted with confectioners' sugar (or another piece of parchment paper, dusted with the powdered sugar). Peel off parchment paper.
• Roll the cake up in the towel or paper, starting with a short side. Then let it cool on a wire rack. The cake portion is now done! If you need to take a break, put the cake in a sealed container or plastic bag.
• MAKING THE FILLING. Alternatives: [1] If you are in a hurry or want a white filling, you could instead just use a topping like "Cool Whip"; but it would need to be served within hours, before the Cool Whip melted and went flat. [2] Another white filling can be made by whipping 1 cup of whipping cream until it is light and fluffy, then beating in 1/2 cup powdered sugar. Obviously, this requires the cake to be kept refrigerated, except when serving it. [3] For a white, vanilla buttercream filling, see the "white buttercream filling recipe" at the bottom of this page; [4] For a chocolate buttercream filling, see the "chocolate buttercream filling recipe" at the bottom of this page; [5] For a mocha (coffee) filling, add 1 tablespoon of instant coffee granules to any of these above.
• Whip 4 egg whites in a clean dry mixing bowl until fluffy peaks form.
• Add the 1 and a half cups of powdered (icing or confectioner's sugar) to the mixer. Then add 1/4 teaspoon vanilla extract and 1/4 cup powdered baking cocoa. Whip briefly, but to a uniform color.
• Unroll the cake! If you want to make two shorter cakes, simply cut the cake in half before unrolling it. The advantage of this is, you can make one with chocolate filling, the other with a white filling, or mocha, etc.
• Spread it about at least 1/4 inch thick, up to a maximum of 1/2 inch thick.
• Gently and loosely roll the cake, not squeezing! You don't want to squeeze out the filling. Again, the chocolate filling is on the left, the white buttercream (or whipped cream) is on the right. Now, while the white icing looks better, the chocolate tastes much better -- in my opinion.
• MAKING THE ICING / FROSTING: Alternatives: If you are in a hurry, you can use a pre-made, store-bought can of chocolate frosting / icing, instead.
• In a mixing bowl add 1.5 cups confectioners' sugar (also called powdered sugar and in the UK, icing sugar) , 2 egg whites, 3 tablespoons melted butter, 1 teaspoon lemon juice & 1/4 teaspoon vanilla, then whip it up in your electric mixer.
• Add the cocoa, and mix with the mixer until uniform.
• Gently slurp the icing on the cake (top and ends). Note: the log in the photo appears short because I cut the roll in half to make two short logs, rather than one long log.
• I use a pastry blending knife to make the lines in the icing to look like a log! I just drag the front of it across the log. Of course, you can buy special decorating tools for this, also.
• You can also dust it with powdered sugar, to simulate snow!
