Instructions
 

Make The Chocolate Butter & Mascarpone Filling

  • Cream together the butter, powdered sugar, vanilla extract, cocoa powder, and salt.
    1 ⅔ cups powdered sugar, ½ cup unsalted butter, 1 tablespoon vanilla extract, 1 ½ tablespoons unsweetened cocoa powder, 1 pinch salt
  • Fold in the mascarpone cheese & set aside.
    ⅓ cup mascarpone cheese

Bake The Chocolate Sponge Cake

  • Preheat oven to 400 degress F.
  • Prepare a 13" x 18" jelly roll pan by brushing the pan with the melted butter and lining it with parchment paper before brushing the remaining butter on top.
    2 tablespoons melted butter
  • In a medium bowl, sift together flour, cocoa powder, and salt.
    ½ cup unsweetened cocoa powder, 2 tablespoons all-purpose flour, ½ teaspoon kosher salt
  • In a large bowl, whip together eggs and sugar until the mixture becomes lighter in color.
    5 large eggs, ⅔ cup white sugar
  • Add vanilla extract and slowly whisk 1/3 of the dry flour & cocoa mixture.
    ½ teaspoon vanilla
  • Add another 1/3 of the mixture, whisk slowly, and add the final 1/3 until just mixed. Do not overmix.
  • Pour batter into prepared baking pan and spread evenly with a spatula.
  • Bake for 8 - 10 minutes until the top is dry and the edges begin to lift.

Roll The Cake

  • While the cake bakes, lay a large, clean kitchen towel on your counter. This will be what you use to roll the warm cake.
  • Using a sifter, dust the cloth with powdered sugar.
    2 tablespoons powdered sugar
  • When the cake is finished baking, invert it onto the powdered towel.
  • Remove the parchment paper and dust the bottom of the cake with more powdered sugar.
  • While still warm, roll up the towel and cake together like a sushi roll.
  • Allow the rolled up towel & cake to cool for 15 minutes.

Fill The Cake

  • Carefully unroll the cake and cover the top with the butter & mascarpone frosting.
  • Re-roll just the cake, leaving the towel on the counter.
  • Dust the cake with more powdered sugar.
  • Wrap the full cake in plastic wrap, like a chub of sausage.
  • Place your cake log into the fridge to cool for 2 hours.

Make Chocolate Ganache

  • After 2 hours, heat heavy cream to near-boiling.
    1 cup heavy cream
  • Pour chocolate chips into a large bowl.
    8 ounces dark chocolate chips
  • Pour near-boiling heavy cream over the chocolate chips, let sit for 1 minute, and whisk until smooth.

Design Your Yule Log

  • Cut your yule log in any shape you'd like. You can keep it whole as one log, or cut off a corner and attach it to the side, as a new limb that has been cut off. We like to cut the ends off to clean up the spiral pattern of the log.
  • Spread the ganache over the top of your shaped log and refrigerate to harden the ganache.
  • Use a knife to carve the ganache to look like the bark of a tree.
  • Move to a serving plate and decorate with your favorite holiday treats.
