Beat sugar, butter and vanilla in a mixer on medium speed until light and fluffy. Beat in egg until incorporated.

In a separate bowl, sift together cake flour, cocoa, soda and salt. Add dry ingredients to butter mixture and mix until thoroughly incorporated. Add the buttermilk and continue to mix until the cake batter is smooth and all the ingredients are combined.

Gently spread the batter onto the parchment lined jellyroll pan.

Bake 20-25 minutes or until toothpick inserted in cake center comes out clean. Remove cake pans from oven and let cool to room temperature.

In a mixing bowl with the beater attachment, whip the cream until soft peaks form. With the mixer running, add the sugar, vanilla extract and Chambord. Continue to beat the cream mixture until stiff peaks form.

Spread the whipped cream on top of the baked chocolate cake in the pan.

Using the parchment paper as your guide, gently roll the cake into a log shape. Gently pull the parchment away as you go. Gently place the rolled cake on a piece of fresh parchment.

To make the frosting, place the chocolate in a large bowl. Heat the cream, sugar and butter in a saucepan over medium heat. Stir until the sugar is dissolved and the butter is melted. Pour the hot cream mixture over the chocolate.

Let the chocolate stand for 3 minutes, then stir the mixture until the chocolate is velvety and smooth. Allow the ganache to cool to room temperature then cover and refrigerate until ready to use. Note: the ganache should not be too thick or it will be difficult to frost the cake. If the ganache becomes too thick, add additional heavy cream until it is thinner in consistency.

Frost the Yule log with the chocolate ganache frosting. Using the handle end of a spoon, gently score the Yule log to create the texture of "tree bark." With a knife on the diagonal, cut off 3-4" piece off each end of the Yule log. These pieces will serve as "branches." Place each end piece on the side of the Yule log.

Gently place the frosted Yule log on a silver platter. Using a sifter, gently dust the top of the Yule log with powdered sugar. Place whole raspberries around the Yule log. Garnish the tray with some holly.
