HOW TO ASSEMBLE THIS CAKE

• Wrap the cooled cakes and chill in the freezer for a couple of hours.
• Once the frosting is ready, take the cakes out of the freezer. Place the first layer on a flat surface or cake stand (preferably turntable) and put one cup of the frosting on top. Spread with an offset spatula. The excess frosting will hang from the sides. that's okay.
• place the second layer on top of the frosting and repeat the frosting step.
• spread the frosting with a bench scraper until the cake is covered with a thin coat of frosting. Freeze the cake for 15 minutes. This will lock the crumbs in, and the final coating will be clean-looking.
• Decorate the top with piping some frosting. Finish off the decorations with some roasted walnuts.
