- Level the Cakes:
If necessary, level the tops of the cooled cakes with a serrated knife to ensure even layers. - Frost the Cake:
Place one cake layer on a serving plate or cake stand. Spread a generous amount of buttercream on top, then place the second cake layer on top. Frost the top and sides of the cake with the remaining buttercream. - Decorate:
Decorate the cake with chocolate shavings, sprinkles, or any other toppings of your choice.
