Tips

  • If you are using 9-inch cake pans and want to make a three-layered cake, you will want to double the recipe.
  • Let the ganache cool for 20-30 minutes and the cake cool completely before assembly.
  • Placing the frosted cake in the refrigerator for about 15 minutes helps the ganache set up.
