Recipe Notes

-I like Scharffen Berger Chocolate for this recipe. The Semi Sweet Dark Chocolate Baking Bar is my favorite. You may use chocolate chips in this recipe, but I prefer dark chocolate baking bars.-Purchase bakers pans for this recipe. The sides of the pans are straight and will not allow the pans to fit all the way into each other. Read more about pans on the original post. -Put a small amount of frosting (about 1/2 tablespoon) in the middle of the platter before placing the first cake layer on the platter. This will help hold the cake in place.-Use strips of parchment paper under the first layer of cake to help keep the platter clean. When ready to serve, remove the paper and use a damp cloth to clean up any smudges of frosting. -If you don't have time to freeze the cake for the directed amount of time before frosting, wrap the cake in plastic wrap and freeze for about an hour. Remove and frost the bottom layer and rest of cake as directed. Place in fridge or freezer until about an hour before serving. Remove from freezer to let thaw before serving.
