Good chocolate cake may be the perfect dessert and this one does not disappoint. It deserves to be a standard in every family recipe collection.

It is the best plain chocolate frosted cake that I have ever eaten. The chocolate Italian buttercream frosting can be a bit of a challenge, especially in a hot kitchen.

Dark Chocolate Chips, to melt and dip the biscotti

Dark chocolate at least 50% cocoa is best for this recipe. 

However, it is well, well worth the effort to master this skill. It really is the best chocolate frosting ever; so luscious and so, so silky smooth.

The detailed recipe gives you step by step instructions on how to make Italian chocolate buttercream frosting like an expert.

Chocolate Buttercream Cake

Prep Time: 1 hour
Cook Time: 40 minutes
Total Time: 1 hour 40 minutes

The best chocolate scratch cake ever layered and covered in melt-in-your-mouth luscious Italian chocolate buttercream frosting.

Ingredients

For the Chocolate Cake

  • 2 cups sugar
  • 2 cups all purpose flour
  • 3/4 cup cocoa
  • 2 tsp. baking powder
  • 1 tsp baking soda
  • 1/2 tsp salt
  • 2 eggs
  • 1 cup soured milk, add a tablespoon of lemon juice to sour the milk
  • 1 cup black coffee
  • 1/2 cup vegetable oil
  • 1 tsp vanilla extract

For the chocolate buttercream frosting

  • 1 pound chocolate, at least 50% cocoa, chopped in small pieces
  • ½ cup butter
  • 2 cups sugar
  • 2/3 cup water
  • 6 egg whites at room temperature
  • ¼ tsp cream of tartar
  • 2 tsp vanilla extract
  • Pinch salt
  • 2 cups 1 pound softened unsalted butter

For the Ganache Drizzle (optional)

  • 1/3 cup chocolate chips
  • 1 1/2 tbsp whipping cream

Instructions

For the chocolate cake

  1. Combine all ingredients in a mixing bowl and beat with electric mixer for 2 minutes.
  2. Pour into 2 greased and floured 8 or 9 inch cake pans. Bake at 350 degrees F for 35-40 minutes or until toothpick inserted in the center comes out clean.
  3. Cool in the pans for 5 minutes, then remove from pans and cool completely on a wire rack.

To make the frosting

  1. Combine the chocolate and 1/2 cup of butter and melt (but do not over heat) in a double boiler. Set aside to cool to room temperature.
  2. Combine the sugar and water in a small saucepan and bring to a boil.
  3. Continue to boil over medium heat without stirring until the mixture reaches 240 degrees on a candy thermometer.
  4. Meanwhile beat together the egg whites, cream of tartar, vanilla extract and salt to stiff peaks.
  5. Slowly pour in the sugar syrup in a thin stream, hitting the side of the bowl and not the beaters. Continue beating the frosting for 10-15 minutes until the meringue is completely cool.
  6. When completely cool, slowly begin to add the butter a few tablespoons at a time. Beat until smooth after each addition.
  7. Add the melted chocolate to the meringue mixture in about 4 additions and beat well after each addition.
  8. Continue beating until frosting reaches a spreadable consistency. This may take 15 minutes or so and you may have to chill the frosting for several minutes before beating it again to get it to stiffen. Alternatively, you can place the frosting bowl in an ice bath while continuing to beat constantly until the icing stiffens sufficiently.

To construct the cake

  1. Split the cake layers in half, horizontally, making 4 layers in total. Fill layers with frosting and spread over the entire cake. Garnish with chocolate ganache or chocolate curls if desired.

Chocolate Ganache

  1. It's best to add the drizzle when the frosting has been chilled on the cake for an hour or so.
  2. In a double boiler, combine and melt the chocolate and cream but be careful not to overheat it.
  3. Spoon the ganache into a Ziploc bag and snip off a corner with sharp scissors. Use the bag to drizzle the chocolate in continuous circular motions all over the surface of the cake.

Notes

Additional time is needed to cool the cake. About 2 hours.
