" Perfect" Chocolate Frosting - cooking recipe

Ingredients

6 ounces semisweet chocolate (I use 6 squares baker's semisweet chocolate)
1/2 cup heavy cream
1 cup butter, cut into tablespoon sizes
2 1/2 cups confectioners' sugar, sifted

Preparation

Place a large bowl, filled halfway with ice, in the sink (a bowl that is large enough to hold the pot that you will cook the frosting in).
In a medium size pot over medium low heat, melt chocolate, cream, and butter.
Stirring constantly, cook the mixture until all of the butter and chocolate melts and thickens.
Cook for 5-6 minutes.
DO NOT LET BOIL.
Remove pot from heat.
Whisk in the sifted confectioners' sugar until mixture becomes smooth (approximately 1 minute), then put the pot on top of the bowl of ice (be careful to not allow any ice from the larger bowl to get into pot with the chocolate mixture).
Beat with an electric mixer on low speed for 4-5 minutes until frosting becomes smooth, thick, and fudgy.
Remove from ice.
Spread onto cooled cake layers.
The frosting will thicken as it sets up.
If the frosting gets too hard to spread, put back on LOW heat and stir constantly until you get the spreading consistency desired.
***I have been adding 1 Tbs. of light corn syrup to the initial heavy cream and chocolate mixture to add more glossiness to the frosting.***.
