Chop the chocolates into small cubes.

Heat the cream on medium flame and cook until it starts to boil, while stirring all along.

Switch off the flame and pour this over chopped chocolate and let it be for a minute. Then stir well using a spatula.

Add butter and mix it combines well.

Your ganache is ready! It is a superb sauce to use it as cake frostings, toppings on ice creams and brownies. Have fun :)
