There is just something about cream cheese frosting that makes all the difference in the world! And, let me tell you, this homemade chocolate cream cheese frosting is to die for!
Gradually increase speed and beat until the frosting is smooth and creamy. If the frosting is too thin, add cornstarch, 1 tablespoon at a time, until the frosting thickens. If the frosting is too thick, add in milk, 1 tablespoon at a time, until the frosting reaches the desired consistency.
Notes
Make sure the butter and cream cheese are thoroughly softened. If the butter and cream cheese are not soft enough to mush, you will have a hard time getting all the ingredients to blend well.
Give the frosting a few minutes to firm up before using it. This will make it easier to pipe.
You can also use a whisk to make this cream cheese frosting. It may take a bit longer, but you will still be able to achieve the silky smooth consistency.
Storage: Store chocolate cream cheese frosting in an airtight container in the refrigerator for up to 3 days or in the freezer for up to 1 month.
