Philadelphia cream cheese is easy to melt using a microwave or stovetop. To melt the cream cheese in a microwave, place the cheese in a bowl and cover it loosely to avoid splatter. Microwave 20 to 30 seconds at a time, whisking until smooth. To melt cream cheese on the stovetop, place cream cheese into a saucepan over very low heat. Whisk the cream cheese until creamy.
