Have the peanut butter and Earth Balance at room temperature, and the cream cheese cold. Place the ingredients in a bowl and mix with a wisk or with a handheld or stand mixer until everything's combined.
Add the sugar ½ cup at a time, beating in well after each addition. I use less sugar than most peanut butter frosting recipes would, but if you want a stiffer frosting add more confectioners sugar.
Place the frosting in the refrigerator for at least 30 minutes before frosting.
