If you've never worked with mascarpone before, it's similar in texture to cream cheese, just slightly softer. Like cream cheese, it's easiest to beat this cheese with an electric mixer to ensure it doesn't have any lumps in it. However, if you don't have a stand mixer, you can do it by hand. Just make sure to mix together the mascarpone and the granulated sugar first until the mascarpone cheese has loosened in consistency, then add in the egg.
The mascarpone can be replaced with an equal amount of cream cheese, if desired.
