Step 1

In the bowl of a stand mixer fitted with a whisk attachment or in a large mixing bowl with an electric hand mixer, cream the mascarpone cheese, powdered sugar, and vanilla extract until smooth and creamy.

Step 2

While mixing on low speed, slowly drizzle in the heavy whipping cream until the ingredients are well combined and smooth. Scrape the sides and bottom of the bowl.

Step 3

Increase the mixer speed to medium-high and whip the frosting for a few minutes until medium-stiff peaks form. (The frosting will hold its shape, but still remain soft).
