Prepare mascarpone cheese - Add the mascarpone to a large mixing bowl (glass or metal) and use a spatula to stir and break up as some brands can be firmer than others. This helps break it up a little to prevent lumps in your whipped cream.
Whip remaining ingredients - Add the cold heavy cream, powdered sugar and vanilla to the mascarpone. You can use an electric hand mixer or a stand mixer with a whisk attachment to whip to stiff peaks. I find it easier to get the right texture with a hand whisk. You’re aiming for a smooth, stiff whipped cream that holds its shape but still looks silky. If it looks split or grainy, it’s been overwhipped.
You can use your whipped cream by blobbing on top of pies with a spoon or a piping bag fitted with a star tip.
