If you can't find mascarpone, just replace it with 8 ounces of butter.
Yields 24 cupcakes' worth of frosting
Total time: 5 – 10 minutes
Ingredients: 3 sticks (1-1/2 cups) unsalted butter
8 ounces mascarpone
1/4 cup heavy cream (plus more for thinning, if necessary)
2 cups powdered sugar
Directions: With a hand or stand mixer, beat the butter, mascarpone and heavy cream until it becomes fluffy.
Add the powdered sugar 1/4 cup at a time. Taste the frosting frequently to ensure you're not adding too much.
Once it's all incorporated, increase the mixer speed to high, and beat it until it's fluffy and light. Taste. If it seems heavy, you can add a little extra heavy cream a little at a time to thin it.
Scream "'Merca!" because you now have the perfect American buttercream.
