Ina Garten: Kathleen's Peanut Butter Icing

After making peanut butter cupcakes with a chocolate ganache icing, I started to wonder if it could work the other way, too.  Okay, okay, I was really just thinking how I could make the equivalent of a giant Reese's peanut butter cup.  There's a surprising amount of options when it comes to peanut butter icing.  But Ina's never done me wrong.  In fact, I think she tends to err on the side of fabulous in all the right ways.

Kathleen's Peanut Butter Icing
From Ina Garten

1 cup powdered sugar
1 cup smooth peanut butter
5 tablespoons unsalted butter, at room temperature
¾ teaspoon pure vanilla extract
¼ teaspoon kosher salt
⅓ cup heavy cream

Place the powdered sugar, peanut butter, butter, vanilla, and salt in the bowl of an electric mixer fitted with a paddle attachment. Mix on medium-low speed until creamy, scraping down the bowl with a rubber spatula as you work. Add the cream and beat on high speed until the mixture is light and smooth.
