One of my coworkers had a birthday last week, which means I did some baking. This coworker requested chocolate cupcakes, so I knew I’d turn to the Joy of Cooking for the cupcake recipe. But the frosting was where I wanted to have some fun.
My mom always made buttercream frosting for cupcakes, but I’ve always found most frosting to be too sweet for my taste. I remembered this coworker being fond of peanut butter, so I looked around for a recipe online for peanut butter frosting and came across this one.
The original recipe called for creamy peanut butter, but I only ever buy crunchy, so I used that. The frosting held up well and complemented the cupcakes nicely. It’s definitely a nice alternative to the more common options.
1 cup confectioners’ sugar
1 cup crunchy peanut butter
5 tablespoons unsalted butter, at room temperature
3/4 teaspoon pure vanilla extract
1/4 teaspoon kosher salt
1/3 cup heavy cream
Place the confectioners’ 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.
