Difficulty: Easy
Ingredients
1/2 cup (1 stick) butter, softened
1 cup packed dark brown sugar
1/3 cup heavy cream, plus more as necessary
1 tablespoon pure vanilla extract
1 16-ounce box confectioner’s sugar
2 cups finely chopped black walnuts, for garnish (optional)
Directions
Melt butter in saucepan. Add brown sugar and cream. Cook over medium-low heat for about 2 minutes, until the sugar is dissolved. Remove from heat and add vanilla. Transfer to a large bowl.
Using a handheld electric mixer, beat in confectioners’ sugar until smooth. If frosting is too thick, add 1 tablespoon heavy cream at a time until consistency is right.
