Raspberry Frosting

Preparation

• • In a saucepan over medium heat, melt ¼ cup of the butter. Add the flour and cook for 1 minute, stirring constantly. Add the raspberry purée and bring to a boil, stirring with a whisk. Simmer over low heat for about 1 minute or until it thickens.
  • Pour into a large bowl, cover with plastic wrap directly on the surface to prevent the formation of a skin and cool to room temperature.
  • Add the sugar and the remaining butter (1 ¼ cups). With an electric mixer, beat at medium-high speed for about 5 minutes or until the frosting is smooth and creamy (see note).
  • The raspberry frosting keeps for up to 3 days at room temperature or in the refrigerator. If refrigerated, let warm to room temperature and beat again to restore its creaminess.
