Swirl buttercream frosting

  • In a stand mixer fitted with a paddle attachment, beat the butter on medium speed until creamy (1-2 minutes). Reduce speed to low and gradually beat in the confectioner's sugar. Mix in vanilla and salt. Add in the heavy cream and beat until light and fluffy. Transfer half of the frosting to a bowl. Beat cocoa powder into remaining frosting on low speed until combined (1-2 minutes).

  • Fit a large piping bag with a large star shaped tip (I did use others as well). Lay out a piece of plastic wrap on a flat surface. Layer in a line the white frosting and next to the white lay the chocolate frosting in the same manner. Roll plastic wrap away from the body, fold the top over and cut the bottom end of the plastic wrap. Place the roll in the piping bag fitted with the star shaped tip. Pipe onto cupcakes and serve!


  • Store cupcakes in an airtight container for up to 3-5 days. 
  • Frosting can be store in the refrigerator for 3 days
