How to Make Chocolate Buttercream Frosting

  1. In a large mixing bowl or a stand mixer with a whisk attachment, add softened butter, shortening, vanilla, and cocoa powder. Mix well. Slowly alternate adding in confectioners’ sugar and evaporated milk, blending well after each addition.
  2. Frost cupcakes once they have fully cooled.

How to Decorate Yellow Cupcakes

I used Wilton’s 2D icing tip for the cupcakes in the photos. A 1M icing tip also works as a slightly more open star tip.
