A simple Swiss meringue lightens this buttercream frosting, making it easy to incorporate add-ins such as a homemade Blueberry-Corriander Jam. “It has such a great pillowy consistency, but it's very stable" says Sasha Piligian, who shared her technique. "I can manipulate it in endless ways, folding in curd, tahini, jam—the possibilities are endless.” Use high-butterfat (82% to 84%) butter, such as Kerrygold or Plugrá, for the richest taste. For a shortcut, use store-bought blueberry or blackberry jam.
This frosting is delicious, and it spreads beautifully thanks to the cream cheese, which lends an ultra-smooth finish to your cake. As a bonus, the tartness of the cream cheese cuts straight through the rich sweetness of the cake in the most delightful way. Beat down the frosting with a wooden spoon before spreading on your cake to knock out any extra air bubbles. This frosting would also be great with cupcakes or on a classic yellow cake.
This rich white-chocolate mousse filling for layer cakes can also be made with dark chocolate or milk chocolate.More Light-to Dark-Chocolate Dessert Recipes
