If there was ever a luscious bit of airy, foamy heaven this Lemon Curd Mousse Cake has got to be it! Crumbled shortbread cookies form the bottom crust, topped with a creamy, dreamy Lemon Mousse filling. What really seals the deal, though, is the bright lemon curd shimmering across the top. Just to pretty it up, it’s decorated with rosettes of the lemon mousse and slices of lemon.
