Reddit reviews A Piece of Cake

I'm a big fan of Mousseline buttercream if I'm doing something fancy and I want to achieve a really smooth surface. If you're an avid baker you probably have it, but I love Susan Purdy's A Piece of Cake. She has some pretty great icing recipes in there as well as almost every kind of cake you can imagine.

I haven't made a marshmallow buttercream but I need to learn, that sounds really good. I can see pairing that with a chocolate cupcake and sprinkling graham cracker crumbs over the top...
