This recipe makes a lot of icing, that is why it calls for many cups of confectioner's sugar and shortening. It will make enough buttercream to cover two, 8" round cakes or a layer cake plus extra for plenty of piping details. You can always halve the recipe if you don't need that much.
I do realize this isn't 'real buttercream'because it uses vegetable shortening instead of real butter. The point of this recipe is to use shortening to get a more heat-stable, pipeable and bright white buttercream. People have been calling this a heat-stable buttercream for many years and I am not the first. Now, if you want a 'real' buttercream recipe using all buttercream, you'll want to see that recipe here: Vanilla Bean Buttercream
Vegetable shortening is not lard. Vegetable shortening is plant fat and lard is animal fat. This recipe does not call for animal fat (lard).
This is similar to lots of other bright white, heat stable, pipeable 'buttercream' or icing that you'll find at bakeries, grocery stores and home bakeries all over the U.S. It has been used for many years by home and professional bakers alike and I've just modified it to make it taste better. If you've eaten a cake from the grocery store, it's likely you've had this icing.
