Wow, 8 sticks of butter for a single batch of buttercream – that doesn’t even cover an 8 inch cake – does seem excessive. Are you making a standard American buttercream, or perhaps a Swiss style buttercream? I have recently started using the recipes for both from Global Sugar Art (globalsugarart.com) and find both recipes, which use no more than 4 sticks for a single batch recipe, are ample with enough to frost and pipe decorations on a 9" layer cake, with some to spare.
