See how nicely the frosting piped out? Do you know what the secret is? .... Wait for it.... wait for it.... it's swiss meringue buttercream! Thank you Martha. Once you try this, you'll never go back to confectionars sugar buttercream. In fact, you might say "Yeck!" and turn your head away in disgust when a co-worker dares to bring such a concoction in for an office birthday. Hypothetically speaking, of course. SWBC (yes, we've achieved an acronym-level relationship) tastes like ice cream bliss and it's worth the extra effort.
