1️⃣ Improved Flavor: Shortening is 100% fat with a completely neutral taste. Adding butter introduces that signature rich dairy flavor so the icing tastes more traditional and less bland.
2️⃣ Better Mouthfeel: 100% shortening-based frostings can leave a greasy or waxy film coating the roof of your mouth. Butter melts at body temperature, giving the frosting a smoother, more pleasant texture.
3️⃣Weather Stability: Pure butter melts easily in warm temperatures, causing cakes to bulge or decorations to droop. Adding shortening gives the frosting a higher melting point, helping it hold sharp edges and stand up to room temperature longer.
4️⃣ Brilliant Color: Because butter is naturally yellow, making an all-butter icing can ruin a "pure white" cake design. Shortening keeps the base much whiter, making it a perfect canvas to add food coloring or to achieve a bright, clean look.
