A cake that travels well starts with frosting that sets up firm. This crusting American buttercream forms a light shell as it sits, so it pipes cleanly, holds detail, and resists smudging on the road — especially when you protect it with Icing Saver picks under the wrap.
Ingredients
- 1 cup (226g) unsalted butter, softened
- ½ cup (95g) high-ratio shortening (the key to a stable crust)
- 6–7 cups (750–875g) powdered sugar, sifted
- 2–3 tbsp heavy cream or milk
- 2 tsp clear vanilla extract
- ¼ tsp fine salt
Method
- Beat the butter and shortening on medium until smooth and pale, about 2 minutes.
- Add the powdered sugar one cup at a time on low, scraping the bowl between additions.
- Add vanilla, salt, and cream a tablespoon at a time until the buttercream is fluffy but holds a stiff peak.
- Beat on low for a final 2 minutes to knock out air bubbles for smooth piping.
Protecting it for the trip
Let the frosted cake crust and chill, insert Icing Saver picks above your tallest piping, and tent plastic wrap over the tops. See our full cake transport guide for the drive.
