1. On high speed, beat together sugar and butter until fluffy, about 3 minutes. Add vanilla and cream. Continue beating until well combined, 1 minute.
2. Transfer half the frosting to a decorating bag fitted with a large star tip. Tint remaining frosting with gel food coloring until desired color. Transfer orange frosting to another decorating bag fitted with a large star tip. Pipe frosting onto cupcakes.
3. Note: To keep the frosting pure white, use clear vanilla extract.
