Tips

  • Use very soft butter to ensure a smooth, lump-free cream

  • Substitute espresso powder for instant coffee for deeper flavor
  • Use dark chocolate shavings for a more bittersweet finish
  • Chill briefly before spreading if mixture feels too soft

  • Can be piped if slightly chilled
  • Pair with yellow cake, chocolate cake, or sponge cake
  • Alcohol-free version: omit rum extract and increase coffee slightly
