How to say "icing" in Japanese

• アイシング
  nounThe loanword for the baking sense: the sweet sugary frosting on cakes and other baked goods. It corresponds directly to English 'icing' in its food sense, not to ice on aircraft.
• 着氷ちゃくひょう
  noun, suru verbThe technical term for the aviation and maritime sense: ice accreting on an aircraft, a ship or a similar surface in freezing weather. It is never the word for frosting on a cake.
• 砂糖の衣さとうのころも
  nounA descriptive phrase, literally 'a coating of sugar', for the frosting on a cake. Use it when you want to describe the icing in terms of what it is made of.
• 砂糖衣さとうごろも
  nounThe same idea as a single compound: frosting, icing, or a sugar coating. Like 砂糖の衣, it refers to the sweet coating on cakes and similar treats, never to ice forming on aircraft.

For ice forming on aircraft or ships, use 着氷; for the sweet coating on cakes, 「アイシング」 is the direct loanword, while 「砂糖の衣」 and 砂糖衣 describe the coating as a layer of sugar.
