Meaning
A triangular slice of layered sponge cake with white cream and a strawberry on top. It is the Japanese strawberry shortcake, but it stands for cake slices and dessert in general.
People send it for birthdays, café dates and treat-yourself moments: “Coffee and 🍰 at the new café after class?” For a whole cake with candles, 🎂 is the better match. The phrase ‘piece of cake’ also turns it into a symbol for something easy.
