chiffon cake
A light, airy sponge cake made with vegetable oil, eggs, sugar, flour, and baking powder. In Japanese, it is often distinguished from a regular sponge cake (スポンジケーキ) by its use of oil and a taller, fluffier texture.
I baked a chiffon cake for my mother's birthday.
The chiffon cake at this café is fluffy and delicious.
