a type of biscuit or cake with a long, thin shape and rounded ends, that is soft inside and hard outside and covered with sugar. Sponge fingers are often used for making desserts (= sweet dishes eaten at the end of a meal).

In tiramisu, sponge cake can be used instead of sponge fingers.

Arrange the sponge fingers in the bottom of a trifle dish. 将手指饼干摆放在甜品盘底部。
