I know we generally use the word, "Rice cake" for this Korean sweets "Ttuk"; 떡, but I always feel weird calling "Cake" for the one made out of sweet rice flour.
In Korea, there are two different types of rice cake,"Ttuk". One is made out of sweet rice flour and another one is made out of regular rice flour. Since sweet rice flour make "Ttuk" chewier, it is used for something smaller or bite size snacks, such as Mochi. And for regular rice flour, we normally make bigger "Ttuk" which is more like a cake. So that's why, I think I sometime we should just call them with their original name "Ttuk", like a Japanese word, Mochi.
