A rice cake may be any kind of food item made from rice that has been shaped, condensed, or otherwise combined into a single object. A wide variety of rice cakes exist in many different cultures in which rice is eaten. Common variations include cakes made with rice flour, those made from ground rice, and those made from whole grains of rice compressed together or combined with some other binding substance.

Rice flour is a form of flour made from finely milled rice. It is distinct from rice starch, which is usually produced by steeping rice in lye. Rice flour is a common substitute for wheat flour. It is also used as a thickening agent in recipes that are refrigerated or frozen since it inhibits liquid separation.
