Kue satu or kue koya is one of the simplest and easiest kue kering (traditional cookie) in Indonesian cuisine. It consists of only four ingredients; mung beans, powdered sugar, vanilla essence, and water. The mung beans are sautéed without oil until their green skins are cracked. After the skins are removed, the peeled mung beans are mashed or ground manually using mortar and pestle, or using electrical devices like a food processor or blender. The powdered mung beans are then mixed with powdered sugar, vanilla essence, and a small amount of water to form a dough. This dough is then placed into small cookie molds and baked in the oven at 150 degree Celsius heat. Afterwards, the baked cookies are aired and sun-dried for several hours before being stored in air-tight glasses or plastic cookie jars.
The most common kue koya uses mung beans that created the white-colored powder. Another variant is called kue koya kacang tanah that uses common ground peanuts instead of mung beans, thus created a brown-colored kue koya.
