If anyone’s wondering, these were just made in rice cookers. (It has to be the nicer kind with the pressure cooker style lid not the cheap ones with just a simple glass lid.) I use mine all the time to make small coffee cakes; it’s the same thing with these giant pancakes. You just hit the white rice cycle three or four times until the pancake is thoroughly cooked. There’s actually a Japanese cooking blog that detailed all kinds of variations like making cheesecakes and pancakes with fruit filling and stuff like that.
