This enormous pancake is made in a rice cooker! No need to stand over the stove and flip individual pancakes. Instead, just pour in the batter and let the rice cooker do the work.
When it is done, the cake will have slightly pulled away from the edges of the pan. The surface may look slightly wet, but it is likely from condensation. When you touch the cake, it should feel firm and bounce back. A toothpick inserted should come out clean. Let cake cool a few minutes. Then invert the cake onto a plate (the cake should slide out easily), and the surface of the cake should be brown.
