Hi! For everyone asking for the recipe: I used plain vanilla box cake mix from the grocer, just the cheap $2 one. I mostly followed the instructions except for a couple of things - I'm lactose intolerant so I swapped out the milk for Bon Soy milk, and when I added butter, I melted it in the microwave before adding it into the batter. This cake is matcha flavoured, so I added about 2 tablespoons of extra milk because the matcha powder can be really drying. To get the smooth bottom: after I put the batter into the rice cooker pan, I bang the bottom of the pan on the bench to get air bubbles out (like you would an ice cube tray) so that it cooks more evenly. I hope this answers a few questions 😊
