1. Preheat the press. Place the vessel containing the cake and heat it with a press on top. The cake will be ready in about 20–25 minutes.
2. You can also make cake using an electric steamer. If you have an electric steamer, steam for 25–30 minutes. Check by inserting a toothpick, if it comes out clean then the cake is ready.
3. Make the cake by setting it in the refrigerator. Add some condensed milk to the batter and let it set in the refrigerator for 4–5 hours.
