The microwave oven will default to high heat if it is not adjusted. If your microwave oven does not have heat adjustment, it will be high heat. A heat of 100 means high heat. If you have a combination key, such as a light wave combination or a grill combination (the combination key means using the microwave and grill functions to heat the food together) you can also use this. Assuming that your microwave oven does not have high heat but medium heat, then you need to heat it for a longer time. Low heat is slower than high heat. Light wave ovens generally use light wave key combinations to make cakes. Press the "microwave key" to adjust the firepower. You can make cakes without pressing any buttons and just use the microwave function. Many microwave cake making methods on the Internet do not use the "bake" function and are made using the simple microwave function. You can also make cakes with a rice cooker. The result is a steaming feeling.
