Prepare a heat-resistant mug. First stir the dry ingredients together, then stir in the wet ingredients until it turns yellow and there are no more lumps.

Place in the microwave on a high setting for 2 minutes. Let cool for 2 minutes and eat immediately. Otherwise, the mug cake will become hard after a while. (Tip: If it didn't work, the self-raisin flour may help. You can easily make it yourself: Mix 500 g flour with 1 sachet of baking powder and a pinch of salt. You have already made the English substitute flour!) I wish a good hunger!
