First, maybe it's because you didn't operate the jinao pot correctly, because the heating plate in jinao is arc-shaped and easy to fall off automatically, so when you flip the jinao to dip the batter, don't turn it over immediately. You can let it stand in the air for 1-2 seconds, spread the batter evenly on the heating plate and then turn it over.

I just discovered this recently, because I bought Murphy light jinao. I didn't pay attention at first, but I turned it over immediately after using the hot plate and found that the batter seemed uneven. Then I asked the customer service to know that you can let it stand in the air for 1-2 seconds after dipping, so that the baked cake looks better and more uniform. You can have a try.

Second, it may be because your batter is not well mixed and mixed evenly. This is based on my previous experience in using other frying pans. Because the Murphy jinao I bought came with a basin and a measuring cup, I put a proper amount of flour and water in the basin according to the recipe, and then stirred it for more than a dozen times, which was quite even, so there was no such problem. According to my practical experience, after mixing the batter, you can let it stand for a while, which is more suitable for making pancakes ~
