If the mixture becomes too soft, you can refrigerate the mixture for 10-15 minutes and then make besan laddus. In that case, you can reduce the amount of ghee the next time you make laddus.
In case if you are using besan sold for the purpose of making laddus, you can skip adding rava or sooji.
Shelf Life – 1 week at room temperature, if handled properly
