you can use whole wheat pastry flour for most items (understanding that not all "flour" is the same- there are different levels of gluten some are making certain things-bread vs pastry, etc)
Â
but the "sweetener" is dependent on what you are making-not all items will come out the same - goes for swapping a leveling ingredient - all are not equal, certain items call for only exact items some you can play a bit with and make it work
Â
sugar does not mean you can just add something else -ex honey and have it work, same goes for the amount - 1c. sugar does not mean 1. honey
Â
you would really need to state what you are thinking of making and what is called for in it to better see on swapping
