Chocolate Protein Balls

Instead of Cashews, could you use macademia nuts here?
Also, for the dates, if it is not “deglet nour”, does it make a big difference?
Instead of protein powder, is there any substitute? ty

It would be better to stick with cashews and macademia nuts are higher in fat so you would have to use less.
Deglet nour dates aren’t as sweet as other dates but still okay to use.
You can use any protein powder, you don’t have to use pea protein.
