If the coconut isn't already toasted, toasting will amp up the flavor.
Also, coconut cream powder! $1-2 per packet at Asian grocers. I mix it with toasted coconut and white chocolate in my coconut bars.

I would not add more coconut oil, the coconut and macadamia will release plenty on their own. Does this get mixed with chocolate?
