Everyone has their own tastes, but given relative quantities of the other ingredients, I’ve tried similar concoctions and found that 2T cocoa is too much even for me and I love chocolate and will even eat completely unsweetened baking chocolate.
I’ve also found that the resulting taste can depend a lot on the coconut oil itself - some of the ones I’ve tested didn’t have a strong coconut flavor, but the mixture reminded me of sugar alcohol in mouth “feel”, so I’ve started using 1 part coconut oil to 1 part butter instead of 2 parts coconut oil.
I’ll also use raw cacao butter instead of the coconut oil, but it is still rock solid at room temperature and I have to chop it up before it will even melt properly and it’s also more expensive.
Let us know if you find a variation that works for you.
