I recommend using regular (deodorized) coconut oil for this; virgin coconut oil has a strong coconut flavor which I don't ordinarily mind, but I find it clashes a bit with the mint flavor. The mint flavoring I used was peppermint-based, but you could use one that's made from another type of mint, such as spearmint, adjusting the flavor to taste.
And be sure to use real white chocolate, not products labeled "chocolate coating" or "white coating." For more on white chocolate, check out my post:
What is white chocolate?
I used the chocolate ice cream recipe from
The Perfect Scoop, but I've linked to another recipe at the end of this post.
