Peppermint Stout came to fruition a few years ago, under a different name, in the form of a body scrub.
I used it in my spa treatments as a way to put to use all of the coffee grounds I was brewing through.
The scrub is super simple to make:
1 cup coffee grounds (the larger the grounds the courser the scrub)
1/4 cup coconut oil*
4-6 drops peppermint essential oil*
Mix all of the ingredients together. Add more oil, depending on the desired consistency. Best to store in fridge when not using because this scrub is freshhhhhhh.
*liquid or solid coconut oil will work. I prefer the consistency of solid; I find it holds everything together better.
*essential oil is completely optional - it can be omitted or use which ever scent you like best.
