Moist and rich chocolate cupcake with a cool mint chocolate chip buttercream.
If you want to pipe your frosting, make sure you use a large enough tip like a Wilton 8B or 1A
**You can store the rest of the buttermilk in the freezer in small plastic containers and when ready to use for another recipe, simply thaw and stir. Alternatively, you can make your own buttermilk by adding 1 tbsp of white vinegar to a liquid measuring cup, then add enough milk (1% or higher) to make one cup. Let stand for 5 minutes.
