Place the Pepper Mint candy in a food processor and process to get a powder.
In a bowl of a standing mixer, beat butter on high until smooth.
Change speed to low and add the powdered sugar 1 cup at a time. Once the sugar has been added fully, increase speed back to high.
Add the salt and peppermint extract.
Add the milk, a table spoon at a time, to avoid a runny filling. Beat the filling for about 5 minutes.
