Combine the softened cream cheese and confectioner's sugar in a large mixing bowl. Add the peppermint extract.
Scoop the filling out and onto a large piece of plastic wrap. Close the plastic wrap tightly and refrigerate for 1 hour.
Roll the truffles into one-inch balls and place on a baking tray covered in parchment paper or silcone mat. Return to refrigerator.
It's easier to keep the balls in the fridge and grab a few at a time as you cover the balls in chocolate. Submerge into the melted chocolate and swirl to coat; carefully lift out using a fork. Tap the fork/tool gently on the side of the bowl/measuring cup to let excess chocolate drip off. Use a toothpick to help slide the truffle off of the fork and onto a lined baking sheet.
