In a medium mixing bowl or the bowl of a stand mixer fitted with a paddle attachment, blend together the sweetened condensed milk, peppermint extract and powdered sugar. Add food coloring at this step if you desire a color. Mix at a medium speed for 2-3 minutes or until mixture is smooth with no lumps. Dough will be stiff and form patties, but not dry and crumbly.
Line a large rimmed baking sheet with wax pr parchment paper. Roll dough into approximately 28 1-inch balls. Flatten each with the palm of your hand to make the filling for patties. Allow to dry at room temperature for at least 2 hours, flipping once.
Right before melting the chocolate place in the refrigerator or freezer for 15-20 minutes.
Melt chocolate in double boiler. Dip patties into chocolate, tapping on the side to get excess off. Place onto a parchment paper lined baking sheet to cool. If you desire sprinkles, add now. Place in the refrigerator for an additional 30 minutes to set.
