Cream the butter and milk: In a large mixing bowl, cream together the softened butter and sweetened condensed milk until smooth and fluffy.

Add the powdered sugar: Gradually add the powdered sugar, one cup at a time, mixing until well incorporated. The dough will thicken as you add the sugar.

Stir in peppermint extract: Add the peppermint extract and a pinch of salt. Stir well to combine, creating a creamy mint-flavored dough.

Divide the dough: Split the dough into two portions. For a two-tone effect, add a few drops of red food coloring to one portion and mix until the desired color is achieved.

Roll the dough: Roll the dough into small balls, about 1 teaspoon each.

Shape the mints: Gently press each ball into small discs, or leave them as rounded shapes. These will be the signature form of the mints.

Roll in granulated sugar: Lightly roll each mint in granulated sugar. This will give them a lovely shimmer and an extra burst of sweetness.

Let the mints firm up: Place the mints on a baking sheet lined with parchment paper. Let them set at room temperature for about 1 hour, or until firm.

Storage: Once the mints are firm, transfer them to an airtight container for storage. They can be kept at room temperature for up to 1 week.

Serve and Enjoy: Serve these soft, buttery mints at your holiday gatherings or give them as gifts to share the holiday cheer!
