In a large mixing bowl, combine cream cheese, unsalted butter, and peppermint extract. Use a handheld mixer to beat until smooth and creamy, about 2-3 minutes.

Gradually add green food coloring to the cream cheese mixture, mixing until you achieve a uniform vibrant green hue.

Begin adding confectioners' sugar, ½ cup at a time, mixing thoroughly after each addition until the mixture thickens into a soft dough.

Roll the mixture into ½-inch balls and place them onto a parchment-lined baking sheet.

Flatten each ball slightly with a fork, creating a uniform shape about ¼-inch thick.

Sprinkle red heart-shaped sprinkles on each flattened mint while still slightly soft.

Chill the baking sheet in the refrigerator for at least 1 hour.
