When ready to form cookies, place sweetened condensed milk and chocolate chips in a saucepan on medium low heat.
Stir just until chocolate is melted. Remove from heat and stir in cherry juice.
Using a small cookie scoop (#60) or your hands, form small round balls of dough. Place on an ungreased baking sheet about 1 inch apart. The dough is sticky so you may need to rinse your cookie scoop with cold water a few times while forming cookies.
Place an indentation in the center of each cookie. Add a ½ of a cherry in the indentation.
Top with chocolate frosting mixture fully covering cherry
Bake in a preheated 350°F oven for 10 minutes
Allow cookies to cool for a minute on baking sheet. Then remove and finish cooling on a cooling rack.
