Preheat the oven to 400degrees.
Separate the mini piecrusts, and arrange them into a cupcake pan. Poke holes into the bottoms with a fork.
Transfer the pan to the oven, and bake for 12-15 minutes. Remove from the oven, and allow to cool completely.
In a large bowl, mix the sweetened condensed milk, pink lemonade concentrate and food coloring on low speed, until well blended.
Fold in the whipped topping.
Refrigerate for 1 hour.
Divide mixture between the 24 pie crusts.
Add the remaining 1 cup of whipped topping to a piping bag fitted with a large star tip, and pipe just one “star” into the center of each filled pie bite.
Sprinkle with sanding sugar.
Refrigerate for 3 hours, then serve.
