Chocolate Mint Snow-Top Cookies

1-1/2 cups flour
1-1/2 teaspoons baking powder
¼ teaspoon salt
10 oz. mint chocolate chips, divided
6 tablespoons butter, softened
1 cup sugar
1-1/2 teaspoons vanilla
2 eggs
About 2/3 cup powdered sugar

In a small bowl, combine flour, baking powder, and salt. Set aside. Melt 1 cup mint chocolate chips over low heat or in the microwave. In a large mixer bowl, cream the butter and sugar. Beat in the melted mint chocolate chips and vanilla. Beat in the eggs. Gradually beat in the dry ingredients and the remaining mint chocolate chips. Wrap the dough in plastic wrap and freeze for 30 minutes or until firm.

Preheat the oven to 350 degrees. Line cookie sheets with silicone baking mats. Shape the chilled dough into 1-inch balls, roll in powdered sugar. Bake for 10-12 minutes or until sides are set but centers are still slightly soft. Let stand for 2 minutes before removing to a wire rack to cool completely.
