Heat oven to 350°F. In bowl, break up cookie dough. Stir or knead in 1/2 cup all-purpose flour until well blended. Shape dough into 72 (1-inch) balls. On ungreased cookie sheets, place balls 2 inches apart. Bake 10 to 14 minutes or until edges are golden brown. Cool completely.
In microwavable bowl, microwave chips and 2 tablespoons vegetable oil uncovered on Medium (50%) 2 to 3 minutes, stirring once halfway through microwaving, until melted. Stir until smooth.
Dip half of each cookie into melted mixture, allowing excess to drip off; place on waxed or cooking parchment paper-lined cookie sheets. Sprinkle each with slightly less than 1/2 teaspoon crushed candy. Let stand until set.
