Preheat oven to 375 degrees F. Line two large cookie sheets with parchment paper. In a large bowl combine cookie dough and flour. Arrange 22 to 24 clusters of four or five pecans each about 2 inches apart on prepared cookie sheets. Shape dough into 1-inch balls. Place a ball on each cluster of pecans, pressing dough lightly into nuts but keeping edges of nuts exposed. Bake for 8 to 10 minutes or until edges are golden. Let stand for 2 minutes; transfer cookies to a wire rack to cool. Spoon caramel-flavored ice cream topping over the tops of the cookies.
