Preheat the oven to 350 degrees F. Grease and flour 24 mini muffin cups. Place 1 cookie dough round in each muffin cup. Gently press your thumb into each dough-filled cup, making a small indentation. Fill each cup with about ½ teaspoon chopped pecans.
Bake until light golden brown, 15 to 20 minutes. Cool in the pan, about 10 minutes. To remove from the pan, gently twist the cookie cups until they turn freely.
