Grease a 12-cup muffin tin with nonstick cooking spray with FLOUR (like
this)*. Cut cookie dough into 12 even slices and press into the bottom and about 2/3 up the sides of prepared muffin cups. Bake for 18-20 minutes or until edges are barely golden. Let cool 5 minutes then gently transfer to a wire rack to cool completely (about 20 minutes).
