Preheat oven to 350 degrees. Spray mini muffin pans with non-stick spray.
Prepare the brownie mix as directed on back of the box, using the ingredients for chewy brownies.
Fill muffin cups no more than 2/3 of the way full with the batter.
Bake in oven for 18-21 minutes, or until a toothpick inserted in the brownie comes out clean. Let cool in pan for 2 minutes.
Pressing very lightly, place a Kiss in the mini brownie. Let cool in pan for 10 - 12 minutes. Be careful when removing them from the pan as the candy is softened (melted). Cool completely on a wire rack and store in an airtight container.
