Make brownie mix according to package directions.
Spray 12 muffin cups with non-stick cooking spray. Fill cups 2/3 full with brownie batter.
Bake according to package directions. I baked mine for 20 minutes at the temperature on the package.
While brownies are baking spray the bottom side of another muffin tin with non-stick cooking spray.
When brownies are done baking, remove from the oven and place the prepared muffin tray on top of the baked brownies and press down to form cups. Let cool.
When brownies are cool, remove top tray and remove brownies from tray.
Fill with a scoop of ice cream and top with hot fudge, sprinkles, nuts and a cherry.
