Prepare brownies according to package directions, baking them in a 9 x 13 inch pan.
Let them cool.
Use a football shaped cookie cutter to cut brownies into mini footballs.
You can also just use a knife to cut hand-cut the brownies into football shapes.
Frost the tops of brownies with chocolate frosting either by hand or using a piping bag and tip.
Pipe white laces on each brownie.
Notes
These are really fun to serve at game day parties! They look really cute sitting on top of a football field of green M&M’s or green jimmies. To make your own piping bag for white laces, cut a small corner off a plastic baggie. Put frosting in the baggie, twist it from the top to squeeze frosting out.
