While brownies are cooling let ice cream sit out on the counter until it becomes soft enough that you can spread it a bit. (don't let it get too thawed but it should be easy to scoop & spread)
Once brownies are cool & ice cream is ready, scoop ice cream on top of brownies & spread into an even layer
Top with chocolate syrup & spread to cover the top
Add chocolate sprinkles
Cover with plastic wrap & freeze a minimum of 4 hours to re-set the ice cream before serving
