Prepare the fudge brownies based on the package instructions and allow them to cool completely at room temperature.
Remove the brownies from the pan. Remove the outside layer from the brownies and discard.
Crumble the remaining brownies into a large bowl. Mash the brownie crumbles together.
Add in the cream cheese and stir until combined. The mixture will be thick.
Line a baking sheet with parchment paper.
Shape the brownie mixture into balls and place them on the prepared sheet.
Freeze for 30 minutes.
In a microwave safe bowl, heat the chocolate chips and the shortening in the microwave in 30 second intervals, stirring after each one until fully melted.
Dip each brownie ball into the melted chocolate with a fork. Make sure that the candy covers the brownie ball completely. Allow the excess melted candy to drip off back into the bowl.
Place the coated balls back on the baking sheet and top immediately with the sprinkles if using.
Continue until all the brownie balls have been covered.
Freeze for 10-15 minutes until set and then the truffles are ready to enjoy!
