In a stand mixer fitted with the paddle attachment, mix together 5 pounds brownie mix, 15oz room temperature cream cheese, and 5oz water. Mix on low for one minute, scrape the bowl, then mix on medium for 30 seconds. Line a half sheet tray with parchment and spread batter evenly (it will be thick). Bake at 350F until set all the way across, roughly 25 minutes.
Let cool completely, freeze for 4 hours. Cut frozen brownie tray into 1x1 inch squares.
Melt chocolate, dip brownie bites into chocolate and decorate as desired.
