Bake the brownies according to the package directions. Let them cool completely, then crumble them into a large bowl.
1 16.3 oz box brownie mix
Add the softened cream cheese to the brownie crumbles and mix until fully combined. The mixture should be thick and sticky.
4 oz cream cheese
Use a small cookie scoop or spoon to roll the mixture into bite-sized balls and place them on a parchment-lined baking sheet.
Pop the bites into the freezer for about 20–30 minutes to firm up.
While they chill, melt the chocolate chips in a microwave-safe bowl in 30-second intervals, stirring between each, until smooth.
2 cups milk chocolate chips
Dip each brownie cheesecake bite into the melted chocolate, using a fork to gently shake off the excess. Place them back on the parchment paper.
While the chocolate is still wet, top with your favorite sprinkles—chocolate jimmies, rainbow nonpareils, or both!
Chocolate jimmies and nonpareil sprinkles
Let the chocolate set at room temperature or in the fridge for faster results.
